A film-covering cultivation method suitable for planting Codonopsis pilosula in arid mountainous areas

Abstract

The invention discloses a plastic-film mulching cultivation method for dangshen plantation suitably used in an arid mountainous area. The plastic-film mulching cultivation method comprises following steps: preparing soil and applying fertilizers; processing seedlings; digging trenches and cultivating; performing fine management and harvesting. The plastic-film mulching cultivation method for dangshen plantation suitably used in the arid mountainous area has following beneficial effects: advanced plastic-film mulching cultivation technology is utilized for replacing conventional dangshen plantation and anti-drought measures such as temperature increase and soil moisture conservation, moisture perseveration and increase, rain collection, seepage storage and runoff interception are integrated with weed control, control of pests and diseases and automatic seedling technology, light rainwater turns into heavy rainwater and uneffective precipitation turns into effective precipitation by utilization of an arch film surface for rainwater collection; soil seepage storage between ridges. precipitation collected by the film surface and soil evaporation collected inside the film are utilized for directly supplying moisture into dangshen seedlings; passive drought resistance becomes active drought resistance; microbial insecticides are utilized for controlling underground pests and soluble microbial products; botanical bactericides are utilized for controlling soil-borne diseases; the manner of firstly planting seedlings, ridging and then laminating is adopted so that heads of dangshen seedlings are kept outside a mulching film; other parts are kept into the mulching film; and the working link of releasing seedlings is eliminated.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a film-covered cultivation method suitable for the cultivation of Codonopsis pilosula in arid mountainous areas. Background technique [0002] At present, the production, development and utilization of Chinese herbal medicines have received great attention and strong support from the state, province and city, and they have been upgraded to a pillar industry with agricultural characteristics and become the main source of income for farmers in mountainous areas. Yaonong’s traditional Codonopsis cultivation method is to first fertilize, apply pesticides, plow, level the land, open planting ditches, spread seedlings, bury seedlings, and suppress. Not only is the field operation extensive, but also under the condition of continuous spring droughts, in order to ensure the basic number of seedlings per unit area, only high-density cultivation is required, which not ...

Problems solved by technology

Not only is the field operation extensive, but also under the condition of continuous spring droughts, in order to ensure the basic number of seedlings per unit area, only high-density cultivation is required, which not only increases the unit cost, but also increases the workload and labor intensity of field management, resulting in low and unstable yields. The application of a large number of chemical insecticides and fungicides violates the basic requirements for the production of traditional Chinese medicinal materials. The problem of excessive pesticide residues in products is very prominent, and the agricultural ecological environment is also seriously polluted.

[0003] Plastic film mulching technology is widely used in various crops as a basic technology of "advanced, applicable, simple and efficient" in my country, but it is still blank in the cultivation of Codonopsis pilosula
