Management of tree peonies in spring

 tree Peony is a small deciduous shrub of the genus Paeonia in the family Paeoniaceae. Its flowers are large in color and various in appearance. It is one of the ten most famous flowers in China and has a good reputation as“The beauty of the country and the fragrance of heaven” and“The king of Flowers”. The flowering period of peony is from April to May. Spring is a critical period for the growth of peony. In order to ensure the quality of flowering and post-flowering growth of tree peony, the following field management measures should be mastered.

1 pay attention to cold, scientific watering

In China, peony sprouts in early spring in early February and the climate is changeable in early spring. In order to avoid peony being hurt by cold current and late frost, we should pay attention to cold prevention work and water in early spring to lower ground temperature and delay sprouts. Water to choose the warm weather when watering, and in the peony is about to bloom when you want to stop watering.

2 appropriate shaping and pruning, wiping bud

sparse budIn early spring, flower bud germination, flower bud development, growth of sprouting shoots, to ensure the healthy growth of peony flowers, large, pure color, fragrance, do a good job, do fine pre-spring flower field management is very important. Plastic and pruning is the focus of field management in spring, the correct plastic and pruning methods are particularly important, including the following aspects.

2.1 peony pruning

On the basis of winter pruning, the missed overlapping branches, cross branches, thin and weak branches, inward growing branches, pest and disease branches were“Pruned”. To truncate and top off the branches whose terminal buds are leaf buds or abnormal buds to remove the sprouting tillers so as to concentrate the nutrients on flower buds.

2.2Paeonia suffruticosa sprouts refers to the removal of the root sprouts grow out of the adventitious buds, commonly known as the“Soil bud.”. Peony basic plant type fixed, there are still a considerable number of“Soil bud” germination every year, “Soil bud” to remove to ensure that the main branch of nutrition, will be colorful. However, not all“Sprouts” must be removed, according to the needs of plant type and old branches renewal, can be appropriate to retain and cultivate strong“Sprouts.”.

2.3Peony blossom has“Big and small year” phenomenon. When the peony bud, according to the tree and last year flowering situation, the appropriate bud thinning. It is better to work early rather than late. If there are many buds in that year, can be regarded as“Big year”, should be thin on the thin branches of the small and thin part of the buds to sparse, thinning about 1/3 of the total plant buds. For newly planted peonies, all the buds should be removed in the next spring to prevent them from blooming, so as to concentrate nutrition and promote development.

3 fertilize

Reasonable fertilization can make the peony flower color more gorgeous, the flower shape more plump, the petal is bigger, fully displays the peony’s elegant and the national color heavenly fragrance. Fertilization should be carried out before peony blossom, and it is suitable to show bud to Little Wind-bell period. The main fertilizer was quick-acting fertilizer, and phosphorus fertilizer was applied. N-p-k compound fertilizer or calcium superphosphate, which is mainly applied as nitrogen fertilizer, is generally applied. The ratio of N, P and K was 2∶2∶1 or 2∶1∶1. The method of fertilization and the amount of fertilizer should be based on the tree peony seedling size and production purposes. Among them, more than 5 years to ornamental-based adult plants, the plant spacing is larger, you can take hole application. In a place far from the root of the peony, shovel digging depth of 15 cm about the hole, each hole into fertilizer 20-30 g, after applying soil cover. For young seedlings, the amount of fertilizer should be controlled at about 10g per plant. The newly transplanted plant may be free of plantar fertilizer during the first spring because it was fertilized at the time of planting. For the plot of seedling breeding, because the spacing between plant and row is small, the fertilizer dosage of sprinkling or furrowing strip is 20-30kg/667m ~ 2 compound fertilizer. Do not over-fertilize, so as not to cause fertilizer damage, affect the growth of peony. After fertilization, watering in time can help the root to absorb nutrients better and transport to the bud part of the plant to ensure good growth. Fertilization operation should be careful, the bud is very easy to be knocked off, artificial or mechanical operation, try not to bruise buds and branches, reduce mechanical damage. In half a month after the end of the flower, to apply 1 times to the main compound fertilizer, phosphate fertilizer can also be applied by some appropriate mature fermentation of the ring fertilizer. If the plant does not grow well after flowering, it can also be fertilized with 0.2% Monopotassium phosphate solution on the foliage to make the plant flourish.

