Cultivation method for controlling height and shaping by dripping mepiquat chloride in cotton field

The invention discloses a cotton field mepiquat chloride drop-application height-control shaping cultivation method, which utilizes an under-film drip irrigation system, not only does not increase manual and mechanical energy consumption, but also reduces chemical control by 1-2 times, and by dropping different amounts of mepiquat chloride in different growth stages of cotton, cotton plant height is controlled and a shaping effect is achieved. According to the method, spraying is replaced with the mode that mepiquat chloride is applied along with water drops, cotton plant damage, lodging, indirect disease and insect pest propagation, mechanical energy consumption and the like caused by spraying can be reduced, the method is more convenient, simpler and more energy-saving, the purpose of controlling height and shaping is achieved, production requirements are met, practicability is high, and application and popularization are facilitated. 本发明公开了一种棉田缩节胺滴施控高塑型的栽培方法，利用膜下滴灌系统，既不增加人工和机械耗能，又减少化控1-2次，通过棉花不同生长阶段滴施不同量缩节
