AI Technical Summary

Problems solved by technology

The diameter of the seeds of Gentiana is about 1 mm, and the germination rate of the seeds is extremely low. Under wild conditions, the natural reproduction rate of Gentiana is very low, the growth is slow, and it is difficult to restore the source of medicine
However, there is no ideal technology for artificially cultivating Gentiana chinensis

Embodiment 1

[0042] 1. Seedling cultivation in greenhouse

[0043] 1.1 Seed treatment

[0044] ①Seed harvesting: Harvest seeds and choose wild plants over 3 years old (the second year after transplanting). On September 10, most of the capsules turn yellow and the seeds in them turn brown or brown. Put it into a container that does not leak seeds, transport it back, put it in a ventilated and cool place, and ripen it for 7-8 days. From 10:00 a.m. to 2:00 p.m. on September 18, dry it in the sun and then thresh it. Shake out the seeds again.

[0045] ②Seed storage: After the seeds of Gentiana chinensis are harvested, when the water content of the seeds is about 12-13%, they are stored in cotton bags, which cannot be sealed. During storage, smoke, rodents, insects, and water should be avoided;

[0046] ③The temperature change treatment of seeds: from harvest to November 30th: storage temperature is 20 to 10°C; December: storage temperature is 5 to -3°C; January: storage temperature is 0 to -...

Abstract

The present invention discloses the greenhouse seedling raising and plastic mulching cultivation technology of largeleaf gentian as one kind of rare Chinese medicinal materials. The cultivation process includes the raising seedling comprising seed treatment, soil treatment, seeding, micro sprinkling irrigation, seedling bed management, hardening off and lifting seedling; the transplanting comprising land preparation, applying fertilizer, covering with mulching, sorting seedling and transplanting; and field management comprising intertillage, weeding, winter management, top dressing, irrigation, controlling diseases and pests and harvest. The cultivation process features seed treatment in altering temperature or with gibberellin, seedling bed soil treatment with fertilizer and pesticide, stoving greenhouse at 55 deg.c for 4 hr before seeding, transplanting in 5-6 months after seeding, harvesting in 2-3 years, etc.

Description

technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, in particular to a key technology for artificial cultivation of precious Chinese medicinal material Gentiana chinensis in a greenhouse and a film-covered cultivation method. Background technique [0002] Gentiana chinensis is a commonly used traditional Chinese medicine, flat in nature, pungent and bitter in taste. It has the functions of dispelling rheumatism, clearing damp-heat, and relieving numbness and pain. It is used for rheumatic arthralgia, tendon spasm, joint pain, malnutrition, fever, jaundice, blood in the stool, dysuria, aphtha, bone evaporative fever, hot flashes and polydipsia, and fetal fever in women. The chemical components of Gentianidine traditional Chinese medicine mainly include gentianine (ie Gentianine A, Gentianine), gentianine (ie Gentianidine B, Gentianidine) and Gentianidine C; it also contains volatile oil and sugars. [0003] Gentiana chin...
