Mulching film breeding method of seedlings of traditional Chinese medicinal materials

Abstract

The invention provides a mulching film breeding method of seedlings of traditional Chinese medicinal materials. According to the method, the mulching film is mulched on the ground, holes are formed in the mulching film, and seeds are thrown into the holes and are mulched with thick wet soil and sealed with thick sand; owing to the isolation effect of the mulching film, the soil moisture evaporation speed is relatively decreased, the soil moisture can be stored in the soil for a long time, ground temperature can be increased effectively, and sufficient moisture and proper temperature are provided to the seeds for germinating; when mulching film mulching planting is performed, medicine seedlings aboveground parts have no mulches, incidence of pests and diseases is reduced, pesticide usage is reduced, and germination rate of the traditional Chinese medicinal materials is increased effectively.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a seedling raising method, in particular to a film-mulching seedling raising method of Chinese medicinal materials. Background technique [0002] Seedling cultivation of Chinese medicinal materials is mainly in spring, and drought in spring is the main restrictive factor for seedling cultivation of Chinese medicinal materials. [0003] The traditional method of sowing seedlings is to directly scatter the seeds on the flat surface of the rake, use a plow to cut the surface into shallow furrows, sprinkle the seeds into the shallow furrows, then level them, compact them, and then cover them with thick fine sand or wheat grass to keep moisture. In spring, the soil moisture content is low, the ground temperature is low, and the seeds of Chinese herbal medicines require a lot of water to germinate. During the seedling raising period, open-field seedlings cannot effectively maintain soil ...
