THE PEONY FLOWER WANTS TO BE BEAUTIFUL, MUST SPREAD FERTILIZER PROPERLY

If you want to peony blossom well, proper management can not be less, especially fertilization is more important, the following simple talk about peony fertilization problem!

1.when should peonies be fertilized? How to fertilize?

We know that the peony flowers from April to May, and the peonies are already in full bloom at the beginning of April every year. In order to make the peonies bloom more beautifully, with bright colors and large buds, it is necessary to fertilize them in spring, spring fertilization can be in February or March, when the temperature is more than 10 degrees, simply use some decomposed organic fertilizer, animal bone powder and so on, of course, you can also use a mixture of some quick-acting phosphate fertilizer, these can play a role in forcing flowers, let peonies bloom beautifully.

After flowering, peony has consumed a lot of nutrients, it can be said that the vitality of the damage, AH, after the flower is generally cut off in time, and the use of compound fertilizer, to help peony flowers restore energy reserves, beautiful growth.

It is more important to apply fertilizer three times, this time after autumn, in order to bloom better in the coming year, and to improve the ability of peony flowers to keep out the cold. This time, it should be mainly decomposed manure, such as fermented pig manure, sheep manure, etc. , take care to properly mix up some phosphate, potash or compound fertilizers.

2. what problem should peony flower fertilize notice?

When applying fertilizer, peony flowers should be mainly decomposed organic fertilizer, mix chemical fertilizer properly, this can improve the soil, improve the flowering quality of peony flowers, but we need to note that the root system of peony flowers is a fat fleshy root, fertilization concentration can not be too large, a fertilization can not be too much, otherwise very easy to corrode fat fleshy root.

In addition, the quick-acting liquid fertilizer is generally not recommended to use, especially fecal water can not be used. In addition, the absorption capacity of the root system has declined in the hot summer and winter, and it is not recommended to apply fertilizer, such as oil or pills. These remedies should not be used indiscriminately. The clean and elegant peony is not a garbage collection station, it doesn’t just come and go.

Spring tree peony management technology

Spring returns to the earth and all things come to life. Peony after a winter of dormancy and into the growth period. A lot of people like this “national beauty” of the peony. But how to manage and protect the peony in spring is very difficult. We should know that the management and maintenance of the peony in spring can directly affect the quality of flowering and growth after flowering, so we must take it seriously. There are four main points to note.

Watering spring should be early rather than late, flowering should be controlled watering

The temperature rises quickly in spring, but there is still a cold wave invasion, extremely unstable. It is necessary to water the peony early in spring to avoid the harm of late frost and cold in spring. Watering in early spring can effectively reduce the ground temperature and delay the germination of plants. If watering too late, not only can not play the role of anti-cold, anti-freeze, will affect II to flowering quality. Therefore, spring water should be early rather than late, in early spring is better, but to grasp the moderate watering, at this time watering should also see the principle of dry see wet, watering will be through, to soil surface without water for degrees. Peony flowering period should be controlled watering, such as watering too much will shorten the flowering period, so that the flowers wither prematurely. As the saying goes, “dried flowers and wet fruits” , this is the truth.

Prune in time and remove buds properly

It is very important to Prune Paeonia Suffruticosa at the base of the tree in spring. Practice has proved that if the peony is not pruned properly, the flowers will be small and light, and the growth will be affected. Peony pruning, there are three main aspects: one is to peony pedicure. All the new soil buds should be cut off, except for those used as new shoots or for correcting crown shape, so as to avoid consuming a lot of nutrients and affecting the quality of flowering and the differentiation of summer flower buds. The second is to remove too many buds. Should be in line with the weak to stay strong principle to dredge bud, only one strong bud can be kept in each branch (Fig. 2. In this way, nutrients can be concentrated so that the flowers are in place. Third, the remaining flowers that do not intend to remain in the plant should be cut off to prevent excessive nutrient consumption due to their fruiting.

