Problems solved by technology

Currently, the ripening agents in the market are mainly thiadizuron and ethephon series. These products are mainly used in the middle and late stages of boll opening, when the boll opening rate reaches 40% (generally in the middle and late September), so as to speed up the boll opening process. To achieve the purpose of concentrated boll opening, if used in advance, it will affect the function of cotton leaves, reduce photosynthesis, and affect cotton yield and quality

Abstract

The invention discloses a cotton flower-promoting and ripening agent and a flower-promoting and ripening method, and belongs to the technical field of cotton planting. The cotton flower-promoting and ripening agent is composed of a component I and a component II, wherein the component I is composed of sorbitol and gibberellin; and the component II is composed of brassinolide, mepiquat chloride and isoflavone. According to the flower promoting and ripening method, the component I and the component II are sprayed in different periods, the flowering period is shortened, then the cotton boll ripening time difference is reduced, the purpose of concentrated boll opening is achieved, and the agent has good application and popularization value.

Description

technical field [0001] The invention relates to the field of cotton planting, and specifically provides an agent for promoting flowering and ripening of cotton and a method for promoting flowering and ripening. Background technique [0002] Cotton is an important economic crop and strategic material in our country, and has an irreplaceable important position in the national economy. With the improvement of the level of mechanization, cotton harvesting by machine has become an important way to reduce the labor and improve the efficiency of cotton planting. The boll-opening period of cotton is about 60-70 days from mid-late August to late October or early November. The boll-opening period is too long, which is not conducive to mechanical harvesting. Sometimes it takes 2-3 times to complete the harvest. The application of ripening agent can regulate the reasonable growth and development of cotton, construct the reasonable plant type and population structure of cotton, promote ...
