Recommendations: 1. Strengthen the removal of residual film in cotton fields during land preparation. Intensive cultivation can effectively improve the emergence rate of cotton fields; 2. Before sowing, cotton fields must be sprayed and sealed with herbicides. Method: The herbicide is mainly made of 150-180g of pendimethalin mixed with 40-50kg of diluted liquid per acre. The amount of water sprayed must be enough, and the dosage should be strictly in accordance with the instructions; 150g of trifluralin EC mixed with 40-50kg of water/acre. Mu of diluted spray cotton fields were sealed. 3. When sowing, manual work must be strengthened to follow the machine. When the seeder leaks the film, workers should compact it with soil in time to avoid blowing up the film when the wind comes, affecting the emergence of cotton seedlings.