Timely fertilization, flowering to shade

Spring to the peony fertilization, must be applied twice, that is, in early spring before the flower fertilizer and Zhongchun after the flower fertilizer. In the daily management, people often neglect the post-flowering fertilizer, in fact, this fertilization is very important, directly affect the growth and flower bud differentiation of peony. Although fertilizer was applied before flowering, after flowering, nutrient has been consumed a lot. If fertilizer is not applied after flowering, the growth of plant will be affected directly, the growth will decline, and the flower bud differentiation will be affected. Therefore, generally half a month after the flower, to topdressing a phosphate-based compound fertilizer, but also can be appropriate to apply some mature fermentative circle fertilizer. If the plant growth after flowering is not good, you can also use 0.2% Monopotassium phosphate solution for leaf topdressing, so that the plant can flourish. At the same time pay attention to the flower after the appropriate shade figure 4. Peony although like light but avoid exposure to the sun, flowering season in the shade of the best growth. At the beginning of May, the light is already very strong in most parts of China. At this time, the peony is in full bloom. If the peony is not properly shaded and exposed to the sun, the environment temperature is too high, it will not only shorten its flowering period, and also easy to make the blooming peony flowers lose luster, thus reducing the ornamental value. Therefore, the peony flowering period should take appropriate shading measures, as far as possible to make it receive before 9:00 a.m. and 5:00 p.m. after the light. This can make the flower big bright, flowering period is prolonged, still can effectively avoid the leaf is sunburnt by the sun, appear scorch edge and so on. If you do as above, the peony will be pleasing to the eye. Heze Duohe Peony, a professional planting base

Don’t relax in pest control

Although spring is not the peak season of peony diseases and pests, if the control work is relaxed, the plant will be attacked by diseases and pests during the growing period, even the whole plant will die. Therefore, it is advisable to spray the plant with a mixture of 3-5 baume’s degree of lime-sulphur once before leaf-opening in early spring, and 50% thiophanate-methyl 1000 times every 15 days after flower-setting, it can also be used alternately with 50% CARBENDAZIM WP 800 times liquid, which can effectively control fungus diseases such as black spot, stem rot and leaf blight. Spring Peony will be aphid harm, such as the occurrence of available Omethoate, Dichlorvos and other broad-spectrum insecticide to kill, so that will be a variety of diseases and pests in the cradle, receive twice the result with half the effort

5 tips for growing peony

1.Best planting time: The best planting time for peony is mid-september to late 10.

2.The best growing soil: Peony cultivation soil texture loose, fertile, neutral alkali.

3.Growth humidity requirements: Peony watering to both keep the soil moist, but not too wet, not water for the principle.

4.Optimal growth temperature: Peony cold-resistant, not resistant to high temperature. In Eastern and central China, the flower buds began to expand gradually when the temperature reached 4 °C. SUITABLE TEMPERATURE: 16 ~ 20 °C, less than 16 °C do not bloom. When the temperature is high in summer, the plant is semi-dormant.

5.The Best Growth Light: Peony like the Sun, but do not like the Sun. When the ground is planted, need to choose a higher position facing east, potted should be placed in the sunny east balcony, such as the south balcony or roof platform, the west should try to shade.

The most common types of tree peony flowers

Since ancient times, peony is considered as a symbol of wealth, peony flowers large, beautiful color, colorful, very beautiful, pleasing to the eye.

Peony experts and scholars and related researchers have proposed flower type classification, namely Peony Flower type includes single-petal type, Lotus type, chrysanthemum type, rose type, melaleuca type, hanging type, gold ring type, crown type, hydrangea type, tower type these several kinds.

The petals of a single peony flower have more than ten, two to three rounds, broad shape. The results are stronger. This kind of flower type represents to include opium purple, Garnet Red, Feng Danbai to wait.

Lotus-type peony flowers have many petals, there are more than 20, there are four to five rounds, its orderly arrangement, broad shape, with individual stamens and pistil stigma petalization of the situation. The representatives of this type of flowers include lotus-like, Jinyunhong, Yubanbai and so on.

The flower shape of moutan peony decreases gradually from the outside to the inside, its arrangement is neat and clear, its petals have six rounds or more, but its bearing ability is poor.

The rose type peony flower is similar to the Chrysanthemum type in shape and petals, but its fruiting ability is not high.

The lower petal of Melaleuca type peony is more, the stamen is normal, the lower petal is less, the shape is flat and the stamen quantity is small. Its representatives include fat red, longevity red and so on.

