1. Strictly control the use conditions. The ketamine is suitable for cotton fields with good fertilizer and water conditions. The weather is dry and the cotton fields that cannot be used for irrigation are not suitable for use. When cotton fields are damaged and natural disasters are inhibited, growth cannot be used.
2, control the amount of medication should not be greedy, should not be used in large quantities, especially in the seedling, bud and initial flowering period to strictly control the dose. If the plant grows slowly, the fruit branches are shrunk together, and the leaves do not open, causing a large number of buds to fall off, and the yield reduction is quite serious. In this case, gibberellin (920) can be sprayed in time, which has a significant effect on relieving this symptom and restoring growth.
3, pay attention to the use of water and fertilizer combined with the use of ketamine to pay attention to fertilizer management, with appropriate, must not be due to deepening of the leaves after application, and neglect fertilization and watering.
