What should we pay attention to when leaving black sugarcane for the winter? Please instruct the black-skinned sugarcane to re-apply potash fertilizer in winter in order to improve the nutrition level of the plant and the potassium content of the remaining seed part. Only in this way can we enhance the cold resistance and winter resistance of sugarcane species, make the sugarcane buds full, sprout early, germinate quickly, sprout neatly, have strong seedlings, strong disease resistance, fast growth speed, and easily obtain high yield and excellent quality after next spring. Specific methods: in winter, apply potassium fertilizer to the root of black-skinned sugarcane once, generally, apply 60 kg of potassium nitrate or potassium sulfate per mu, 100 times the amount of water for 80 times, and then evenly apply it to the soil around the root of black-skinned sugarcane. At the same time, 0.3% 0.5% potassium dihydrogen phosphate aqueous solution, or 300ml 500 times potassium nitrate aqueous solution, is sprayed on the leaves every 15 days, and 3 Mel is sprayed 5 times in a row to wet all stems and leaves evenly, so that it is appropriate to start dripping water. This method can obviously increase the potassium content of black-skinned sugarcane plants, make the sugarcane species stout, the bud eyes full, and obviously improve the quality of sugarcane seeds.
