Abstract

The invention relates to the technical field of planting traditional Chinese medicinal materials, specifically discloses a pre-treatment agent for Chinese medicinal materials and its application, and also discloses a method for pre-treatment of Polygonum villosa buds by using the pre-treatment agent. The pre-seeding pretreatment method of the present invention can play a good inhibitory effect on various pathogenic microorganisms existing in the bulbils by soaking the Polygonum bulbils in the soaking liquid and combining light treatment during the soaking process, and then carry out the germination treatment, Spray chitosan aqueous solution to the bulbils in the germination process, and the bulbils obtained after treatment can be sown. Through the synergistic effect of the active ingredients ε‑polylysine, nisin or natamycin and chitosan in the soaking liquid, it can promote the secondary germination and leaf formation of bulbils, significantly improve the germination and rooting speed of field planting, and significantly Improve germination.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a seed pretreatment agent for traditional Chinese medicinal materials and its application, and also relates to a method for pretreating Polygonum viburnum buds by using the pretreatment agent. Background technique [0002] Polygonum viburnum is a plant of the genus Polygonum in the family Polygonaceae, a perennial herb. The flowering period is from May to July each year, and the fruiting period is from July to September. Wild Polygonum viburnum mainly grows in the alpine meadow area at an altitude of 2500-5000m. The plateau's unique topographical structure, complex geographical conditions and diverse climate characteristics make it a concentrated distribution area of ​​Polygonum viburnum. At present, with the wild excavation of Polygonum viburnum, its wild resources have been seriously scarce, and wild excavation has also caused great damage to the p...
