Sunlight greenhouse seedling-raising method for improving Chinese angelica germination rate

Abstract

The invention discloses a sunlight greenhouse seedling-raising method with which a Chinese angelica germination rate can be improved. The method comprises the steps of: (1) seed treatment; (2) seedbed preparation; (3) greenhouse controllability improvement; (4) sowing; (5) stem cutting and root insertion; and (6) seedling hardening. The method is characterized in that in the step (1), seeds are scrubbed by using arsenopyrite for removing seed wings, and are sprayed by using sterile water; the seeds are wrapped by using white cotton cloth for 1-2 days for regaining moisture; the seeds are subjected to ultrasonic processing for 30-50min; 0.35-0.40% alpha-sodium naphthylacetate is used for spraying, and the seeds are flatly paved in one layer on a filter paper; the seeds are wrapped by using the filter paper and are buried in composite nutritive soil for germination-promotion for 5-10 days; after germination-promotion, the seeds are sterilized by using 0.1g / L mercuric chloride for 5-6min, and are sterilized by using 0.1g / L sodium hypochlorite for 2-3min. In the step (5) stem cutting and root insertion, when seedlings grow to a height of 3-5cm, 1-1.5cm of aerial stems are cut, and the incisions are sterilized by using 0.1g / L mercuric chloride for 5-6min; the cut stem segments are adopted as female parents, and are transplanted into a germination medium for seedling-raising; and the stem cutting and root insertion seedling-raising step is circulated 2-3 times.

Description

technical field [0001] The invention relates to a controllable angelica seedling raising method capable of increasing the germination rate, reducing the incidence rate, and reducing the bolting rate, belonging to the technical field of planting Chinese herbal medicines, in particular to a solar greenhouse seedling raising method capable of increasing the germination rate of the angelica sinensis. Background technique [0002] Angelica is a perennial herb, and the whole plant has a specific aroma. The main root is thick and black, plump and fleshy, and the lower part is composed of many thick and long branch roots; the stem is erect and purple; the compound umbels are terminal, double-hanging fruits, and its dry storage root is one of the commonly used Chinese medicinal materials, with a long history of medicinal use Herbal medicines have been recorded in the past dynasties. It was first recorded in "Shen Nong's Materia Medica". "The name. In recent years, with the rapid de...

AI Technical Summary

Problems solved by technology

[0004] Finally, the existing angelica seedlings are planted in solar greenhouses for seeds, which realize the controllability of light, temperature, humidity and other conditions on the basis of traditional open air, and have not made breakthrough changes in the key technologies of angelica seedlings. Therefore, its angelica Seedling quality, seedling raising speed and other changes are not obvious, and there are still defects such as slow seedling raising speed and long cycle, and there are also problems such as poor seedling resistance and easy disease
