A method for chemical regulation of milk thistle

Abstract

The invention specifically relates to a chemical adjusting and controlling method of silybum marianum. The silybum marianum at an appropriate growth and development stage is adjusted and controlled by a chemical method, so that the effects of reducing the height of main inflorescences of the silybum marianum, increasing the number of total inflorescences, increasing the number of effective inflorescences, facilitating mechanical harvest, reducing field loss and further effectively increasing fruit yield are achieved. The invention belongs to the technical field of chemical adjustment and control for crops. The specific technical scheme adopted by the invention lies in that the method comprises the following step of at the appropriate growth and the development stage of the silybum marianum, spraying 2-chloroethyl phosphoric acid, 6-benzyladenine, and a compound mixture aqueous solution of a surfactant capable of improving wetting dispersity, adhesion and permeability of pesticides on leaf surfaces. Through the adoption of the method disclosed by the invention, the problems that the silybum marianum is likely to be in excessive growth, plants are too high, the inflorescences are few and inconsistent in maturity, and the mechanical harvest is not convenient can be effectively solved, and the effects that the plants of the silybum marianum become short, the inflorescences are neat, the mechanical harvest is facilitated, the number of the inflorescences is increased, and the fruit yield is increased, are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of crop chemical regulation, and in particular relates to a chemical regulation method of milk thistle. Background technique: [0002] Milk thistle is an annual or biennial herb of the genus Milk thistle in the family Asteraceae. It is an excellent liver-protecting plant. The whole plant is used for carbuncle and erysipelas. Lower blood fat, protect heart muscle, protect brain, anti-X-ray function, have good curative effect on acute and chronic hepatitis, liver cirrhosis, fatty liver, liver injury caused by metabolic toxicity, cholelithiasis, cholangitis and perihepatic cholangitis and other hepatobiliary diseases . Milk thistle likes a cool and dry climate, has strong adaptability, and does not have strict requirements on water and fertilizer conditions. It is planted in a large area in the northeast, north, and northwest regions of China. The northeast region is the main production area of ​​milk thistle...

AI Technical Summary

Problems solved by technology

[0006] It is necessary to solve the current problems that the main inflorescence of milk thistle is too high, the maturity period of each branch inflorescence is different, and the field loss after fruit ripening is not conducive to large-scale mechanized harvesting; the vegetative growth of milk thistle is too vigorous, and the production potential cannot be realized. To solve the problem of yield improvement, the technical method of the present invention is specially provided
