A breeding method for shortening the fruiting period of licorice seeds

Abstract

The invention discloses a breeding method for shortening the productive phase of licorice root seeds. The breeding method includes the steps of land selection and preparation, breeding material selection and treatment, transplanting, fertilization and management, weeding and water and waterlogging prevention, artificial supplementary pollination, growth control and increase of the set of fruit, pest control, overwintering protection and timely seed collecting. According to the method, a licorice root old root which is more than five years old serves as a breeding female parent, a stolon is cut and transplanted, the productive phase of the licorice root seeds is shortened, and the yield and the quality of the licorice root seeds are improved through the methods that the growth environment of licorice roots is improved, young shoots are pinched off and the like.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, in particular to a breeding method for shortening the fruiting period of licorice seeds. Background technique [0002] Licorice is a perennial herb belonging to the leguminous family. It is one of the most common Chinese medicinal materials. It is known as "ten prescriptions and nine herbs". and, the licorice extract is widely used as an additive in tobacco, cosmetics, food, etc. With the deepening of medical research and the strengthening of development, the market demand for licorice is also increasing year by year, and the market prospect is getting wider and wider. However, traditional licorice mainly collects wild resources, which has caused serious environmental damage. Based on the implementation of the policy of returning farmland to forests, the collection of wild licorice is restricted, and the artificial planting of licorice industry has gradually formed, whi...

Problems solved by technology

[0005] The purpose of the present invention is to: overcome the shortage of existing licorice provenance, long breeding cycle, and high cost, and provide a method for cultivating licorice seeds that shortens the fruiting period of licorice, has low cost, high seed yield and good quality, and can be used for more than five years. The old root of licorice is used as the female parent, and the stolons are cut and transplanted, and the growth environment of licorice is improved, pest management, etc., to achieve the purpose of shortening the fruiting period of licorice
