Liquorice planting method

Abstract

The invention relates to a liquorice planting method which comprises the steps of: land preparation, fertilizer application, film covering and seeding, wherein the land preparation comprises the steps of deep loosening, soil breaking and ridge forming, and the seeding adopts an underfilm precise dibble seeding technology replacing with the strip seeding and the seedling raising transplanting in the traditional planting method. The planting method can effectively improve the structure of deep soil at the root of liquorice, promote the upward development of the root of the liquorice, and reduce the growth resistance of the root of the liquorice; and the grown liquorice has the advantages of one stem without branches, less hair quantity and high yield.

Description

technical field

[0001] The invention relates to a method for planting licorice, in particular to a method for planting licorice with subsoiled broken soil and ridges. Background technique

[0002] At present, artificial planting of licorice is distributed in Northwest my country, North China, and Northeast China, which has unique geographical environment and climate conditions such as drought, little rain, strong light, large temperature difference between day and night, cold winter and hot summer. As the demand for licorice in our country continues to grow, it is difficult to meet the development of social needs by manually digging wild resources, and it also causes damage to wild resources. At present, licorice is planted by traditional manual planting or manual transplanting, and mechanical seedling cultivation. It takes three years to harvest, and the yield per mu is 900-950 kg. This planting method has high labor intensity, long growth cycle, large proportion of wool a...
