At present, cotton has entered the stage of Sheng Lei. The bud-bell period is a key period for the growth and development of cotton, and it is also a period of natural disasters such as diseases, insects, droughts and locusts. All localities should aim at the current climate characteristics and growth trend, strengthen management according to local conditions, timely topdressing and watering, and do a good job in pest control. Promote the combination of control and fight for more knotted peaches and early autumn peaches. To this end, the following field management technical guidance is proposed.
After the cotton film is removed from the cultivating soil, the soil is easy to be knotted, the soil moisture is accelerated, and there are many weeds. It is necessary to carry out cultivating loose soil, break the knot and eliminate weeds. In the bud stage, combined with cultivating, cultivating soil and spraying 600 times of new high-fat film to form a layer of physical polymer film to reduce water evaporation and prevent infection.
If there is no rain in the management of water and fertilizer (see the water in the ground after the rain), the cotton field should be watered to prevent premature aging. Cotton fields with insufficient base fertilizer need to be combined with watering or rain to apply urea. Foliar spraying of photosynthetic nutrient film fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. One-year benefits for one application.
The regulation of pruning promotes the simplification of pruning, and advocates the retention of leaf branches. When the main stem of the cotton plant sees the flower, the tip of the leaf branch is removed; the empty plant and the empty branch should be removed in time to improve the ventilation and light transmission conditions.
The scientific control of Wangchang cotton field can be sprayed on the promotion of Huawang No. 3 before the prolonged period, which can promote the transmembrane signal conversion of plant cells, forcing the toppings to vigorously return a large amount of nutrients, and the inertia advantage of the tip is rapidly weakened to the capping situation. The main nutrient of the trunk turns to the young fruit development system, which enhances the fruit's swelling vitality, avoids the phenomenon of leaf hypertrophy, and improves the field permeability.
Prevention and control of pests and buds is a period of frequent pest and disease in cotton fields. It is necessary to increase monitoring efforts and make full use of various media to timely and accurately publish the dynamics of pests and diseases and prevention and control information. Spraying new high-fat membranes before the onset of disease can automatically form a layer. The polymer protective film that is invisible to the naked eye optimizes the water absorption, air permeability and light transmission quality of the plant. Blocking pests and smuggling signals and weakening the media to resist and defend against natural environmental disasters. After the onset of the disease, timely use with a highly targeted agent to control the effect is good. (Yellowstone)
