In order to ensure that the top of the peach leaves is covered, premature aging of the cotton is prevented, boll weight is increased, and the cotton yield and income are increased. Various forms of posterior propaganda and training measures for the cotton are used to strengthen the post-phase cotton water and fertilizer operations, pest and plant protection, chemical regulation, and foliage. Various measures such as surface fertilization were put in place in time to ensure the steady growth of cotton, and effective measures were taken to comprehensively lay out the cotton field management in the later period.
Specific field management measures:
1, pay attention to water and fertilizer regulation: a reasonable adjustment of the late cotton water and fertilizer operations, timely stop fertilizer in mid-August. In the management of the water, the cotton field is free from drought and wilting, keeping the cotton field moist. As the cotton field grows in time, it is important to stop the water too early. The water stop time is generally from the end of August to the beginning of September.
2, rational control and artificial regulation. Effectively strengthen the control work, and pay close attention to the cotton that is already growing. For the secondary growth, axillary buds, lateral branches are still flowering cotton fields for heavy control, control of vegetative growth. Too much growth in shaded or overgrown cotton fields should be implemented by pushing plants and ridges to increase ventilation and light transmission in the cotton fields, prevent rotten bells, and promote early maturing.
3, to strengthen the prevention and treatment of pests and diseases in the late cotton field. Strengthen the prevention and control of pests and diseases, adhere to the principle of “prevention first, comprehensive prevention and controlâ€, strengthen the prevention and control of cotton bollworm, red spider, and cotton aphid, pay close attention to field comprehensive prevention and control to ensure the stable growth of cotton; at the same time, do a good job in the prevention of verticillium wilt in cotton fields. jobs.
4, to prevent premature aging or bulimia cotton fields. For premature aging cotton fields, potassium dihydrogen phosphate was sprayed as soon as possible, and supplemental water and horse water were added. For greedy green cotton fields, artificial pruning, heavy chemical control, and early water stoppages are taken.
5, combined with reviewing group tips, clearing field weeds and other seedlings, to maximize utilization of water and fertilizers, and promote the rapid and stable growth of cotton.
