What are the planting techniques of white fresh bark?

White fresh bark, also known as mountain peony, eight strands of cattle, is a more common heat-clearing and detoxification medicine, the cultivation value of white fresh bark is relatively high, so many people are planting. So what are the planting techniques of white fresh skin?

I. Land selection and land preparation

White fresh bark is generally propagated with seeds, first centralized breeding, growing for one to two years before separate planting. To raise seedlings, we should choose sandy loam flat bottom or gentle slope with sufficient sunshine, loose soil quality and good drainage. Saline-alkali land and heavy-year land should not be selected, and there should be conditions for drainage and irrigation. Generally choose 25 to 30 centimeters of deep ploughing, and then choose the mature farm manure according to the fertility. When transplanting, choose gentle slope land with good drainage, which can be planted in hillside wasteland, orchard, artificial young forest and other places.

2. Sowing and transplanting

White fresh bark usually waves from mid-April to early May. When sowing, hold the flat bed and trench at a distance of 12 to 15 centimeters. The trench can be 4 to 5 centimeters. After stepping on the bottom grid, sow the seeds and fine sand together and cover with 4 to 5 centimeters of soil. If possible, straw can be added to moisturize. After growing for 1 to 2 years, the seedlings can be transplanted after the ground has withered in autumn or before turning green in spring. When transplanting, dig up all the seedlings and transplant them according to size, with the top bud facing up to stretch the root of the seedling. The soil should be 4 to 5 centimeters below the top of the bud, and should be watered thoroughly in case of drought.

III. Daily management

1. Light and water source: White fresh bark is generally grown in the sunny hillside, low bushes between the sandy soil, its adaptability is relatively strong, like warm and humid places, like light. Can withstand cold and drought, not resistant to waterlogging.

two。 Weeding: White fresh bark in the first two years of transplanting, see the grass should be removed, need to weed 3 to 4 times a year, after 3 years of plant growth is higher, the effect of grass on seedlings is relatively small, can reduce weeding.

3. Fertilization: White fresh bark should be fertilized twice from late May to early June, each time with farm fertilizer or urea, and then the Beginning of Autumn was sprayed with 0.3% 0.5% potassium dihydrogen phosphate foliar fertilizer once.

4. Pest control: White fresh skin common diseases and insect pests are downy mildew, Sclerotinia sclerotiorum, rust, yellow butterfly and so on, need to spray corresponding pesticides according to the actual situation.

IV. Harvest

White fresh bark grows for 2 to 3 years after transplanting, and the roots are harvested after the aboveground part of the plant has withered in autumn or before turning green the next spring. First cut off the stems and leaves on the ground, and then dig out all the roots from one end of the seedbed, removing the soil and the remaining stems. Remove the fibrous root when it is dried in the sun, extract the xylem in the middle, and store it in the storage after it is fully dried. Generally speaking, 300 to 350 kilograms of fresh white skin can be produced per mu.

The cultivation and daily management of white fresh bark are relatively simple, and the receipt of planting is also considerable, which can be planted in large quantities.
