Eight institutes such as the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, based on the habit of unlimited growth of cotton, use artificial to go to early buds on the basis of early-onset cotton, and use the growth-adjustment patch-shrinkage spray to spray late fruit-tree growth points to control late growth. Lei, which promotes the concentration of multi-kidney peaches and early autumn peaches in the most-associated bolls, increases the percentage of oats and peaches by 10-20%, increases the pre-frosting flower rate by 10%, and decreases the rotten bell by 30-50 %. The grade of cotton is increased by 0.5-1. Specific technologies include:
(1) To early buds: The main method is manual removal. The number and time of buds depends on the degree of premature emergence of cotton plants. Generally, it is advisable to use 4-8 buds on the lower 1-4 fruit branches of the cotton plants, but it is not necessary to go to the buds and leaves. The time is from June 20 to 30. The number of buds must be determined by the growth of cotton plants. Bud early cotton plants can go to 8 buds, if the bud is less late to go a few.
(2) In addition to (controlling) the late buds: the growth buds are the main ones, but laborious places can also use artificial methods to hit the tip of the upper fruit branch. The cotton plant is topping on August 5th. When the upper fruit branch grows 2-3 fruit sections, use the shrinkage section to set 3-5 grams per mu and dilute the water to 50 kg. Spray the upper fruit branch growth point for chemical capping control. bud. In order to realize the effect of increasing the output of early and late buds, it is necessary to combine appropriate close planting, chemical control, reasonable fertilizer management and pruning and other supporting technologies.
Promotion and application areas: Huang-Huai-Hai Plain and the Yangtze River Basin cotton area.
