Cotton growth control measures
Accelerate the transformation of fast and weak seedlings When farmers transplant cotton seedlings, there is no time to apply basal fertilizers. Some fertilizers are used in small quantities. Some apply ammonium bicarbonate, do not apply phosphorus and potassium fertilizers, and do not apply trace elements such as boron and zinc to make cotton seedlings. Earlier, there were different symptoms of de-fertilization. At present, we should focus on main buds and flower-fertilizers, increase the use of commodity organic fertilizers, high-content multi-component fertilizers, and apply micronutrients. Each acre should be applied 50 kg of organic fertilizer and 25~30 kg of high-content compound fertilizer. The severe nitrogen deficiency tops 10~15 kg of urea per acre. Potassium fertilizer should be increased by 10 kg per kilogram of soil that lacks potassium. Boron-poisoned cotton field supplemented with 0.4 kg of boron, and after flowering, it was sprayed with 0.1%~0.2% of Sonic Boron 1~2 times.
Controlling Plant Types Striving for Stable Growth According to many years of observation, the peak period of cotton vegetative growth in the southern cotton region appeared from late June to early July. Some farmers this year, due to over-application of nitrogen fertilizer or over-fertilization, resulting in cotton growing too fast. The retarded plant growth regulators, tarilotine or mepiquat, should be applied immediately to control the growth of cotton plants. The use of 5 ml of melatonin per kilogram or 1 kilogram of salicylamine against 15-20 kilograms of clean water can be used to delay the growth according to the growth of the cotton using a small number of times. According to the actual effect of Wangwang, the amount can be appropriately increased to create a high-yield environment for the cotton to gradually create a “seamless seal (line), a middle seam, sunlight shines, and air circulationâ€, in order to stabilize the cotton and shape it. The ideal high yield plant type.
Adhering to Resilience to Improve Responsiveness During the budding and flowering of cotton, the south coincides with the rainy season, and waterlogging may constitute damage to cotton production at any time. While we are trying to promote small-scale development, control and stability, and balanced growth, we must Maintain well drainage and irrigation facilities, clean up the ditch, arrange bright and dark spots, and ensure the normal development of the root system. For cotton that suffers from waterlogging, phytotoxicity, and fertilizer damage, 0.01% Balsam (endosin lactone) or Tinfengsu EC 10ml against fresh water 15~20kg can be sprayed 1~2 times, or 0.05% Spraying the "920" solution can effectively promote transformation and gradually restore normal fertility. In cotton fields where there is a large amount of fertilizer loss, urea or high-content compound fertilizers should be applied in a timely manner as appropriate.
