Method of harvesting white atractylodes rhizome seeds

Abstract

The invention discloses a method of harvesting white atractylodes rhizome seeds. According to the method, the clarity of the harvested atractylodes rhizome seeds can reach up to above 96% and the hundred-grain weight can reach up to above 2.1532g by determining the best seed harvesting period, harvesting, drying, kneading, removing fuzzes, winnowing, bagging and storing. Compared with the 1.7749g of the hundred-grain weight, the seed quality index can be significantly improved, the empty rate can be reduced, the problems that the seeds are bad in quality and are free from endurable storage can be caused by green and empty seeds due to premature in the prior art can be effectively solved, the harvesting quality of the atractylodes rhizome seeds can be improved, the quality guarantee can be provided for the planting, sowing and seedling raising of the atractylodes rhizome seeds, the waste of atractylodes rhizome seeds can be prevented, the seed quality and seed clarity can be improved by adopting a way of drying and then kneading, and the storage time and germination rate of the seeds can be improved by adding peppers and controlling the storage temperature in a refrigeration house; furthermore, the method has the characteristics of being simple in harvesting method and high in harvesting efficiency.

Description

technical field [0001] The invention relates to a technique for harvesting Atractylodes macrocephala seeds, a traditional Chinese medicinal material, in particular to a method for harvesting Atractylodes rhizome seeds of Compositae. Background technique [0002] Atractylodes Atractylodes macrocephala Koidz. is Asteraceae Echinochloa crus-galli (L.), Atractylodes Atractylodes Perennial herb, its rhizome is used as medicine; its taste is bitter, sweet, and warm in nature; it belongs to the spleen and stomach meridians, and has the effects of invigorating the spleen and replenishing qi, drying dampness and diuresis, antiperspirant, and antifertility; Atractylodes macrocephala is a flower head, generally with 6 -10 involucre, bract leaves green, 3-4 cm long, needle-like pinnately divided, involucre large, broadly campanulate, 3-4 cm in diameter, apex purple-red; all bracts have blunt apex, margins White spider silk hairs; achenes obconic, 7.5 mm long, covered with dense wh...

Problems solved by technology

[0003] At present, there are few reports on the harvesting technology of Atractylodes macrocephala seeds. The harvesting in production mainly depends on the traditional experience of farmers, but the method is not scientific and rational; Harvested seeds are immature, high in water content, perishable and degenerate, not resistant to storage, less accumulated nutrients, more shriveled seeds, less plump seeds, low germination rate and germination potential, and weak seedlings after germination; harvested too late, After the seeds mature, they will germinate in the involucre by themselves, consume nutrients, and the quality of the seeds will seriously decline. They usually fall off about half a month after maturity, and cannot be collected after falling off.

Harvesting must be carried out when the seeds are fully mature, and it must be harvested in time to prevent the seeds from maturing and falling off. After harvesting, measures such as drying, hair removal, and deflated seeds are required. Therefore, this is a complicated technical work.

At present, the harvesting method of Atractylodes macrocephala seeds is relatively primitive. Due to the lack of scientific and reasonable technical means in the harvesting period, harvesting method, harvesting, preparation and other processes, the seeds are shriveled, there are many sundries, the purity is low, and the seeds are not properly stored to germinate. rate drop, seed moldy, intolerance to storage, etc. Under natural indoor temperature and humidity conditions, it can be stored for up to half a year. Within one year of indoor natural temperature and humidity storage, the germination rate of its seeds is almost zero, losing its seed value.
