Embodiment 1

[0028] A kind of rotation ecological planting method of Coptidis Rhizome, Hubei Fritillaria, and Sichuan Codonopsis, the specific steps are as follows:

[0029] (1) In May 2003, at the Coptidis Coptidis planting base in Liziba Village, Shazi Town, Shizhu County, Chongqing City, the Coptidis Coptidis cultivation method was carried out according to the conventional Coptidis planting and cultivation method; the specific steps are as follows: in step (1), the Coptidis Coptidis cultivation method specifically includes Seedling raising, transplanting, fertilization and field management;

[0030] For the seedling cultivation, apply 500-1000 kg of decomposed manure per mu before seedling cultivation, or apply 100 kg of phosphate fertilizer per mu. Apply 12kg of urea as topdressing, and sprinkle 150kg of sieved humus soil on the side of the car per mu; from October to November, sprinkle 500-1000kg of dry manure per mu on the seedbed; in the spring of the third year, apply urea per mu ...

Embodiment 2

[0044] In addition, because crop rotation can effectively improve the physical and chemical properties of the soil and adjust soil fertility, Coptis chinensis will continue to be planted in the land where Codonopsis pilosula is harvested after the rotation. The yield and pest damage of Coptis chinensis are shown in Table 2.

[0045] Table 2. Coptis chinensis production and statistics of main diseases and insect pests

[0046] Types of herbs

[0047] The results showed that Coptis chinensis can be planted directly on the land after crop rotation, which solved the problem that the yield of Coptis chinensis was greatly reduced or even failed after heavy cropping.

Abstract

The invention discloses an ecological planting method for crop rotation of coptis chinensis, Hupeh fritillary bulbs and codonopsis tangshen. The method particularly comprises the steps that a land used for planting coptis chinensi is ploughed and dried in the sun, then one part of the land is used for seedling raising of codonopsis tangshen seeds, the other part of the land is used for planting the Hupeh fritillary bulbs, and after the Hupeh fritillary bulbs are harvested, seedlings of codonopsis tangshen are transplanted into the land where the Hupeh fritillary bulbs are planted. The ecological planting method for the crop rotation of coptis chinensis, Hupeh fritillary bulbs and codonopsis tangshe has the advantages that crop rotation cultivation is conductive to the balanced use of soilnutrients and the prevention of diseases, insects and weeds; the physical and chemical properties of the soil can be effectively improved, and the fertility of the soil is regulated; the method is simple and easy to operate, has operability and popularization, and meets the requirements for sustainable development of the planting and cultivation of the three Chinese herbal medicine materials of coptis chinensis, Hupeh fritillary bulbs and codonopsis tangshen.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for ecological planting in rotation of Coptidis Rhizome, Hubei Fritillaria, and Sichuan Codonopsis. Background technique [0002] Shizhu County, Chongqing City is the original place of origin of Coptis chinensis and the well-known "Hometown of Coptis chinensis" in China. It has unique geographical and natural conditions. More than 30,000 peasant households in the county plant Coptis chinensis, maintaining more than 50,000 mu of Coptis chinensis all year round, with an average annual newly planted and harvested area of ​​10,000 mu of Coptis chinensis, with an output of about 1,800 tons, accounting for about 60% of the country and 40% of the world. During the process of planting Coptis chinensis, there are serious barriers to continuous cropping, and the yield of Coptis chinensis is greatly reduced or even completely lost after repeated cropping. Therefore, ...
