High-yield liquorice planting method

Abstract

The invention discloses a high-yield liquorice planting method, which includes: firstly, preparing soil; secondly, mechanically spreading films for seeding; thirdly, performing drip irrigation under the films and applying soluble fertilizer; fourthly, mechanically harvesting; and the like. Planting by the method can be performed in temperate zones and north temperate zones with continental climate. By the method, large-area and normalized liquorice planting can be realized. Work efficiency of planting by the method is 50-60 times of that of manual planting, indexes of planted liquorice meet requirements of GAP (good agricultural practice for Chinese crude drug), and the high-yield liquorice planting method is low in investment and high in benefit. The high-yield liquorice planting method frees liquorice farmers from heavy labor, realizes large-scale mechanical operational area, and enables the industry of liquorice to be rapidly developed in arid and semiarid areas, so that great social and economic benefits can be created and good ecologic benefits can be brought.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a high-yield planting method of licorice. Background technique [0002] Licorice is also known as sweet grass, sweet roots, sweet licorice, etc., and its roots and rhizomes are used as medicine. Contains glycyrrhizic acid, glycyrrhetinic acid, glycyrrhizin, flavonoids and coumarins. Sweet in taste and flat in nature, it is an important bulk of traditional Chinese medicinal materials. It has the functions of nourishing the spleen and replenishing qi, clearing away heat and detoxification, eliminating phlegm and relieving cough, relieving spasms and relieving pain, and reconciling various medicines. Licorice is widely used in traditional Chinese medicine. The national traditional Chinese medicine management department will Licorice is listed as one of the four major medicinal materials under key management. At the same time, licorice is not only an important food and cosmet...

Problems solved by technology

[0005] In the prior art, most of the artificial planting of licorice adopts the planting method of raising seedlings first and then transplanting, which is not easy to adopt mechanized large-scale planting, and the root system of licorice is relatively long. In the ditch, the licorice root seedlings overlap in the soil in this planting method, which is not conducive to fully absorbing and utilizing the nutrients and water in the soil. The yield of licorice is low. In order to compete for and fully absorb the nutrients and water in the soil, many roots grow downward Growing fine roots; if the irrigation amount and irrigation time are not well controlled, it will also cause the main root to extend too long or have too many hairy roots, and the quality of licorice is poor.
