In view of the current situation of complex cotton seedlings, in order to promote balanced growth and enhance stamina, corresponding measures should be taken to classify and guide, strengthen management, and strive to resist harvesting.

First, grab the season, quickly make up the fat. Appropriating topdressing fertilizers is the main contradiction in cotton management, but it must be implemented in categories. For the cotton that has been flowered and belled, the application of flower and bell fertilizer should be applied. Apply 15 kg of compound fertilizer, 10 kg of urea and 15 kg of potassium fertilizer per mu; apply 2000 to 2500 kg of rotten organic fertilizer per mu for cotton entering the bud stage. 50 kg of organic compound fertilizer, 15-20 kg of inorganic compound fertilizer, 15 kg of potassium fertilizer, 10 kg of urea in addition to severe defertilization, and the application of urea or ammonium bicarbonate to cotton that has not yet budded. Rapid transformation and upgrading; for boron deficiency, serious recovery of 200 to 250 grams of boron per mu, and spraying 0.2% of Sonic boron 2 or 3 times.
Second, the cultivator breaks the board and eliminates weeds. After the rain, cotton fields are generally hardened, affecting the development of cotton roots. One is to grab the sorghum when it is artificially grabbed, the other is that large cotton-growing families can use mechanical cultivators to cultivate the soil quickly, and the third is chemical weeding. The directional spray can be used to spray cotton widely. Apply 10% glyphosate or 20% paraquat, the former 300 to 400 milliliters per acre, the latter 200 to 300 milliliters per acre, 6 weeds above the appropriate increase in the amount of weeds. After application of such herbicides, in case of drought, avoid flooding.
Third, prolonged prevention and attention to insect pests. After the topdressing of cotton, in the event of medium-intensity rainfall, it is very prone to prosperous and even mad. The choice of plant growth regulators should be delayed modest melatonin or dihydamine as well, at this time the dosage can be used every 3 to 6 milliliters of methocarbazine or salicylamine 1.5-2 grams, rather a small number of times, not blindly Increase the dosage. In recent years, some farmers have increased their consumption, although the cotton plant height has been controlled, and the bellicidal nature can be drastically reduced. This lesson should be learned. Insect pests, brunt of the blind or blind, should be used to control blind lice, 2% emamectin benzoate, 5% fipronil suspension agents.
