How to fertilize black sugarcane for high yield

How can black sugarcane be fertilized for high yield? Please guide the black-skinned sugarcane to enter the late growth stage and basically stop growing, and many growers think that re-fertilization is useless. In fact, black-skinned sugarcane is the most important period for sugar accumulation in the late growth period. According to the investigation, the yield of black-skinned sugarcane can be increased by about 15% if the strong tail fertilizer is applied in time in the later stage of black-skinned sugarcane growth, so that the leaves remain thick green and the sugarcane tail does not become smaller. Therefore, it is necessary to apply black sugarcane strong tail fertilizer in time. The specific application methods are as follows: in the late growth stage of black-skinned sugarcane, that is, in the middle and late October of each year, Zhuangwei fertilizer was applied, mainly quick-soluble nitrogen fertilizer and potassium fertilizer, and appropriate application of magnesium fertilizer and boron fertilizer. Per mu, the application of high nitrogen and high potassium nitrogen, phosphorus and potassium (20m ~ 5m ~ 20) compound fertilizer 30kg / mu, potassium nitrate 8kg / mu, magnesium sulfate 15kg / mu, agricultural borax 5kg / mu, 80g / mu mixed with water, stirred thoroughly and mixed evenly. After the fertilizer is completely dissolved, sprinkle it evenly in the soil around the root of the black sugarcane. In addition, 0.1% magnesium sulfate, 0.1% borax, 0.3% potassium nitrate and 600 times amino acid compound micronutrient mixture should be sprayed on the leaf surface for 3 times, and once every 7 to 10 days, all stems and leaves should be evenly sprayed, so that it is appropriate to start dripping water droplets, which is beneficial to increase the yield.
