Defoliation ripener used for cotton

Abstract

The invention provides a defoliation ripener used for cotton, which comprises thidiazuron, diuron and ethephon with mass ratio of 1-95: 0.1-40: 10-70. The defoliation ripener used for cotton has the functions of defoliation and acceleration of maturation after the ripener is used on cotton, and the yield for the cotton is not reduced.

Description

technical field [0001] The invention relates to the field of agricultural chemicals, in particular to a defoliation and ripening agent for cotton. Background technique [0002] Cotton is the most widely used textile fiber and is planted in most areas of our country. As a cash crop, it plays a pivotal role in our national economy. Cotton has the habit of unlimited flowering. It takes a long time from the beginning of flowering and boll formation to the end of flowering and boll formation. It takes about 50-70 days from flowering to boll opening. Therefore, the boll stage of cotton on the same bead is quite different. Due to reasons such as climate or cultivation techniques, some cotton bolls often fail to mature normally before frost, and become post-frost flowers or unopened bolls, thereby affecting the yield and grade of cotton. Under normal circumstances, before the cool period, due to climate change and lower temperature, cotton will basically stop flowering and boll for...

Problems solved by technology

[0003] At present, the commonly used cotton defoliants only defoliate without ripening, and are extremely sensitive to temperature. Low temperature has no defoliation effect, and it will also reduce cotton yield, and the cotton boll weight will decrease by 0.2-0.5g
