How to control the cotton effect is good:
1. If the cotton seedlings have different symptoms of de-fertilization earlier, the main attack buds and flower fertilizers should be applied, and the commercial organic fertilizer, high-content multi-component compound fertilizer, and micro-fertilizer should be added. Foliar application of foliar fertilizer and 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.
2. At the peak of vegetative growth of cotton in the southern cotton area, due to partial application of nitrogen fertilizer or excessive fertilization, cotton may grow too fast. The delayed plant growth regulator ketamine should be immediately applied to control the cotton plant topping agent to control the length of the cotton plant. The assimilation induction promotes the transmembrane signal transduction of plant cells, forcing the toppings to vigorously recirculate a large amount of nutrients, and the inertia advantage of the tip is rapidly weakened to the capping state. 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.
3. During the bud and flowering of cotton, the southern part coincides with the rainy season, and the waterlogging can constitute damage. While grasping the small and catching up, controlling and seeking stability, and balancing growth, it is necessary to clean up the ditch, and arrange the rafts and descending. Dark stains ensure that the roots develop normally. For cotton that suffers from waterlogging, phytotoxicity and fertilizer damage, cotton Zhuangting and new high-fat membranes can be sprayed to activate the positive energy of plant ecological growth, broaden the plant conduit path, increase the water absorption and fertilizer absorption of plants, and gradually resume normal fertility. For cotton fields with more fertilizer loss, apply urea or high-content compound fertilizer as appropriate.
