Cultivated land cover seeding method of pilosula var. modesta

Abstract

The invention discloses a cultivated land cover seedling method of traditional Chinese medicine of pilosula var. modesta, relates to the technical field of planting of the traditional Chinese medicines, and belongs to the seedling method of the pilosula var. modesta. The cover seeding method is characterized in that seeds are evenly sown on land surfaces which are then covered with a layer of cultivated land soil about 0.3-0.5mm in thickness, and the soil is pressed slightly; after sowing, the soil is immediately covered with wheat straws with 0.4-0.6kg / m2, and seedlings are subjected to final singling when growing to 4-6cm in height. The cover seeding method has the advantages that pest and disease damage is effectively alleviated through soil treatment and soil treatment, and uncultivated land seedling of the pilosula var. modesta is replaced by the cultivated land seedling; water conditions of soil surfaces can be improved through ground coverage, survival rate of the pilosula var. modesta can be effectively increased, production cost can be reduced, production scale of the pilosula var. modesta can be enlarged, and pharmaceutical supply can be guaranteed. As is tested that the cultivated land cover seeding method can effectively reduce production cost, and rate of emergence can be averagely improved 43%.

Description

Technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, and belongs to a method for raising seedlings of the plain flower Codonopsis pilosula, in particular to a method for growing seedlings of the plain flower radix codonopsis covered with ground. Background technique [0002] Codonopsis pilosula is the dried root of Codonopsis pilosulaNannf.var.Modesta (Nannf.)LTShen). The medicinal product is called Codonopsis pilosula. Its base plant is called Codonopsis pilosula, which is part of Codonopsis pilosula. Boutique. Codonopsis pilosula is an authentic medicinal material in Wenxian County, Longnan City, Gansu Province. In August 2008, the General Administration of Quality Supervision, Inspection and Quarantine of Gansu approved the use of Codonopsis pilosula as a "geographical indication product" and was approved to use the "special sign for geographical indication products." The Codonopsis pilosula industry is one of the pillar in...

AI Technical Summary

Problems solved by technology

The Codonopsis ginseng industry is one of the pillar industries in Wenxian County. However, the existing Codonopsis ginseng seedling cultivation technology is backward. The operation method is to select the raw wasteland in the high-altitude shady slope and humid zone above 2,500 meters above sea level, cut off the vegetation, and plow it deeply. Soil, rake out weed roots, spread seedlings, do not cover with any material

The defects of this traditional method of raising seedlings are: 1. The requirements for soil moisture are high, and the seedling emergence rate is very low in places with lower altitudes, which limits the areas that can be selected for seedling raising. The transportation of materials is very inconvenient and the labor efficiency is low. Second, there is no need to raise seedlings in mature land, and the wasteland will be reclaimed and destroy vegetation, resulting in soil erosion. Third, without coverage, the soil surface is dry and wet alternately, the emergence rate is very low, and a lot of seeds are wasted.

[0003] In summary, the production cost of traditional plain-flowered Codonopsis is high, the economic benefits are low, and it is difficult to raise seedlings. The production scale of Codonopsis pilosula is constantly shrinking, resulting in a tight supply of medicine sources.
