Method for cultivation of seedlings of bulbus fritillariae cirrhosae through devices

Abstract

The invention relates to a method for cultivation of seedlings of bulbus fritillariae cirrhosae through devices. The method comprises the step of the site selection process, the step of greenhouse building key point process, the step of the seed after-ripening processing process, the seedling management process and the like. The method is characterized in that greenhouse cultivation is carried out on the seedlings of the bulbus fritillariae cirrhosae with the age ranging from one year to three years, the optimum temperature, the optimum humidity, the optimum overshadowing degree and the best fertilizer and water conditions required by growth of the seedlings are provided for the seedlings, and the rate of emergence of seeds and the bulblet seedling survival rate of the seeds namely the overyear bulblet survival rate are increased, so that a large number of seedlings of the bulbus fritillariae cirrhosae are produced, and the foundation is laid for achieving artificial cultivation industrialization of bulbus fritillariae cirrhosae commodity medicinal materials.

Description

technical field [0001] The invention belongs to the technical field of cultivation of Chinese medicinal materials, and in particular relates to a facility seedling cultivation method of fritillary fritillaria. Background technique [0002] Fritillaria sichuanensis is an important medicinal material resource, and the preparations of Fritillaria sichuanensis recorded in the "Chinese Pharmacopoeia" (2005 edition) accounted for 3.01% of the total preparations, but the medicinal materials of Fritillaria sichuanensis still rely on wild resources since ancient times. The natural conditions of the original place of Fritillaria fritillata are harsh, the growth cycle is long, the reproduction rate in the wild is extremely low, and the resource renewal is extremely slow. Domestic experts have just started its artificial cultivation research since the 1980s, but the raw material supply of medicinal materials has not been solved. The reason is that the cultivation and growth cycle of Fr...

AI Technical Summary

Problems solved by technology

Domestic experts have started their artificial cultivation research since the 1980s, but the supply of raw materials for medicinal materials has not been resolved.

The reason is that the cultivation and growth cycle of Fritillaria fringiosa is about 5 to 6 years (the longest field condition may be as long as nearly 10 years). The emergence rate and seedling retention rate of open field cultivation are extremely low, it is difficult for seedlings to compete with weeds, and the ability to resist drought is extremely weak

[0003] Therefore, the production cost of the traditional cultivation method is extremely high and it is difficult to form an industrialized commercial medicinal material supply. The use of facilities for seedling cultivation and artificial condition intervention at the 1-3 year seedling age of Fritillaria fritillaria can greatly improve the seed emergence rate and seedling preservation rate (ie The survival rate of small bulbs every other year), supply a large number of high-quality fritillaria seedlings
