Method for improving productivity and quality of liquorice seeds

Abstract

The invention belongs to the technical field of plant breeding and elite breeding and relates to a production method of liquorice elite breeding. The production method includes the following steps that firstly, a growth period is met and fruit abortion is relieved; secondly, the planting density is limited and seed yield is ensured; thirdly, fertilizing management is performed and bud breeding and blossoming are ensured; fourthly, drought and flooding are prevented and the number of blooming flowers is reduced; fifthly, artificial supplementary pollination is performed; sixthly, the coordinating relation between nutrition growth and reproduction growth is regulated, the density of flowers and fruits is low and the maturity degree is improved; seventhly, insects are prevented and treated and the quality of seeds is improved; eighthly, overwintering and coldness preventing are performed and freeze injuries to flower buds are reduced; ninthly, blended selection and seed collecting are performed and the purity of the seeds is ensured. According to the production method of liquorice elite breeding, the liquorice growth environment is improved, fertilizing is performed according to a formula, and planting is performed reasonably and densely, so that the cycle of blooming and podding of seeds is shortened and the seed podding rate, the maturity degree and the yield are correspondingly improved. The technical barrier in artificial cultivation of liquorice seeds in production is effectively removed, the yield and the quality of the seeds are improved, the situation that wild seeds are gradually less is relieved and the demand for seeds in the market is met.

Description

technical field [0001] The invention belongs to the technical field of plant breeding and breeding of fine varieties, namely a method for improving the yield and quality of licorice seeds. Background technique [0002] Licorice is a plant of the genus Licorice in the family Leguminosae, mainly Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat. or Glycyrrhiza glabr. Licorice is the most widely used Chinese herbal medicine among more than 6,000 kinds of Chinese herbal medicines in my country, with an annual consumption of more than 60,000 tons. At present, wild licorice has been excavated continuously for 60 years in Northeast, Northwest, and North my country, and nearly 80% of the resources have been destroyed. Taproots with a diameter of more than 1.0 cm are rare, and underground roots and rhizomes are less and less stored. As the main source of licorice seeds is wild licorice, it poses a great threat to the production and supply of licorice seeds. While cultivating wil...

Problems solved by technology

By improving the growth environment of licorice, formula fertilization and reasonable close planting, the seed flowering and pod setting period is shortened, and the seed pod setting rate, maturity and yield are correspondingly improved. Quality, alleviate the situation of fewer and fewer wild seeds, and ensure the market demand for seeds
