Seedling breeding method of dangshen mulching film suitably used in arid mountainous area

Abstract

The invention discloses a seedling breeding method of a dangshen mulching film suitably used an arid mountainous area. The seedling breeding method comprises following steps of: preparing soil, applying fertilizers and using pesticides; finishing seedbeds; uniformly sowing; covering with a plastic film; performing field management; and lifting seedlings and harvesting. The seedling breeding method of the dangshen mulching film suitably used in the arid mountainous area has following beneficial effects: by integrating anti-drought measures such as temperature increase and soil moisture conservation, moisture perseveration and increase, rain collection, seepage storage and runoff interception with pest control, single fertilization is adopted for control over underground insects and soil-borne diseases; the manner of firstly finishing seedbeds, sowing and then covering with the plastic film is adopted and the plastic film mulching is utilized for replacing straw mulching of conventional crops so that the problem that film-mulching cultivation technique can be not applied to seedlings growing of dangshen in the arid mountainous area is solved; per unit yield of seedlings growing of dangshen in the arid mountainous area is significantly increased; the seedling breeding method of the dangshen mulching film suitable in the arid mountainous area is especially suitable for seedlings growing in dry land of arid and semiarid rain fed agricultural regions; the seedling breeding method is anti-drought, low in cost and investment, high in output, easy in application, convenient in promotion and popularization and capable of preserving complete seedlings and cultivating robust seedlings and is easy and practicable and helps to save labor; and a great application prospect and economic benefits are obtained.

Description

technical field [0001] The invention relates to a method for raising seedlings of medicinal crops, in particular to a method for raising seedlings of Codonopsis pilosula with plastic film suitable for 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. The traditional method of raising seedlings by medicine farmers is fertilization, pesticide application, plowing, raking to level the land, sowing seeds, shallow plowing of seedbeds, raking and suppression, and covering crop straw. The amount of straw is large, 300-350kg of crop straw is needed per 667 square meters, and the thickness of the artificial covering is uneven, resulting in uneven emergence. The st...

The traditional method of raising seedlings by medicine farmers is fertilization, pesticide application, plowing, raking to level the land, sowing seeds, shallow plowing of seedbeds, raking and suppression, and covering crop straw. The amount of straw is large, 300-350kg of crop straw is needed per 667 square meters, and the thickness of the artificial covering is uneven, resulting in uneven emergence. The straw also contains a large number of pathogenic bacteria and certain weed seeds, which increases the workload and labor intensity of field management. Large investment, little effect of increasing temperature and moisture and preserving seedlings
