Prevention and control of diseases and insect pests: powdery mildew is controlled with stone-sulfur mixture, insect pests such as grubs and mole crickets are trapped and killed with poison bait. Mu income: per mu of dried Coptis chinensis rhizome product 100kg, the price is 115yuan / jin, mu income is 23000 yuan.

First, select the woodland

It is necessary to select woodland with large shade, Sijiqing with no deciduous leaves all the year round, dwarf trees with a height of about 3.3 m, and artificial fir woodlands with a slope of 20 °- 25 °. It is better to choose soil rich in organic matter, humus, upper and lower fruit, but not clayey dead yellow mud and white eel soil.

Second, tidying up the shadow shed

For the natural forest, it is necessary to cut down all the dead branches, thatch and small trees of the woodland, leave the shrubs and dwarf trees, and remove the twigs less than 2 meters from the ground, and the shade degree should be kept between 70% and 80%. Generally, for the artificially cultivated Chinese fir forest, it is necessary to choose the young woodland, basically to connect the branches, and in some places, if there is a skylight, you need to insert branches around Coptis chinensis, which is conducive to shading.

Third, prepare the land and make beds.

1. Before soil preparation, the fallen leaves, residual branches and stones on the topsoil need to be raked out of the forest, and the bamboo roots, small tree roots and thatch roots in the forest should be removed. At the same time, pay attention to not causing damage to the tree roots and not digging deeply when digging the ground.

2. For the artificially cultivated Chinese fir forest, only one shallow dig is needed, and then the weed roots and stones are picked out. If there is no soil around the tree, the soil needs to be cultivated, so that the roots are exposed outside, and then the ditches are made, straight ditches are made from top to bottom, the ditches are 23cm in width and 10cm in depth, and the soil at the bottom of the ditch is lifted on both sides of the border.

IV. Transplanting

Generally, Coptis chinensis seedlings planted under the forest need to choose 2-year-old seedlings with more than 12 leaves. If it is evergreen and coniferous woodland, Ching Ming Festival can transplant, while broad-leaved woodland needs to wait until the leaves grow new leaves for transplanting.

V. Prevention and control of diseases and insect pests

The main diseases of Coptis chinensis are powdery mildew, which needs to reduce shade degree, increase light appropriately, and can be controlled by stone-sulfur mixture at the same time. Insect pests are mainly grubs and mole crickets, and poison baits can be used to kill flowers and seeds. In early spring, suede and pheasant are harmful to flower moss and seeds. Fences are needed to strengthen artificial hunting, which is helpful to reduce the disease.

6. Income per mu

1. Coptis chinensis can not be harvested until the fifth year after transplanting, and it is a kind of medicinal plant with long growth years. The suitable harvest time for Coptis chinensis is before freezing in early October and late November. Generally, Coptis chinensis can be dug out according to the row spacing with four-toothed Harrow.

2, then cut off the whisker root and leaves, each mu can produce about 500kg fresh roots, fresh roots unearthed, can be dried with Kang, drying should not be too large, while turning over, until dry, generally dry Coptis chinensis rhizome finished product 100kg per mu, the market price is 115yuan / jin, mu income is 23000 yuan.
