　　Use seeds to propagate. The type of seed maturity. After the seeds are ripe and harvested in early May, choose a cooler and smoother hillside with branches to build a shelter. Rainwater can naturally pour into the shelter, dig 20cm deep as a cellar, and store the seeds and wet sand in the cellar layer. After morning and evening and low temperature in autumn.

　　The embryo gradually developed and formed. From October to November, the seeds are sown in Gaoqi after splitting, and the seeds are sown 22.5~37.5kg per 1hm2 and covered with cow and horse dung. In the second half of February of the following year, a short shed was placed on the border surface to shade. Seedlings emerged in early March, and the border surface leaves were removed, and weeds were removed. During the seedling period from May to June, quick-acting nitrogen fertilizer should be applied to catalyze the seedlings, and the fine crushed cow dung and fire ash humus should be sprinkled between October and November to facilitate the winter.

　　Traditional planting technology adopts tent shading. In winter, the trees are cut to build a 1.2m high shed, with a shading degree of about 70%. The shed is made of 1.6m wide high border (box). In the third year and March after planting, the seedlings in the nursery have been transplanted when they have grown 4 to 6 true leaves. The plant spacing is 10cm×10cm, the planting depth is 3 to 5cm, and 75 to 900,000 plants are planted per 1hm2. It is useful for intercropping corn and forest planting techniques. In winter, bushes such as hemp and mulberry and trees such as pine and cedar are planted at intervals of 1.6m on the border surface. In early spring at the end of February, corn seedlings were cultivated in a plastic shed as a nutrition bowl.

　　When the seedling height is about 30cm, the corn seedlings are transplanted at a plant spacing of 30cm on both sides of Gaoqigou, and the leaves are directed to the leaves. After the corn leaves are sealed in June and July, the Coptis chinensis is planted between the rows. After the winter corn is harvested, weave a short shed with corn stalks to shade the Coptis chinensis. The corn was replanted the following year, and the shrub had become a forest about 4 to 5 years later, and it could be shaded by Coptis chinensis, and no more corn was planted.

　　After the Coptis chinensis is harvested, it will be prepared in the forest, with plantar fertilizer, and it can be replanted. After the shrub forest is planted with Coptis chinensis for 2~3 seasons, the trees have become a forest, and then the shrubs can be felled and planted under the arbor forest. The use of corn and afforestation and shading techniques to plant crops not only does not affect the yield of Coptis chinensis, but also saves labor, materials, and investment, and the amount of standing trees is twice as fast as the forests without Coptis chinense.
