Cultivation method of facility burdock

Abstract

The invention discloses a cultivation method of facility burdock. The cultivation method of the facility burdock is characterized in that seeds are sown in the middle of August, chlormequat chloride is sprayed to seedlings in the last ten-day period of October to control growth of new leaves, the burdock is transplanted in a plastic greenhouse in the last ten-day period of November, the air temperature and the ground temperature in the greenhouse are increased, the growth time of the burdock is prolonged, the leaves of the burdock are protected in the winter, a leaf fertilizer is sprayed to the burdock in the first ten-day period of December, the burdock can still slowly grow in the winter, the diameter of fleshy roots of the burdock can be 2.5 centimeters or above in February to March of a next year, the length of the burdock can be 70 centimeters or above, the burdock is golden yellow, and the yield of the burdock in per mu is 1,200 kilograms to 1,500 kilograms.

Description

[0001] Technical field: the present invention is the cultivation method of burdock, particularly the cultivation method of facility burdock. Background technique [0002] Burdock is a plant of Compositae, rich in nutrients. It has been a health-care food with the same source of medicine and food since ancient times. It is eaten with fleshy roots and contains inulin, polysaccharides, saponins, flavonoid glycosides, dietary fiber, and polyphenols such as caffeic acid. , chlorogenic acid, isochlorogenic acid and some aldehydes, etc., are important foreign exchange earning vegetables for export in my country. There are two main production methods of burdock in my country, spring sowing and autumn sowing. The harvest period is distributed from late June to early December, and there is no fresh burdock supply for up to 6 months from mid-to-late December to early-to-mid June of the following year. Although storage and preservation technology can prolong the time of burdock on the ma...

AI Technical Summary

Problems solved by technology

Although storage and preservation technology can prolong the time of burdock on the market, the respiratory and metabolic activities in the storage process will consume a lot of nutrients and water, resulting in burdock bran heart and saccharification, seriously reducing product quality and affecting the processing and production of burdock. The supply period of burdock has become a key issue for the further development of burdock industry

Adopt facility cultivation technology to prolong the supply time of fresh burdock. At present, there is no research result of systematic application. On May 24, 2013, the applicant disclosed a cultivation method of summer-sowed burdock. Application number 2013101975930 solved the problem of emergence of summer-sowed burdock Difficult, easy to die and other problems, but the harvest time is also before the end of November. This plan combines the existing cultivation technology, sowing in mid-August, and inserting the arched plastic greenhouse in November to increase the temperature inside the greenhouse and the ground temperature. Prolong the growth time of burdock, so that the leaves of burdock in winter are protected, so that burdock can also grow slowly in winter