Hanging peony flower part of the stamens into long and slender petals, petals arranged in an irregular, strong, such flower type on behalf of including ladies, Jiaohong, Xiane and so on.

There is a circle of normal stamens between the Middle Petal and the outer petal of the gold-ring type peony flower.

The name of the crownlike peony flower resembles a crown because of its dense and towering petals. IRREGULAR SHAPE, occasional petalization and degeneration, on behalf of a blue field jade, Hu Hong, Yao Huang and so on.

Hydrangea peony petals crowded uplift, showing a ball-shaped, no seed-bearing capacity, on behalf of varieties such as green, Green Incense Ball

Why is it so hard for a novice to grow tree peonies

One is the growth of peony do not understand, two is to hire workers in order to fast, save energy. Planting too shallow will lead to bad root, root and stem joint hidden buds not buried in the soil, the winter wind easily blow dry the root and stem of this piece of water, seedlings easy to dry up or even die, the next spring is not easy to produce more branches.

The root of the soil washed clean can be seen at the root-stem junction hidden bud, some obvious, some not obvious.

2. tree Peonies are less watered

Especially in arid areas, the seedlings do not grow well in the coming year, even when the sun is strong at noon, the stems and leaves wilt, and the stems and leaves stand up again in the morning and evening, mostly because of too little or no fixed root water when planting. There are arid areas where the winter monsoon is relatively strong and there is little snow, and winter water must be poured when the land is frozen in winter.

Drought tolerance of tree peony means that tree peony can survive and grow for at least one year before drought tolerance, because the tree peony has produced enough fine root, and its fleshy root developed more robust, stored more nutrients and water. Fear of waterlogging refers to the accumulation of water can not exceed 3 days, the day of the big water, 24 hours of water can disappear is no problem.

3. Do not understand the importance of planting time and management

The southern soil moisture is big, the winter temperature is high, the rooting cycle is long, the root growth quantity is big. The planting time can be later than October. When planting, the new roots are more suitable for southern soil, and the measures of planting and root-cutting can avoid the occurrence of root rot to some extent.

Northern Autumn temperature fall faster, planting time as early as possible, so that the peony root growth time will be longer, the growth of the root will increase, the next year will be vigorous seedling growth. The colder the area, the earlier the planting, the end of the heat can be planted. Peony planting in the north, generally according to the size of the seedlings to take measures, flat stubble, do not give up branches, cut off the branches, let the new growth of branches to grow, new long branches grow better, more able to adapt to the cold windy climate in the north. Of course, flat stubble is for the series of seedlings, for transplant with soil ball semi-formed or formed peony, it needs to be a certain amount of pruning, and do not need flat stubble.

The method of tree peony seed seedling

1. Picking seeds, generally in early August, peony seeds mature one after another. The seeds are initially white, nearly Brown at maturity, and black at maturity. When the fruit was picked crab yellow, put indoor cool damp place, make the seeds in the shell after ripening, and often turn, so as not to heat, until most of the fruit cracking, seed emergence. Do not dry in the sun, or the seeds often do not germinate.

2. Seed treatment, the seeds out, should be sowed immediately, sowing late, the next year does not germinate, or even wait until the third year of Spring to Germinate. If it is too late to sow, wet sand burial method can be used, planting sand ratio of 2:8. This about 30 days, bud tip slightly exposed, and then sowing in the field, the following spring is still normal germination. Direct sowing or quickening germination in sand, the seeds should be soaked in 50 °C warm water for a day and night to make the seed coat soft, absorbent and expand, easy to germinate and germinate.

3. PAEONIA SUFFRUTICOSA is not very high demand for soil, choose permeability of sandy soil or loam soil, soil adaptability is more extensive, do not viscosity too much soil can be

4, Management, in order to prevent soil moisture evaporation, can shade in the seedbed, it is best not too much water, because watering more soil will harden. After entering November, sunshade can be removed, before the frost with Straw, grain grass or leaves covered seedbed to prevent moisture preservation, until the next year in February to remove the cover, start

watering.

