Method for breaking hard seed dormancy in astragalus seeds

Abstract

The invention discloses a method for breaking hard seed dormancy in astragalus seeds, relates to a method for producing the astragalus seeds, and belongs to the field of traditional Chinese medicine planting. The method is characterized by comprising the following steps of: soaking the astragalus seeds into 70 to 75 percent alcohol for 5 to 10 minutes for sterilization, and washing the astragalus seeds by using sterilized water for 2 to 3 times; and after guar gum culture medium is fully grown with microorganisms, spreading the astragalus seeds on the culture medium in a density of 26 to 34 seeds / cm<2> at the temperature of between 25 and 30 DEG C for 24 to 96 hours. The method has the advantages that the astragalus seeds are treated by one of trichoderma harzianum, aspergillus oryzae and aspergillus niger or the mixture of two or all of trichoderma harzianum, aspergillus oryzae and aspergillus niger, the hard seed dormancy in the astragalus seeds can be effectively broken, and the germination rate is improved by 10 to 30 percent; and the trichoderma harzianum, aspergillus oryzae and aspergillus niger or the mixture thereof are or is easily obtained and cultured, and can be used for preparing a coating agent or a seed dressing microbial agent for the astragalus seeds, cost is low, and the method has a quite wide market prospect in the production practice of astragalus seeds.

Description

technical field [0001] The invention relates to a method for producing astragalus seeds, which belongs to the field of planting traditional Chinese medicines, in particular to a method for breaking the hard dormancy of astragalus seeds. Background technique [0002] Astragalus, also known as Astragalus, is a general term for plants and Chinese medicinal materials. The plant Astragalus is produced in Inner Mongolia, Shanxi, Gansu, Heilongjiang and other places, and is a national third-level protected plant. Modern research shows that Astragalus contains saponins, sucrose, polysaccharides, various amino acids, folic acid, selenium, zinc, copper and other trace elements. It can enhance the immune function of the body, protect the liver, diuretic, anti-aging, anti-stress, lower blood pressure and have a wide range of antibacterial effects. In recent years, the output of wild Astragalus membranaceus is very small, and the market needs are supplied by artificial planting. Astra...

Problems solved by technology

[0004] However, using the above methods to break the hard dormancy of hard leguminous seeds, for seeds of different species, varieties, different degrees of maturity and different years of storage, the treatment time (sun exposure), treatment temperature and concentration (hot water soaking, chemical treatment) and treatment Pressure (physical milling) and other differences are very large, and it is not easy to control. At the same time, chemical methods are harmful to the seeds; the treatment effect in production practice is often unsatisfactory; due to the small size of Astragalus seeds, it is currently difficult to break the hard dormancy of Astragalus seeds. no ideal solution yet
