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

The licorice planting method

Technical field

The present invention relates to a kind of licorice planting method, refer in particular to a kind of native ridging licorice planting method that ravels deeply.

Background technology

At present the Radix Glycyrrhizae artificial planting is distributed in NORTHWEST CHINA, North China and the Northeast, its have arid, short of rain, illumination is strong, day and night temperature is big, unique geographical environment weather conditions such as winter cold, sweltering heat in summer.Along with China's Radix Glycyrrhizae demand constantly increases,, also cause destruction to wild resource by the mode of manually the excavating wild resource development that is difficult to satisfy social needs.The plantation Radix Glycyrrhizae is adopted traditional artificial planting or artificial the transplanting at present, and machinery is grown seedlings, and needs gather in 3 years, and per mu yield is at the 900-950 kilogram.This kind method for planting labour intensity is big, and growth cycle is long, and the careless ratio of hair is big, and at the bottom of the yield rate, collar is not long, and lateral root side neck is many, and the collar diameter uniformity is poor, and benefit is low.

Summary of the invention

The purpose of this invention is to provide the dark loose ridging licorice planting method of a kind of mechanical hack, grow seedlings to overcome traditional artificial planting or machinery, the problem of long, the poor product quality of growth cycle in the transplantation technique.

The present invention solves the problems of the technologies described above and the technical scheme that provides is:

Licorice planting method, its step comprise whole ground, fertilising, overlay film, sowing, described dark pine, hack and the Cheng Long of comprising wholely, and precision point sowing technology under the film is adopted in described sowing, replaces drilling and seedling raising and transplanting in existing kind of the method for planting.

Further be improved to, during whole ground, dark loose 0.5-1.5 rice, dark loose furrow width 18-60 centimetre, natural ridging on the ditch; During overlay film, machinery shop film, and lay the irrigate band.

Moreover during fertilising, alternative tradition is spread fertilizer over the fields fertile method, carries out the concentrated fertilising of machinery on the ridge, and fertile amount is: compoiste fertilizer 10-30 kilogram/mu, pure potash fertilizer 10-20 kilogram/mu, diamines 10-15 kilogram/mu, fertilization depth 10-15 centimetre.

Moreover during sowing, the Radix Glycyrrhizae seed stirs through bright sulfur acid and soaked 15-20 minute, and soaking temperature is 10-35 ℃, and rinse the Radix Glycyrrhizae seed well with clear water the back, removes residual acid and dry.Conventional Radix Glycyrrhizae seed treatment all adopts artificial or mechanical breaking-wall method technology, influences percentage of seedgermination.

Moreover, during precision point sowing, adopt a ridge duplicate rows program request or a ridge four lines program request technology, sowing depth 1.5-2.0 centimetre, plant the slight earthing 1.0-1.5 in cave centimetre.Wide every trade is apart from 88-102cm, narrow row line-spacing 10cm, spacing in the rows 10cm.13072-15152 cave/mu is counted in theoretical mu cave.11100-12800 strain/more than the mu is counted in the strain of keeping a full stand of seedings.

This kind of method for planting can effectively improve Radix Glycyrrhizae root deep soil structure, promotes the Radix Glycyrrhizae collar to develop downwards, has reduced Radix Glycyrrhizae collar growth resistant, has controlled the horizontal development space of lateral root side neck, creates the condition that good Radix Glycyrrhizae collar is independently grown.The only neck of Radix Glycyrrhizae that grows under this soil environment condition does not have wooden fork, and hair grass amount is few, the yield rate height, thus improved the Radix Glycyrrhizae yield and quality, shorten growth cycle and reduced the production cost of knowing clearly.

Embodiment

Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