How to manage the tree peony after flowering

 The peony is known as the national flower, represents the wealth, the family is happy, is in the Chinese mind the most perfect flower.

Peonies bloom brightly and their fragrance is so strong that people can't wait to return. However, many flower friends don't know how to manage the peonies after they have blossomed, so, the technical staff of Gansu Huaduo Agricultural Science and Technology Co. , Ltd. told us how to manage the peony blossom meeting

Do you want to trim the peonies after they blossom?

After the Peony Blossom, the first task is to cut off the residual flowers, when pruning and has been formed with the pod cut, so that the peony nutrients will not be lost, the nutrients concentrated in the root to promote better growth of branches.

A lot of hobbies want to keep the seeds mature after sowing, a lot of double peony knot seeds will not germinate, even if the germination will not open a beautiful flower, because the seeds out of the peony changed a lot.

Second, it needs pruning to grow new branches from the roots

In addition to pruning the residual flowers, we should also pay attention to cutting off the foot buds that sprout at the root in time, as well as some diseased branches and overdense branches, and remove the lower aged leaves in time for ventilation and ventilation, reduce nutrient consumption to prevent the breeding of pests and diseases.

Three, what else do you have to do besides trim?

Post-flowering pruning is only one aspect, we have to strengthen the management of this relatively mild season after the flowers. First of all, we can simply use some organic fertilizer, decomposed mixed with some compound fertilizer, which can restore vitality, and can promote the growth of peony.

Again with fertilizer, can be appropriate watering, peony flowers do not like too much water, its roots fat, too much easily rotten roots, maintain the soil dry on the line.

The newly transplanted trees need to be protected from the Sun to prevent evaporation from high temperatures in the summer.

In order to protect the leaves from diseases, Bordeaux mixture or 200-fold carbendazim suspension should be sprayed every 7-10 days after flowering for 2-3 times. This can make the leaves less damage throughout the year, so that photosynthesis can be normal, for the next flowering accumulation of more nutrients.

Peony Flowers to bloom, spring management is very important, teach you a few management skills

 The temperature gradually rose in spring, peony also began a year of growth recovery, peony spring care is directly related to the growth and flowering of the peony

Flowers, then, how should Paeonia suffruticosa be managed in the spring? Next for everyone to introduce the peony spring maintenance management points.

First, spring peonies need a little pruning

Peony flowers, to the spring, as the weather is warming, its bud has appeared, at first looked small, but can already be recognized, at this time we should pay attention to a little pruning, pruning mainly to complete the following tasks, first, we should trim the dense branches to improve the light, and second, we should cut off the dense flower buds. After all, peony flowers consume too much nutrients, if the flower buds are too much, it will lead to too much nutrient dispersion, peony flowers are relatively small, loss of aesthetic appeal.

In spring, the peony will sprout more soil buds from its roots. Some friends will say, isn’t this a good thing? Don’t you get more young peony plants? In fact, this understanding is wrong. Most peonies are obtained through root grafting of Paeonia lactiflora pall. The soil buds from the root system can not produce dainty peonies, and they compete for nutrients. These are very disadvantageous to peonies, so you have to get rid of it in time.

Second, the peony flowers to the spring should be timely fertilization and watering

The peony flower will bloom in the future, and the consumption of nutrients is relatively large. After a long winter, the peony flower has already consumed more nutrients, so it is very necessary to supplement nutrients in time, in other words, we should fertilize Paeonia suffruticosa in time. We should fertilize peony flowers. We should pay attention to the use of decomposed organic fertilizer, such as decomposed cake fertilizer, decomposed animal waste, etc. . These fertilizers have stable nutrients, can improve soil fertility, more importantly, can improve the quality of peony flowering, bloom in the future, let the flower color more charming.

