Cultivation method for improving maturing rate and yield of liquorice seeds

Abstract

The invention relates to a cultivation method of liquorice, in particular to a cultivation method for improving the maturing rate and the yield of liquorice seeds. The method includes the following steps that main roots of the liquorice are selected; sandy soil is selected; farmyard manure is applied to be ploughed deeply and raked to be fine and flat; processing of improving the root stock survival rate is performed on the main roots; the main roots are reasonably and densely planted in spring or winter; watering is performed at least four times each year, and watering is performed in the range of 60-100 cubic meters each time per mu; fertilizer applying is performed two times each year; solutions for restraining the vegetative growth of the liquorice and promoting the reproductive growth are sprayed in the first ten days of June each year; the tops of liquorice plants are cut off in the late ten days of July each year; broad-spectrum pesticides are sprayed in the middle ten days of May and the middle ten days of July to prevent insect damage; the liquorice seeds are harvested in the middle ten days of August each year from the second year since planting. With the method, pest and disease damage such as liquorice pulse beetles can be effectively avoided, harvesting is reasonable, premature harvesting is prevented, and the quality of the liquorice seeds is improved.

Description

technical field [0001] The invention belongs to the technical field of plant planting and cultivation, and in particular relates to a cultivation method of licorice, and more particularly to a cultivation method for increasing seed setting rate and yield of licorice. Background technique [0002] Licorice is the dried root and rhizome of Glycyrrhiza uralensis Fisch., Glycyrrhiza inflate Bat., or Glycyrrhiza glabra l., a leguminous plant, and is a commonly used bulk medicinal material in my country. It has the effects of nourishing Qi, clearing heat and detoxification, eliminating phlegm and relieving cough, relieving spasm and relieving pain, and reconciling various medicines.
