Problems solved by technology

[0003] At present, the mechanism of the main cotton defoliants used is divided into: herbicide-type defoliants and hormone-regulated defoliants. The active ingredient of herbicide-type defoliants is herbicides. However, it has a direct killing effect on cotton, while the hormone-regulated defoliation agent has little damage to cotton while defoliation, but its residue pollutes the soil and pollutes the environment

Abstract

The invention discloses a synthesis method for a cotton defoliant. The defoliant is prepared from, by weight, 20-40 parts of ethephon, 20-50 parts of magnesium chlorate, 15-25 parts of paclobutrazol, 10-15 parts of coronatine, 10-20 parts of pyraflufen-ethyl, 2-6 parts of carrageenan, 15-20 parts of sodium lignosulphonate, 5-12 parts of sodium carboxymethylcellulose, 2-6 parts of nano-silver ion powder and 25-45 parts of deionized water. The preparation process is simple, the obtained defoliant can increase the cotton defoliation rate, is harmless to cotton and has the advantages of being environmentally friendly and free of toxicity, and residues of the defoliant will not contaminate soil.

Description

technical field [0001] The invention relates to the technical field of preparation of defoliants, in particular to a method for synthesizing cotton defoliants. Background technique [0002] Cotton is the seed fiber of the Malvaceae plant. It is native to the subtropical zone. The plant is shrubby. It can grow up to 6 meters high when cultivated in the tropics, generally 1 to 2 meters. The flowers are milky white and turn dark red shortly after flowering. Then it withers, leaving a small green capsule called cotton boll. There are cottonseeds in the cotton boll. The fluff on the cottonseed grows from the skin of the cottonseed and fills the inside of the cotton boll. When the cotton boll matures, it cracks to reveal soft fibers, which are white or white. Yellowish, about 2 to 4 cm long, containing about 87-90% cellulose. [0003] At present, the mechanism of the main cotton defoliants used is divided into: herbicidal defoliants and hormone-regulated defoliants. The active in...
