Abstract

The invention discloses a cotton defoliation compound and a preparation method thereof. The defoliation compound contains the following components in parts by weight: 15-30 parts of ethephon, 10-20 parts of naphthylacetic acid, 8-15 parts of simethicone, 5-10 parts of coronatine, 8-20 parts of abscisic acid, 2-6 parts of glycol, 10-20 parts of sodium lignin sulfonate, 8-15 parts of poly-condensed naphthalene sulfonate, 5-10 parts of nonyl phenol polyoxyethylene ether, 5-10 parts of zinc sulfate, 1-4 parts of nanometer silver ion powder and 20-30 parts of deionized water. According to the invention, the technology is simple; the prepared defoliation agent can increase the defoliation rate of the cotton, is harmless to cotton, is capable of effectively reducing impurity content and is capable of increasing the cotton fiber quality; besides, the residue thereof cannot pollute the soil.

Description

technical field [0001] The invention relates to the technical field of preparation of defoliants, in particular to a cotton defoliation composition and a preparation 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 ...
