Artificial licorice root planting technique

Abstract

The invention discloses an artificial licorice root planting technique and belongs to the technical field of licorice root planting. The technique is characterized by comprising the following steps: selecting a sandy soil land which has a low underground water level, a deep, thick, loosened and fertile soil layer and good water drainage; selecting annual seedlings of which the residual stem partsare 8mm or greater and the tap root lengths are not less than 50cm; drilling planting holes of 120-140cm vertically downwards on the sandy soil land, vertically inserting the residual stem part of oneseedling into one planting hole, burying the residual stem part for 5-20cm deep, flashing sandy soil into gaps of the planting holes with water to fully fill and compact the holes; weeding and loosening soil in a first year; covering with soil for 20cm in a second year. The planting technique has the purposes that root systems do not extend and grow downwards, the drought resistance can be improved, and the survival rate can be increased; in the growth process, watering, sterilization or pesticide spraying are avoided, and a rapid growth speed is achieved; the yield is 2-3 times of that of aflat planting method; at a wild state, the yield per mu of plants of three years can be up to 1-1.2 tons, and the yield of five years is up to 3-3.5 tons.

Description

technical field [0001] The invention belongs to the technical field of licorice cultivation, in particular to an artificial licorice cultivation technology. Background technique [0002] Licorice is a perennial herb of leguminous family, and its roots and rhizomes are used as medicine. Sweet in taste and flat in nature. Licorice is the king of traditional Chinese medicine, and it is listed as the first of all medicines in "Compendium of Materia Medica". effect. Licorice acid drugs have the effects of preventing and treating viral hepatitis, hyperlipidemia, anti-cancer, anti-cancer and regulating the immune function of human cells. The aerial part of licorice has high crude protein and crude fat content, and low crude fiber content. The stems and leaves contain various trace elements needed by animals. The feeding effect is similar to that of alfalfa, and the output remuneration is slightly higher than that of alfalfa. It can be used as An excellent legume forage. In rec...

Problems solved by technology

However, there are many defects in the flat load method: the root system of the transplanted seedlings is mainly distributed in the shallower soil layer, and the drought tolerance is relatively poor; it is necessary to carry out the topdressing operation after the seedlings are settled and the licorice seedlings grow to about 20cm; The grown licorice seedlings are not strong enough and are vulnerable to pests and diseases, so pest control work is required
