When will the cotton peach fertilizer be used?

When will the cotton peach fertilizer be used? Please introduce cotton to apply peach fertilizer is not afraid of cotton growth. Some farmers are worried that after the application of peach fertilizer, they are afraid of causing the "secondary growth" of cotton, greedy for green and late ripening. In fact, this kind of worry is superfluous. First, after the cotton is concentrated on the peach, the direction of nutrient transport is shifted from the growth point of the main stem to the fruit branch of the peach, and the cotton boll has the bearing capacity and will not cause "secondary growth"; second, the flowering and boll setting period is the second peak of carbon content in the cotton plant, the nitrogen content decreases, the soluble sugar content increases, the proportion of carbon to nitrogen is the largest, and the nutrients required are the most, only afraid of starving seedlings and not afraid of crazy growth. Third, the middle and upper part of cotton is well ventilated and transparent, and the peach rate can be as high as 50%, which is more than 10% higher than that of the lower part. With enough fertilizer, cotton can be stable and unfailing. Attention should be paid to improving the technology of applying peach fertilizer. First, change the supplementary application of peach fertilizer to universal application of peach fertilizer, renew the concept of applying peach fertilizer; second, change the light application of peach fertilizer before the Beginning of Autumn to increase the amount of peach fertilizer before and after the Beginning of Autumn, generally applying 15 kg of urea per mu. Take measures according to seedling conditions, flexibly control the time of fertilization; third, change sprinkling to point application, change dry application to soil moisture fertilization, timely irrigation and adjust fertilizer with water; fourth, if there is rainfall after fertilization, depending on the seedling situation, spray delayed plant growth regulator mepiramine or zhuangxin, 4-5 grams or 16-20 milliliters per mu, 40-50 kilograms of water. Those with no trend of prosperity and growth do not need to be sprayed. Click to get more cotton planting technology click to get more food crop planting technology
