Medicinae intercropping intercropping high-yield cultivation techniques

Peony is a valuable Chinese herbal medicine, which has a long growth cycle, high yield, and stable economic benefits. In recent years, the market demand has been continuously increased. In order to improve economic efficiency, the Bozhou City Institute of Medicinal Herbal Plants has successfully planted peony for many years. Intercropping of crops is a new technology that is promoted across the country. The methods are as follows.

First, nursery method

Peony is usually transplanted with seedlings and seedlings. It is advisable to raise the seedlings from August to December. The peony is usually drilled in a row, with a 10- to 15-centimeter row spacing and a 3- to 4-centimeter-depth ditch at a spacing of 5 to 7 centimeters. The seed is seeded in the ditch and then covered with a damp layer. The fine earthworms were flattened and slightly repressed, and then covered with a layer of 5- 10-cm thick wheat straw to protect the seedlings. The seed was used at 50--60 kg per 667 square meters. After the second year of thawing, cover grass is removed between “rainwater” and “convulsions”. When the seedlings reach about 80%, they can be sprayed on the stems and leaves of the seedlings with a 1:200-fold Bordeaux mixture. Disinfect seedbeds and promote root growth for transplanting in the autumn.

Second, transplanting method

Peony is generally transplanted from September to November, and is planted in rows of 45-55 cm spacing and 35 cm spacing. In order to increase the yield, two trees can be planted in each pit. The method is to separate the two seedlings slightly in one hand, and fill the pits with the other hand. When the soil fills the pit, the seedlings are raised slightly to make the roots straight. The top buds should not exceed the ground, then fill the soil around the seedlings, compact and cover the soil 10 cm thick for winter.

Intercropping

The peony grows slowly for the first 3 years. In order to make full use of the land for income increase, intercropping with intercropping has provided considerable economic benefits. In the first two years, cotton can be interplanted, and each peony is planted with one row of cotton in each row. The cotton spacing is 40 centimeters. Every two rows of peony leaves a working path to facilitate cotton fight and trim. Interplanting cotton is the same as professionally growing cotton. Soybeans, corn, vegetables, and other herbs are interplanted with cotton. The peony dormancy period is from early July to mid-February. Double-row interplanting does not affect each other. It can also be planted in the second year, which is half the density in the first year. The third year for the peony flowering period, can be seeded 130 - 160 kg. The end of the fourth year of the end of the seeds up to 200 kilograms, at the same time can be harvested rhizome medicine, per 667 square meters can be produced Peony dry goods 550 - 650 kg.

IV. Pest control

Peony is basically free of pests and diseases throughout the growing season. If leaf spot disease and root rot are found, reference can be made to the prevention and treatment of fruit trees.

V. Harvest processing

After peony is transplanted, it is generally 3-4 years old. From August to October, it will be dug, roots will be shaved, net soil will be removed and placed in the room. After a few days, the roots will become soft and easy to pull core. After the core-pulled peony is dried for medicinal purposes, it is commonly known as Heidan Pi, and some of them are scraped off with a glass piece to remove the outer skin, and then the core is dried and dried. The kernels are thick, thick and long without wood cores, and the cross section is white and white, with a strong scent.