Peony common 8 kinds of pests and diseases

Peony Growth and development process, if properly managed can live for decades or even centuries. If the growing condition is poor, the tree peony is often damaged by diseases and insect pests and the influence of bad environment, resulting in many spots and incomplete leaves, weak growth of branches, dry root system, rot or development deformity, thus greatly reducing the ornamental value,

gray mold

Botrytis CINEREA is one of the most important diseases in the world. The disease can occur in the growing season of tree peony.

Symptoms

The disease endangers the stems, leaves and flowers of peony. When the stem appears Brown spots, rot, seedling withering and lodging. Infected leaves produce irregular water spots, leaf tip and leaf edge spots more, brown spots, but also purple-brown, sometimes with irregular ring pattern, wet weather department gray mold. Petiole and leaf stem disease spot for more long, dark brown, a little depression, disease department easy to break. Infected Flower Buds Brown, dry, Brown petals, rot. Under moist conditions, gray mould layer can be formed at the site of the disease. The disease is a fungal disease.

Low temperature and humidity are the main conditions of the disease. In spring, the temperature is lower and the continuous rain will aggravate the disease of the seedlings. The disease often occurs after the flowering period of the host, 6 ~ 7 months, more nitrogen fertilizer, is conducive to the disease.

Control method

1. Combined with yard cleaning, timely removal of diseased leaves and plants, and focus on burning.

2. In case of disease during growing season, the following medicament can be used for spray control: 1% lime equivalent bordeaux solution, 70% thiophanate-methyl 1000 times solution, 65% ZNZN 500 times solution, or 50% chloronitramine 1000 times solution. Spray every 10 to 15 days, 2 to 3 times in a row.

3. The density of planting should be moderate, the plant should be drained in time after rain, the plant should not be moistened from the base, the rotation should be carried out in the serious disease area, and the seedling should be planted without disease, the seedling can be disinfected by soaking for 1015 minutes in 65% ZINCON 300 times solution.

Brown spot disease

Brown spot disease, also known as the red spot disease, the disease is widespread, serious harm, disease rate of leaves can reach 89.3% , often cause early blight, affect the growth of peony.

Symptoms

Brown leaf spot mainly damages the leaves of Tree Peony, but also infects branches, flower organs, seed and other parts. In the early stage of the disease, there were large round or irregular spots on the leaves, which were Brown on both sides. When the disease was serious, the spots converged and caused the leaves to be withered and twisted, and dark green mould layer appeared on the back of the spots under moist conditions The spot on the flower organ is Brown spot, and the edge of the petal is scorched when the disease is serious. The spot on the flower organ is Brown spot, and the edge of the petal is scorched when the disease is serious. The disease is caused by fungi.

The disease is more serious in warm and rainy conditions, more pathogens, more nitrogen fertilizer, higher planting density and poor ventilation and light transmission. The high temperature rainy season is the peak period of disease.

Control method

1. To reduce the source of infection, Autumn thoroughly remove the debris on the ground, spray 50% CARBENDAZIM 600 times liquid or 3 baume degree sulfur mixture before germination of plants in early spring to kill the bacteria.

2. Starting from early May, 50% MANCOZEB 500-fold solution or 75% CHLOROTHALONIL 800-fold solution was sprayed once every 15 days for 3 ~ 4 Consecutive Times.

3. Planting density is moderate, apply organic fertilizer and compound fertilizer.

4. Clean the field in winter, then spray the stem with 7 ~ 10 times lime-sulfur mixture.

Anthrax

ANTHRACNOSE is a common disease of tree peony in China. The United States, Japan and other countries have also reported. Anthracnose often makes peony leaf withered spots, twisted stems, young shoots dead.

Symptoms

Anthracnose of Tree Peony damages leaves, stems, flower organs and other parts of Tree Peony. In late April, round purple-brown spots appeared on the leaf surface, petiole and stem, and gradually expanded to nearly round spots. The size of the spots varied from 4 mm to 25 mm in diameter, and the spots on the leaf margin were semi-elliptic The expansion of the lesion was semi-elliptic due to the influence of the main vein.

