At the beginning of the season, due to the influence of the outside weather, cotton field management should do the following work:
1. Drain the ditch to prevent the cotton field from being stained. Dredge and deepen the surrounding ditch of the cotton field, and dilute the ditch. If the field is long, pay attention to opening the middle ditch. After the rain, strengthen the management of fertilizer and water, and spray a new high-fat film to protect the fertilizer and enhance the resistance of the cotton plant.
2. In order to transfer the nutrients of the plants to the reproductive organs of cotton plants and control the cotton beads to grow wild, the flowering of the flowering flower No. 3 should be sprayed in time to inhibit the plant growth and promote flower bud differentiation. It can also effectively improve the ventilation and light transmission conditions of cotton fields and reduce the consumption of nutrients.
3, suitable for soil cultivation, timely ploughing loose soil, enhance ventilation. It is necessary to spray cotton Zhuangting in the flower bud stage, young fruit stage and expanded peach stage , which can strengthen the strong buds, make the cotton nutrient conveying conduit thicker, enhance the expansion of the cotton bud, and improve the high-quality cotton blasting rate and yield.
4. Strengthen pest control. More rain, more aphid occurrence, prone to blight. High-efficiency pesticides such as enemy killing can be used for prevention and control, and new high-fat membranes can be sprayed to enhance the efficacy and improve the utilization rate of the active ingredients of the medicament.
