First, renovation of the water system It has entered the rainy season and flooding has occurred from time to time. In this regard, all localities must learn from the experience and lessons learned from the serious waterlogging disasters of cotton. They should stand up to disasters, attack clear channels, refurbish water systems, and effectively raise the standards of water systems in the cotton fields in order to reduce flood damage. Second, remove the leaves Hybrid cotton is not not pruned; leaves are not as good as possible. To change the extensive management method of planting hybrid cotton without pruning or eradicating buds, except for the lack of density, the cotton field can be appropriately selected to retain 1-2 robust leaf branches in the vertical direction, and other cotton fields should grab sunny leaves as soon as possible to remove excess leaves. Axillary buds. The leaves that you choose to stay must also fight at the right time. Third, loose soil roots It is necessary to loosen the soil and weed, remove the soil compaction, improve soil permeability, promote root development of cotton seedlings, and accelerate the growth of cotton. To combine weeding with weeds, do a good job of rooting. To practise soil, do not use ploughs to plough and cultivate the soil, form high-quality cotton field strips, and increase cotton's ability to resist wind and lodging. To promote the elimination of cotton fields, it is necessary to select suitable drugs and regulate the use of drugs. Fourth, control pests It is necessary to correct the fuzzy understanding of insect-resistant cotton not to control pests, and to prevent and control the occurrence of blind stink bugs, red spiders and aphids in cotton fields in a timely manner to provide guarantees for shaping high light-efficient plant types and high-quality groups; and to closely monitor the occurrence of cotton bollworms, Whether it is conventional cotton or insect-resistant cotton, as long as it meets prevention and treatment standards, it must be promptly used to prevent and control the harm. Fifth, increase the hair frame fertilizer For deficiencies in base fertilizers, unfertilized cotton fields after transplanting, or cotton fields with slow growth and weak seedlings, additional fertilizers should be applied to promote the rapid transformation of cotton, fast-growing trees, and rapid construction. The cotton field that has been applied with basal fertilizer and cotton seedlings must have enough fertilizer, and the first flower and bell fertilizer should be used in time after flowering. To overcome the idea of ​​light nitrogen fertilizer and light potassium fertilizer, no additional potassium fertilizer or insufficient potassium fertilizer is used in the base fertilizer. Potassium fertilizers; cotton fields with large row spacing and low density should be applied with flower and bell fertilizers in a timely manner; methods should be adopted for furrows; nitrogen fertilizer, potash fertilizer, and organic fertilizer should be combined on fertilizer types; and high-quality compound fertilizers should be promoted. If boron fertilizer is not applied in basal fertilizer, appropriate amount of boron fertilizer should be applied. Sixth, disaster recovery Storms cause the lodging of cotton, and it is necessary to support them in time; storms cause flooding of cotton fields, and timely drainage and drainage; hail disasters damage cotton seedlings. In addition, it is necessary to make timely adjustments due to seedlings.

Summer cotton boll management?
Summer is a crucial period for cotton to stand up to a high yield and shape individuals with high light efficiency. Therefore, the management of cotton fields should focus on the promotion of fast-growing cotton trees, stable structures, long health care, increased branches, increased growth and strengthening of buds, prevention of droughts, floods, sudden changes, disaster prevention, strain management, and the following key measures.
