Abstract
The invention belongs to the technical field of agricultural production, and relates to a novel cotton topping technique. Manual topping is an important process in cotton field management, and is high in work load and poor in work efficiency. Suckering agent, Flumetralin (Mie Ya Ling), special for tobacco is introduced, mixed liquor of 0.42%.-0.83%. Flumetralin solution and 0.27%. nutrient solution is sprayed to cotton during cotton topping, and by using the Flumetralin compared with normal manual topping, cotton plants grow vigorously, leaves are thick green, cotton plants are dwarf, fruit branches are reduced slightly, cotton seed index is increased, lint percentage is slightly reduced, single-plant bolls are increased, boll setting rate is increased slightly, and single-boll weight is increased. When the concentration of Flumetralin is 0.33%.-0.83%., all treatments have yield increase effects to different degrees. When the concentration of Flumetralin is 0.83%., yield is increased by 14% preferably. By the Flumetralin spraying technique, manual topping load can be reduced, yield is increased, and change of quality characters is not obvious. Manual topping can be substituted by Flumetralin spraying, so that cotton planting benefit is increased, and cost is lowered.
