Astragalus membranaceus seed mechanical skin-breaking treatment method adopting preliminary classification

Abstract

The invention discloses an astragalus membranaceus seed mechanical skin-breaking treatment method adopting preliminary classification. The treatment method firstly performs sorting and then performs allocating and grinding and includes the following steps: 1) using a seed-cleaning machine to perform sorting on to-be-skin-broken astragalus membranaceus seeds according to sizes, wherein the seeds whose diameters are more than 0.35 cm are grade I seeds, the seeds whose diameters are 0.2-0.35 cm are grade II seeds and the seeds whose diameters are below 0.2 are grade III seeds; and 2) using a ricemill to perform allocating and grinding on the graded astragalus membranaceus seeds, and determining the flow of astragalus membranaceus seeds into the rice mill according to different grading, wherein the flow of the grade I seeds are 23 m<3> / h, the flow of the grade II seeds are 20 m<3> / h and the flow of the grade III seeds are 17 m<3> / h. The treatment method can conveniently determine the processing parameters of grinding technologies, and is more normative in operation and convenient for promotion; the graded seeds are conveniently in grinding, and grinding quality can be enhanced; and therefore, germination rate can be increased, loss can be reduced, the quality of sales and planting can be refined, and the preliminary division of sales and finished product grades can be achieved.

Description

technical field [0001] The invention relates to a seed treatment method in the planting process of Chinese medicinal materials, in particular to a mechanically broken skin treatment method of astragalus seeds. Background technique [0002] The seed coat of a plant is the covering part outside the seed, which has the function of protecting the seed from external mechanical damage and preventing the invasion of diseases and insect pests. At the same time, it is one of the main reasons for seed dormancy. The seed coat of some seeds is thick and solid, which makes it difficult for oxygen to pass through; in addition, there may be germination inhibitors on the seed coat to cause seed dormancy. [0003] The germination rate of Astragalus seeds determines the number of harvested seedlings, but Astragalus seeds are hard seeds, the seed coat is relatively hard, and the hard rate is generally 40%-80%. Due to the dense cell layer and pectin substances outside the seed coat, and The be...
