Embodiment Construction

[0013] The technical scheme of the present invention is further described in detail below through the examples, but it is not limited thereto.

[0014] A method for cultivating rhubarb Codonopsis in rotation, comprising the following steps:

[0015] ⑴In areas with an altitude of 2000-3000m, choose neutral or slightly alkaline semi-sunny fields, which require deep soil layers, rich in humus, and sandy loam with good drainage;

[0016] (2) Harvest the seeds of three-year-old rhubarb plants that are free from diseases and insect pests and carry out spring seedling cultivation. Transplant them into the selected field from March to April of the second year, and plant them in holes with a row spacing of 45cm×60cm. The depth of the holes is 35cm. After the seeds mature in July of 3 years, they are excavated;

[0017] (3) Codonopsis pilosula seedlings were raised on the shady slope in the second year of rhubarb transplanting, and Codonopsis pilosula seedlings were transplanted in the...

Abstract

The invention provides a rotation cropping method for rheum officinale and radix codonopsis, and relates to the field of planting of traditional Chinese medicine materials. A neutral or slight alkaline half-sunny slope farmland which is suitable for growth of the rheum officinale and the radix codonopsis is selected in a region with the altitude of 2,000-3,000 m, time is arranged reasonable, alternate rotation of the rheum officinale and the radix codonopsis is carried out in the same land parcel, continuous planting of the traditional Chinese medicine materials is realized, the output value in unit area is increased remarkably, the economic income of farmers is increased, the planted medicinal materials are diversified, and adjustment of the traditional Chinese medicine material industrial structure is facilitated.

Description

technical field [0001] The invention relates to the field of planting Chinese medicinal materials, in particular to a method for cultivating rhubarb and Codonopsis pilosula in rotation. Background technique [0002] Tangut rhubarb is one of the cultivars of the genus Rhubarb. It has strict requirements on the soil. Generally, loam or sandy loam with deep soil layer, rich in humus, and good drainage is better. Tangut rhubarb likes cold and cool climates, is cold-resistant, and avoids high temperatures. It is more suitable for planting in areas with an altitude of 2000-3500 meters. When planting, continuous cropping is avoided. After harvesting, it needs to be replanted after 4-5 years. [0003] Suhua Codonopsis, Platycodonaceae, Codonopsis genus, originates in mountainous forests and shrubs at an altitude of 1560-3100 meters in northern China. It is distributed in northwest Sichuan, Qinghai, Gansu, southern Shaanxi and central Shanxi in mainland China. Cultivation in sandy l...