Use decomposed organic fertilizer at the same time, we can use compound fertilizer, let the inside of the nitrogen element to promote growth, inside of the phosphorus and potassium elements to promote flowers, at this time absolutely can not partial fertilizer nitrogen fertilizer, partial application of nitrogen fertilizer will lead to excessive growth of nutrients in peony flowers, weaken the growth and growth, the flower bud can not get such elements as phosphorus and potassium breeding, will make the flower bud thin and weak, and even will disappear.

If we want to make better use of the fertilizer effect, we should also pay attention to reasonable watering. We should not water too often, otherwise the fleshy roots of peony flowers are easy to be soaked and rot, when watering should wait for the soil to become dry two or three centimeters again water is not late, water must be watered thoroughly.

Third, the peony to see more sunlight, pay attention to ventilation loose soil

If the peony flower wants to blossom in spring, it must pay attention to give it more moderate sunlight. The sunlight in spring is very mild, which is good for the peony flower to carry out photosynthesis, to make more nutrients, and is good for the plumpness and expansion of the bud, if potted peony, it should be placed in a well-lit place, in addition to pay attention to timely ventilation, so that peony growth can be more state.

The root system of peony is fleshy root, not water stain, like to breathe, so you can loosen the soil, loose soil, peony root system will be very good breathing and relaxation, absorb more nutrients, to promote plant growth.

How a seed of Paeonia rockii grows into a tree peony

 Peonies are giants in the peony world. They are tall, fragrant and resistant to cold. The main methods of propagation are grafting and fruiting. How does a seed grow from a seedling to a tree

Choose the full-bodied seed of peonies

1. Before sowing, Soak 300 times of thiophanate-methyl solution for 30 minutes to sterilize, remove and place in a cool place to dry

2. If the area of seedling is large or the condition is allowed, the sowing machine is usually used or the artificial sowing can be adopted. If it is a mechanical sowing, be sure to level the ground to avoid local sowing too deep.

The sowing quantity is 90-100kg/Mu, the sowing depth is 3-5cm, the row distance is 20-25cm, the concrete also has the relations with the local climate and the soil condition.

Every 4 rows is a ridge (bed) covered with a layer of 120 cm plastic film, film is too wide central seedlings easy to rot, not easy to survive.

3. After mulching plastic film covered with grass or a sm

all amount of soil, to increase the temperature, extend the growth time of new roots, is conducive to the next year strong seedlings. Early Spring Peony shoots drill out before the ground, to remove timely plastic film.

The space between small Ridge (bed) and small Ridge (bed) is 40cm, which is convenient for later watering and pipe protection.

4. The seeds of Paeonia rockii germinate after three months and take root in the following spring

It takes at least six months for a seed to be planted and a young tree peony to form. It is this young tree that has been honed into a big tree through decades of continuous growth, to be a giant in the peony kingdom.

 

How to plan planting Paeonia Rockii in autumn

 Start of autumn, one of the solar term, is an important solar term in the Chinese calendar.  is the first solar term of autumn, is a sign of the beginning of autumn. After the beginning of autumn, when the heat is gone and the fruits are fragrant, the scenery is especially enchanting. This is also the best planting time for Peony. So how to plan the planting of paeonia rockii Peony in autumn,

1. Choose the right place to grow

Personal farming

First of all, we must choose the place where our own yard is planted, the peony growing environment, because it likes warm, cool and dry places, but also like the sun, can fight the cold, fight the drought, so it is relatively simple, the flowers can be planted, and in the flower farmers planting time must choose more loose soil, the best drainage is better place to plant.

Large-scale cultivation

The newly reclaimed land is often turned up to about 60 cm deep and fully weathered, and 45,000-60,000 kg of organic fertilizer is applied per hectare. When preparing the ground, make a 1.5-meter-wide bed with turtle-shaped surface and open ditches to allow drainage. Saline-alkali land, clay land or land with high water table are not suitable for planting.

2. Fertilize properly

Peony is like fertilizer flowers, especially nitrogen, phosphorus, potassium and other elements more complete fertilizer, such as chicken, pigeon, rabbit, earthworms, pigs, dogs, cattle, sheep manure and other organic fertilizer. But it has to be rotted before it can be used. UNRIPE, fertilizer, fermentation breaks down an organic acid, which causes the roots to rot. In the city can use fresh water fish miscellaneous, chicken miscellaneous, broken bones, the first such as water retting system rot after application.

