Field management of white peony, planting method of white peony

Cultivating and weeding: Cultivating and weeding 3 or 4 times a year when peony is first planted, the first time is in spring after the seedlings, it should be shallow; The second time was in the summer when weeds were abundantly grown, which was slightly deeper than the previous time; The third time is in the autumn after the seedlings are poured.

After planting, the number of weeding can be reduced to 2 times, the first in spring and the second in early summer. Drying roots: In order to concentrate nutrients on the main root of peony and increase the yield of medicinal materials, starting from the second year after planting, from late March to early April every year, the soil of the roots of peony is peeled off, so that half of the roots are exposed, dried for about 1 week, and then covered with soil and compacted.

Top dressing: Peony likes fertilizer, in addition to applying sufficient base fertilizer, from the second year after planting, it needs to be topdressed 2 3 times a year. In the first half of April, combined with the drying of roots, 1000 2000 kg of manure and water of ripe and mature humans and animals were applied every 667 meters; 5 In July, combined with cultivating weeding and then topdressing once, 1000 2000 kg of decaying human and animal manure water was applied every 667 meters; 11 After returning to seedlings in December, apply 2000 kg of decomposed manure or compost every 667 meters, add 30 kg of cake fertilizer, apply in the ditch between the rows, cover the soil after application, and water thoroughly.

Flower buds: In order to concentrate nutrients for root growth, the flower buds are removed in time when the buds appear every spring, starting from the second year after planting. Drainage irrigation:

Peony likes dryness, has strong drought resistance, and only needs to be irrigated in severe drought; Peony is afraid of moisture, but also afraid of stagnant water, often because of the soil moisture content and rotten roots, in the rainy season to remove the field water. Soil cultivation: In late October until the soil freezes, cut off the withered branches and leaves of the aboveground part of the peony at a distance of 6 9 cm from the ground, and cultivate soil at the rhizosphere for 10 15 cm to protect the peony buds for safe wintering.

Pest control: The main diseases of peony are gray mold, leaf spot and leaf mold. In the early stage of the disease, 50% carbendazim 800 1000 times solution was sprayed, once every 10 days, sprayed 2 3 times; Or spray 1 1 100 Bordeaux liquid, every 10 14 days, spray 3 4 times.

In the early stage of leaf spot disease, spray 50% carbendazim 800 1000 times solution, 50% thiophanate-1000 1500 times solution or 1 1 100 Bordeaux solution, spray once every 10 days, spray 2 3 times. After the germination of peony and before flowering in late April, spray 50% carbendazim 800 1000 times, 50% thiophanate-1000 times or 65% zinc 500 times, once every 10 days, spray 2 3 times. The insect pests of peony are mainly grubs, and every 667 meters before ploughing with 250 300 liters of 50% phoxanthion emulsifiable concentrate or 300 350 ml of BT emulsion, moistening 10 15 kg of fine soil to make poisonous soil, evenly sprinkled on the surface; Or apply the prepared poisonous soil directly to the planting hole.

In early to mid-May, the adult worm peak period can be sprayed with 1500 times of 40% dimethoate emulsion and 80% dichlorvos emulsion, and 100 kg of liquid medicine per 667 meters; It can also be sprinkled with dimethoate powder and trichlorfon powder kilograms per 667 meters.

Loosen soil in early spring to protect moisture, after the emergence of seedlings 4 times a year in weeding, combined with hoeing in the root soil, in late October, before the ground freeze in 7 10 cm from the ground to cut off the branches and leaves, rhizosphere soil about 15 cm, in order to facilitate wintering. From the second year, fertilization is applied 3 times a year, respectively in late March and early April, dilute human feces and urine, the second time in late April, 500 kg of human manure per mu, and the third time in October and November, mainly circle fertilizer, 1500-2 000 kg per mu. Top dressing 2 times before harvest in the fourth year, and it is advisable to open holes on both sides when topdressing.

Peony generally does not need irrigation, severe drought, should be irrigated in the evening 1 permeable water, rainy season, should be drained and irrigated in time, every spring when the buds are taken off in time.

White peony, also known as white peony, has hypertrophied roots, straight and smooth stems, and has been planted in China for a long time, and is a very important Chinese medicinal material. White peony is suitable for growing in a warm and humid environment and has cold-tolerant properties. It begins to grow vigorously in April and May every year.

White peony is generally planted in a soil with fertile, ventilated and breathable soil, and a good drainage system is required for large-scale planting. Before planting, the size of the bud head is distinguished and planted separately, which can ensure the neat growth and facilitate management.

In early spring, the land will be loosened, weeded according to the situation after the emergence of seedlings, and the appropriate implementation of soil cultivation on the roots of Danhui, in the early winter period, the ground will be frozen before the branches and leaves of about 10 centimeters from the ground will be removed, and the soil will be cultivated again, which is conducive to the white peony to survive the cold winter. From the second year onwards, fertilize it in March and April, respectively, and human feces and urine are the best. The amount of application per mu is selected according to the actual situation, and during November, you can carry out circle fertilizer, and increase the amount of fertilizer per mu.

