Timely fertilization in the cotton ringing period can prevent premature aging and increase production
At present, it is the flowering and ringing period of cotton, and it is also the peak period of cotton fertilizer. At this time, if the fertilizer can't keep up, the cotton will prematurely decay due to de-fertilization, causing the buds to fall off a lot, resulting in a substantial reduction in production. Therefore, for cotton fields with insufficient base fertilizer or less top dressing, three fertilization measures should be taken. Drought and flood prevention, such as the weather forecast, no rain in the near future, should be watered immediately, to be separated by the ditch, avoid flooding with large water, to prevent guilt caused by rain after watering. After watering, timely shallow cultivating, breaking the soil compaction, is conducive to protection. After the heavy rain, discharge the water in the field in time, no more than 24 hours at the latest. The best time to replenish the top-loading fertilizer and topdressing in time is after the topping in August. 5 to 7.5 kg of urea per mu, combined with cultivating and cultivating soil, applied between the large rows of cotton, the depth is 10 cm, about 15 cm from the cotton plant. This topdressing has a significant effect on cotton growth and anti-premature aging. The timely spraying of foliar fertilizer should start from the top of the top, and spray at the latest before the fall, which has obvious effects on preventing premature aging, reducing shedding and increasing boll weight. Can be sprayed with potassium dihydrogen Phosphate, Ai Nong and other foliar fertilizers; or sprayed with 1% to 2% urea solution + 0.3% potassium dihydrogen phosphate solution; or sprayed with 1% urea solution + 2% phosphate fertilizer leachate; It can be sprayed with 1% urea solution + 2% phosphate fertilizer leachate + 2% potassium chloride solution.