3. Learn farming techniques

The plant depth is 30 cm deeper than the root of the original plant. At the bottom of the pit, put some decomposed organic fertilizer and chemical fertilizer into the soil and stir them thoroughly to ensure that the new roots can absorb the fertilizer in time.

When planting, root system should be evenly distributed in the pit, natural stretch, can not be curled together, fill with live soil will be buried root system first, and then, the seedlings gently shake up. First, the root system should be fully integrated with the soil. Second, the planting depth (the planting depth should be lower than the original root neck about 3 centimeters above the ground) should be determined. First step the first time, then fill the soil and then step the solid soil, when the plant is finished, should be timely watering a pervious, in order to discharge the air in the soil, to prevent the winter cold root injury.

Why Autumn is one of the best seasons for transplanting peonies

Spring is the season of peony branch

Summer is the dormant period of peony, high temperature season, the above-ground part into the stage of flower bud differentiation and seed development, when the root activity becomes weak, in a semi-dormant state.

After autumn, as the temperature drops, the root system of tree peony begins to grow a second time, it will grow a lot of capillaries, a lot of nutrients in the root bark (mainly secondary phloem) in the accumulation. At this time, the above-ground part of the branches and leaves slowly withered into the dormant period, but the peony root system is still growing to produce new roots. These new fine roots is the most important tree peony transplant, transplant to other places, can adapt to the new environment, quickly take root, so safe over the winter.

What are the benefits of transplanting peony in autumn?

The temperature drops gradually when peony transplanting in autumn, the above-ground branch enters dormancy period, the leaf slowly withers this to the water demand is little, consume nutrient little, this is advantageous to the nutrient balance. Moreover, at this time, the root bark was rich in nutrients, and the ground temperature was relatively high even though the outside temperature had not yet dropped significantly.

The roots of the tree peony were not yet completely dormant, and the root system cut off during transplantation could be healed as soon as possible, and the root system is still growing, constantly producing new roots.

How much do you know about paeonia rockii ? Let me show you some peonies in Gansu

In the northwest of China, such as Gansu, Qinghai, Shaanxi and Ningxia, there is a long history of northwest peony species, the wild original species of this species called Paeonia Rockii, also known as Gansu Peony. It is a large deciduous shrub of the genus Ranunculaceae, so named because it has a distinct red, purple, or black spot at the base of the petal. It is also known as Gansu Peony and northwest peony because its wild species are distributed in the south-central area of Gansu Province and the West Qin Mountains primeval forest at 1300 ~ 2800 meters above sea level at the junction of Gansu, Sichuan and Shaanxi.

In the broad natural environment of northwest China, the bold and unconstrained style of Gansu purple-spotted Peony is bred, which forms a temperament quite different from Central Plain and Jiangnan Peony.

One is big, tall and conspicuous plant. Paeonia ROCKII whole plant height can reach 3 meters, crown width also has 3 ~ 4 meters, it has "peony giant" said. Compared with other tree peony varieties, the purple-spotted tree peony is called "big brother" .

The second is pretty face, gorgeous fragrance of flowers. Peony flowers in the flowers, purple-spotted peony flowers and particularly outstanding, its petals texture thick, fine, fresh, large flowers, up to 25 cm in diameter, flower-rich, clear-cut, female, stamen changes a lot, so very rich ornamental value. In particular, the flower of peonies is particularly strong, peonies in Central Plain.

Third, the resistance is strong, drought-resistant, cold-resistant, barren resistance. Paeonia ROCKII is a shade-tolerant plant, which likes to grow in the sparse shrub on shady slope or in the weak light, bare rock and barren soil in the forest under cliff. Its root system can reach more than 10 meters underground, so it has a strong drought resistance, especially the ability to withstand air drying is very strong, in the case of severe drought, it can still grow and bloom; the Soil Adaptation Range is also larger, from slightly acidic to slightly alkaline, can grow normally. In addition, Paeonia Rockii is a cool and dry ecological plant, can be in-40 °C outdoor low-temperature environment, without artificial protection can be safe winter, very suitable for cold areas cultivation.