After that, fertilize twice before harvesting. Remove the excess flower buds every year and irrigate them appropriately.

It is inevitable that insect pests will be encountered during the planting of white peony, so it is necessary to remove the diseased branches and leaves and spray a certain amount of drugs for control. The medicinal value of white peony is very high, the harvest period is generally in the fourth year after planting, the rhizome is cut off, and then the roots are dug out, leaving the part of the seed, and the rest can be used as medicinal materials in the sun.

Summary. The planting technology of white peony Before planting white peony, you can first divide the bud roots of white peony into two kinds according to the size, open the hole when planting, the row spacing is generally forty to forty-five, and the plant spacing is about 30 centimeters.

2.White peony sowing time The sowing time is generally mid to late September, and it can be sown by strip sowing method. The amount of seeds per mu is about 30 to 40 kilograms, and when the seedlings come out, the cover grass should be uncovered in time. The new production period of white peony is usually in July and August.

Peony is suitable for warm and humid climate conditions, and likes sunlight, temperature, fertilizer and certain cold tolerance. It grows well under the conditions of 14 5 per year and 27 8 per month in July.

Peony is a perennial root plant. The soil germinates in March every year, April and June is the period of vigorous growth and development, the flowering period is May, the fruiting period is June and August, and the aboveground part begins to wither in mid-August, which is the period when the content of peony glycosides is the highest.

The seeds of peony are epicotyl dormant type, which takes root in the same year after sowing, and then breaks the epicotyl dormancy after a period of low temperature, and breaks the soil and emerges the seedlings in the next spring.

Paeonia alba, perennial herbaceous or subshrub, lumpy or thick in the underground; leaves basal or stem-born, large, alternate, pinnate or triple-out compound or deeply lobed; The flowers are large and beautiful, solitary at the tops of branches or sometimes in bunches, white; sepals 5, suriant; petals 5 10, but often double petals in cultivated species; stamens majority; flower disc ring-shaped or cup-shaped; The carpel 2 5, centrifugal development, when fruiting becomes follicles, each with several seeds. Grows in bushes or grasses on hillsides and valleys. It is planted in most parts of the country.

Peony is cold-tolerant, likes fertilizer and is afraid of waterlogging, likes moist soil, but is also drought-tolerant, likes sunshine, and likes cool climate in summer. Potted peonies are easy to scorch the leaves under the scorching sun in midsummer, and should pay attention to shading. Peony is a fleshy root with a long root system, so it should be planted in a fertile and loose, well-drained sandy loam soil, and planted in clay soil and low-lying waterlogged places that are prone to root rot.

Peony can not be transplanted often after planting, otherwise it will damage the roots, affect growth and flowering, in order to make peony grow well, it is necessary to carry out reasonable fertilization every year. Potted peonies, cut off the wilted branches and leaves after the frost falls, to prevent breeding of diseases and insects. During the wintering period, there is no need to move indoors, just place it on the balcony or in a sunny place under the eaves, and the potting soil should not be too dry.

More and more people are beginning to grow white peony, and its cultivation technology is particularly important. White peony likes water and sun, so it is generally planted from August to October, in a place with sufficient sunshine, deep and fertile soil, and ventilation. Before planting white peony, 25 to 40 cm ploughing should be carried out 1 to 2 times, and 2000 to 4000 kg of fertilizer per mu should be applied as base fertilizer.

The row spacing of white peony planting can be 55 to 25 cm, about 3500 to 4000 plants per mu, and 1 to 2 bud heads can be placed in each hole, and then landfilled. Let's talk about it in detail.

1.The planting environment of white peony:

White peony likes water and sun, so it is generally best to choose a place with plenty of sunshine, deep and fertile soil, and ventilation for planting. The roots of white peony are particularly deep, so before planting white peony, it must be carefully cultivated, and the depth of ploughing is required to reach 25 to 40 cm, and the ploughing must also reach 1 to 2 times, and 2000 to 4000 kg of fertilizer should be applied to each mu as base fertilizer.

2.Cultivation method of white peony:

White peony is generally planted from August to October, and if it is planted too late, the bud head of the white peony will send out new roots, which will be particularly easy to break and cause a lot of loss, and the growth of the white peony will also be affected badly in the second year.

When planting white peony, it is best to plant Zhaozhou cover separately according to the size of the white peony garlic. The row spacing of white peony planting can be selected as 55 25 cm, about 3500 to 4000 white peony plants can be planted per mu, and 1 to 2 bud heads can be placed in each hole in the ground, and then landfilled, to be buried into the shape of a small pile.
