Problems solved by technology

[0002] Licorice is extremely wild. Under the natural wild growth state, it takes the third year for the licorice to bloom and set seeds, and the seed hardening rate reaches 90%. When the seeds are sown in a natural state, it is quite difficult to emerge, and they need to be buried in the soil for 3- It takes 5 years to germinate, and the emergence rate is less than 15%
If the concentration of sulfuric acid is too high or the treatment time is too long, the burned area of ​​the seeds will be too large and the vigor will be reduced or lost. In addition, during the acid treatment process, the seed coat of some non-hard seeds is damaged, and the sugar in the kernel reacts with sulfuric acid to produce furfural and water, which will lead to imbibition of the treated seeds or fever, leading to a greater decline in vitality
[0003] Because licorice seeds are expensive, the grains are small, and the rate of firmness is high, hard seeds and non-hard seeds exist at the same time in the seed batch, which leads to the problem of decreased seed vigor or incomplete treatment during acid treatment.

Abstract

The invention relates to a method for processing seeds before seeding, and in particular relates to a method for breaking the hardness of licorice seeds by using foamed acid. The invention aims at providing a method for breaking the hardness of licorice seeds by using foamed acid which can be used for quickly, safely and efficiently breaking hardness of licorice seeds, reducing burn area, preventing an 'imbibition' phenomenon in the seed processing process, and keeping the vitality of seeds, and can be operated on a large scale. The method for breaking the hardness of licorice seeds by using foamed acid provided by the invention mainly comprises the following steps: preparing the foamed acid; mixing the foamed acid and the seeds; and cleaning and drying in shade of the seeds. According to the method for breaking the hardness of licorice seeds provided by the invention, the operation is safe, and sulfuric acid and labor are saved; the licorice seeds produced by the method provided by the invention are small in burn area, high in vitality index and germination index, high in rate of emergence, and beneficial to seed priming, coating and pelleting. The method provided by the invention is used in the fields of production and processing of the licorice seeds, and licorice artificial cultivation.

Description

technical field [0001] The invention relates to a method for treating seeds before sowing, in particular to a method for treating hard seeds before sowing. Background technique [0002] Licorice is extremely wild. Under the natural wild growth state, it takes the third year for the licorice to bloom and set seeds, and the seed hardening rate reaches 90%. When the seeds are sown in a natural state, it is quite difficult to emerge, and they need to be buried in the soil for 3- It takes 5 years to germinate, and the emergence rate is less than 15%. Therefore, wanting to develop artificial cultivation of licorice, researching licorice seed treatment technology is the first major difficulty. Licorice seeds have a hard seed coat, which is a form of dormancy. The method of artificially softening the seed coat has been widely used to reduce the hardness of the seed coat and improve the germination rate, emergence rate and consistency of seeds. It has now been proven that hot wate...
