Problems solved by technology

[0006] At the same time, before and after budding of cotton is the critical period of boron nutrition, the lack of boron nutrients will lead to a decrease in the number of pollen and falling flowers and buds and peaches, which will aggravate the problem of premature aging
[0007] Although the field has formed a certain understanding of the premature aging mechanism of cotton, so far, an ideal technical solution for solving the premature aging problem has not yet been formed.
Existing research usually directly solves pathological premature aging, but does not pay attention to long-term nutritional deficiency, especially the persistent premature aging of cotton caused by insufficient nutritional supply in the later stage and insufficient nutritional supply in the middle and upper parts. Chitosan oligosaccharide is used for anti-premature aging purposes and methods just there is above-mentioned defect

Abstract

The invention discloses a compound agent for preventing and controlling premature senility of cotton, which is composed of solid powder and a liquid preparation, wherein the solid powder comprises borax, urea and potassium dihydrogen phosphate; and the liquid preparation is an ethanol solution of brassinolide. The compound agent can improve the biological activity of the cotton plant and increase the nutrient supply in the cotton growth process, thereby maximally solving the problem in preventing and treating premature senility of cotton and obviously enhancing the ultimate yield of cotton.

Description

technical field [0001] The invention relates to a compound agent, in particular to a compound agent capable of preventing and controlling premature aging of cotton, and belongs to the field of pesticides. Background technique [0002] With the popularization and application of transgenic insect-resistant cotton, the insect-resistant performance of cotton has made significant progress, but with it, the proportion of cotton voltaea has increased, the growth process has advanced, and premature aging has become aggravated, which has become a constraint to the development of cotton production. Key factor. In the year of mild premature aging, the yield reduction of seed cotton per hectare can reach 225kg-300kg, causing economic losses of about 7.5 billion to 10 billion yuan in my country, and the loss in the year of severe premature aging will exceed 15 billion yuan. [0003] Cotton premature senescence, that is, "premature senescence", is a phenomenon that due to self or externa...
