A solar greenhouse seedling raising method capable of increasing the germination rate of angelica

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 method for raising seedlings of angelica that can increase the germination rate, reduce the disease rate, and reduce the bolting rate, belonging to the technical field of Chinese herbal medicine planting, and specifically relates to a method for raising seedlings in a sunlight greenhouse that can increase the germination rate of angelica. Background technique [0002] Angelica is a perennial herb, the whole plant has a special aroma. The main root is thick black, large and fleshy, and the lower part contains many thick and long branched roots; the stem is upright and purple; the compound umbel is terminal and double-hanging fruit. Its dry storage root is one of the commonly used Chinese medicinal materials. It has a long history of medicinal use. There are records in all dynasties of Materia Medica. It was first recorded in the "Shen Nong Materia Medica" that "Angelica sinensis is warm in taste, and the main hiccup is...

Problems solved by technology

However, the long-term treatment of the soil layer with pesticides will not only kill the beneficial microorganisms in the soil, but also lead to an imbalance in the distribution of the biological communities in the soil layer. If things go on like this, the soil fertility will decrease significantly; and, after repeated rains or watering, the drugs distributed in the soil layer If it is continuously diluted, it loses its efficacy and cannot achieve obvious effects. It needs to be mixed with medicine continuously, which not only takes time and effort, increases costs, but also causes the sand content of the soil to increase continuously, destroying the original ecological balance.

[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
