Problems solved by technology

[0005] At present, there is no plant growth regulator that can not only promote cotton maturation but also effectively promote cotton defoliation. In actual production, people mainly use ethephon and ethephon paraquat water agent for cotton ripening, and ethephon water The ripening effect on cotton is relatively slow, and the use of ethephon·paraquat water agent can improve the ripening effect, but the two agents cannot effectively defoliate cotton, affect the harvest rate, and cause a decrease in cotton grade; use thiophene. Benuron promotes cotton defoliation, which is beneficial to increase the rate of mechanized harvesting, but cannot effectively increase the proportion of pre-frost flowers

Abstract

The invention relates to a growth regulator of a combination cotton of thidiazuron and ethephon, which is characterized by comprising the following components according to weight percentage: 45 to 90 percent of active ingredients of the thidiazuron and the ethephon and residual addition agent, wherein, the weight ratio of the thidiazuron and the ethephon is 1:2.5 to 5. The invention adopts osmotic agent of the addition agent, solid carrier, wetting agent and dispersant, etc. commonly used in the agricultural chemical field to be made into wetting powder formulation, the formulation can be used as plant growth regulator for the ripening and defoliation of cotton. The growth regulator of the invention has the advantages of good effects on the defoliation and ripening of cotton, improving the grade of cotton, increasing the output of cotton, especially the output before frost and improving the benefits of farmers.

Description

technical field [0001] The invention relates to a cotton plant growth regulator composition, which is a plant growth regulator for defoliation and ripening of cotton before the cotton is harvested before frost. The invention belongs to the technical field of plant growth regulators. Background technique [0002] Cotton is the most widely used textile fiber, and it is planted in most parts of our country. As a cash crop, it plays a pivotal role in the national economy. Cotton has an infinite flowering habit, and it takes a long time from the beginning of flowering and boll formation to the end of flowering and boll formation, and it takes about 50-70 days from flowering to boll opening. Therefore, the boll stage of cotton on the same cotton plant is quite different. Due to climate (especially in the northern cotton area) or cultivation techniques, some cotton bolls often fail to mature normally before frost, and become post-frost flowers or unopened bolls, thereby affecting ...
