A Method of Seedling Breeding of Fritillaria

Abstract

The invention relates to a method for seedling raising of Fritillaria, which comprises the following steps: (1) the humus-containing loam soil or sand is selected as the nursery land of Chlamydomonas subspecies; (2) the land of the control tiger are strewed by Pesticide 1- 2kg; (3) 15- 20 days later, the land is made to the ridge, the base fertilizer are spread on the ridge, and then soil, cover the base fertilizer, level the land, and finally cover with 1cm- 1.5cm mountain (5) to keep the soil moist, until spring emergence, cover density of 50 after emergence- 60 sun-shade net.(4) the pretreatment of seeds are sprinkled on the ridge, the seeds are covered with shrimp, pine and cooked soil; 60 shade net; (6) Miao long 3cm after every 20-25 days fertilizer once, fertilizer in accordance with the 300kg per mu, according to the amount of 5kg per acre, 45-60 days spraying foliar fertilizer once. The seedling rate of the seedling is less than 4%, and the rate of insects is less than 1.5%, and the germination rate is 90.2%.The incidence rate is less than 3.5%, the seedling rate is 93.4% , bulb weight to 1.5g, much higher than the existing nursery method.

Description

technical field [0001] The invention relates to a seedling raising method of Fritillaria sichuanensis, which belongs to the field of planting Chinese herbal medicines. Background technique [0002] Chuan Fritillaria is a good medicine for relieving cough and reducing phlegm, and it is widely prescribed in traditional Chinese medicine. There are more than 200 kinds of Chinese patent medicines produced with Fritillaria sichuanensis as raw materials. The current annual output of Fritillaria sichuanensis is only 27 to 50 tons, while the market demand should be more than 1,500 tons. At present, the wild resources of Fritillaria sichuanensis are seriously depleted (already listed Class III in the catalog of plant medicinal materials under national key protection), the price remains high (and has an upward trend), the circulation and use of commodities are chaotic (shoddy, other kinds of fritillary fritillary instead of fritillary fritillaria), seriously affecting the preparation ...

Problems solved by technology

[0005] The invention provides a method for raising seedlings of Fritillaria sichuanensis, which solves the problems that the existing seedling raising methods lack the factors that generally consider the raising of Fritillaria sichuanensis seedlings, which makes the seedlings thin and weak, the survival rate is low, and the time for raising seedlings is unbalanced.
