Problems solved by technology

The active ingredient of the herbicide-type defoliant is herbicide, although it can achieve the purpose of defoliation to a certain extent, it has a direct killing effect on cotton, while the hormone-regulated defoliant has little damage to cotton while defoliation, but Its residues pollute the soil and pollute the environment

Abstract

The invention discloses an efficient cotton defoliating agent and a synthesis method thereof. The defoliating agent is prepared from, by weight, 20-40 parts of ethephon, 10-20 parts of magnesium chlorate, 10-25 parts of thidiazuron, 12-22 parts of coronatine, 8-15 parts of polycondensated naphthalenesulfonate, 2-6 parts of carrageenan, 10-20 parts of moist organosilicon auxiliary, 15-20 parts of sodium lignin sulfonate, 8-17 parts of hydroxyquinoline, 3-10 parts of ethylene glycol and 35-55 parts of deionized water. The preparation process is simple, the prepared defoliating agent can improve the cotton defoliating rate, is not harmful to cotton and has environment-friendly and non-toxic effect. In addition, the residues of the efficient cotton defoliating agent do not cause soil pollution.

Description

technical field [0001] The invention relates to the technical field of defoliant preparation, in particular to a high-efficiency cotton defoliant and a synthesis method thereof. Background technique [0002] Cotton is the seed fiber of the Malvaceae cotton plant, native to the subtropical zone. The plant is shrubby and can grow up to 6 meters high in tropical areas, generally 1 to 2 meters. The flowers are milky white, turn dark red shortly after flowering and then wither, leaving small green capsules called cotton bolls. There are cottonseeds in the cotton bolls, and the fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the cotton bolls mature, they crack, exposing soft fibers. The fibers are white or white with yellow, about 2 to 4 cm long, containing about 87-90% cellulose. [0003] At present, the main mechanisms of cotton defoliants used are divided into: herbicide-type defoliants and hormone-regulated defo...
