[0004] Chinese patent ZL201010237770 discloses a cotton flower bud differentiation agent, which can promote early maturation and concentrated maturation of cotton, but this new chemical regulator is mainly used for spraying, and the use period and amount of use are not perfect. The purpose of the present invention is to provide a new The chemical regulator and its preparation method and light and simplified use method, according to the standardized plant type and ripeness regulation curve obtained from many years of experiments, rationally arrange the chemical regulation time and dosage, so as to ensure that the cotton production is satisfied while greatly reducing the machine into the field. The number of times and labor input, thereby improving the efficiency of cotton planting

Abstract

The invention relates to a cotton growth regulating agent and a preparation method and application thereof. Active ingredients of the cotton growth regulating agent include naphthylacetic acid, triacontanol, triodebenzoic acid, 6-BA (6-benzylaminopurine), uniconazole, a dispersing agent, a wetting agent, ethylene glycol, glycerin, gibberellins and indoleacetic acid. The cotton growth regulating agent is capable of promoting cotton precocity and concentrated maturity and can be used by either spraying or drip irrigation, and labor input is effectively reduced. According to cotton standard maturity and plant type regulation reference graphs, cotton growth indexes are inspected to realize quantified regulation in two periods in contrast to a standard plant type and a maturity curve, and adverse influences of risks of cotton yield reduction, runt seedlings and the like caused by spraying of mepiquat chloride in a cotton seedling stage due to improper traditional experience based chemical control can be avoided.

Description

technical field [0001] The invention belongs to the technical field of cotton planting, and in particular relates to a cotton growth regulator and its preparation method and application. Background technique [0002] Cotton is an important economic crop and raw material for textile industry in my country, and occupies an important position in the national economy. Premature senescence or late maturation of cotton is a major obstacle that restricts high-yield and high-efficiency cotton and farmers' increase in production and income. In recent years, a large area of ​​cotton in Xinjiang cotton region, the most important cotton region in my country, has been late-maturing, resulting in serious yield loss. According to the survey, the cotton fields with reduced cotton production and income due to improper regulation of maturity accounted for about 20% of the cotton planting area. The key to maturity control measures is the time and amount of control. Therefore, the maturity r...