The black spot reveals color, the middle part of the late period is gray-white, the spot edge is red-brown. There are many black spots on the spots. In the humid condition, there are red-brown sticky clusters on the spots. This is the characteristic of anthracnose. The lesions dehiscence and perforation in the late stage. On stem and Petiole of disease spot is lozenge mostly, a bit sunken, long 3 ~ 6 millimeter, red-brown; later period is gray-brown, edge is red-brown. The diseased stems are twisted and break when they are seriously ill. The young stems become diseased and die off quickly. Bud Scales and petal damage can cause flower bud death and Corolla deformity. The disease is a fungal disease.

The onset of the disease usually begins in late April, and the peak period is from August to September. High temperature, more rain, more dew, plant cluster closed easily induced diseases.

Control method

1. Cut off the victim and burn it.

2. At the initial stage of the disease (may-june) , 70% of furosemide 500 times, or 1% of lime equivalent bordeaux solution, or 65% of thymosin 500 times, 10-15 days, a total of 2-3 times.

3. Keep the plants well ventilated to avoid high temperature and humidity.

Purple Feather Disease

It belongs to fungus disease. Mainly from the soil and spread with the root when planting separately.

Symptoms

The disease occurs at the base of the trunk near the ground and at the root. The young roots or the neck of the roots are covered with purple or white cotton-like Hyphae, which appear yellow-brown at first and black later. After the disease, peony old roots rot, new roots do not grow, thin branches, germination late, leaves become small, from the bottom up withered and yellow wither, branches in death.

The disease can occur at any time, not limited to plum festival, but the early summer rainy season more common. Raw Land, low-lying wet land or improper fertilization (the use of raw fertilizer, heavy fertilizer) , the most susceptible to disease.

Prevention and Control Methods 1. Select high dry terrain, good drainage of loose soil, fertilizer to fully mature, avoid direct contact with the fertilizer roots.

2. Separately, can use 0.1% of copper sulfate solution immersion root 3 hours, or half an hour with lime water immersion, and then rinse with clear water replant.

3. If the disease is found, the rotten parts should be removed immediately or scraped off with a knife, and then disinfected with 4-5 Baume's lime-sulphur mixture or sulphur.

4. At the beginning of the disease, 50% ZINCON 1000 times solution can be used to irrigate the roots, 500 ~ 1000 ML per plant

5. Rotation is carried out every three to four years.

5. Rust

Rust fungus is a host, the intermediate host is Paeonia Lactiflora, anemones, strychnine, pine and so on, so the peony nurseries near the plant can not be planted.

Symptoms

The leaves are fading Green, and the leaves are backed by piles of yellow boulders. In the late growth period, columnar hairs grow on the diseased leaves.

Control method

1. Remove and destroy the infected plant.

2. Planting should be high and open, with good drainage.

3. Before the onset of the same amount of Bordeaux liquid 160 times dilution, or spread 400 times of Zineb.

4. After the onset of stone sulfur mixture, dixie sodium, Triadimefon and other prevention and treatment.

White Silk Disease

SCLEROTIUM ROLFSII mainly occurred in the stem base near the ground. After the disease, the CORTEX of the stem base and root rotted, the water and nutrient transportation of the plant was cut off, the leaves became yellow and withered, and the whole plant died.

Symptoms

White Hyphae were formed on the surface of the root neck at the initial stage of the disease, and were covered with Silk Hyphae when the disease was serious.

Control method

1. First, root neck lesions were thoroughly scraped off with a knife, and the wound was disinfected with 1% copper sulfate solution. At the same time, the soil around the infected plant was opened up, and 70% pentachloronitrobenzene was mixed with the new soil in a ratio of 1:100, and evenly scattered in the soil around the diseased root.

2. The soil around the roots was irrigated with 50% ZNZN 400-fold solution.

Stem Rot

In the stem near the ground waterlogged spots occur, gradually expand rot, appear white woolly. Small initial markings on leaves, gradually enlarging to large gray-white and Hazel Markings, white spongy in wet weather. When the bud is injured, there are dark brown spots, and then rot.

Control method

1. Extirpate the diseased plants and disinfect the soil.

2. Healthy disease-free plants should not be planted in diseased areas.

3. Equal Dose Bordeaux Mixture.

Root Rot

Damage the root, so that the root black rot, serious when the whole plant death.

The method of prevention and control is to dig out the diseased plants and burn them, and spread some sulfur powder or lime in the planting holes to disinfect the soil
