1. Sugarcane is a C4 crop with strong photosynthesis and high yield performance. It also has high requirements for water and fertilizer conditions. Producing 1 ton of sugarcane requires 2 kilograms of pure nitrogen, 1.5 kilograms of pure phosphorus, and 2.5 kilograms of pure potassium. Among the fertilizer requirements during the entire growth period, the seedling stage only accounts for about 1%, the tillering stage accounts for about 10%, the elongation stage accounts for more than 50%, and the mature stage accounts for 20~40%. Therefore, the fertilizer should be applied according to the principle of "apply base fertilizer enough, apply seedling fertilizer early, Fertilize according to the principle of "apply tiller fertilizer steadily, apply stem fertilizer heavily, and apply tail fertilizer as appropriate". Sugarcane loves potassium. Appropriate application of potash fertilizer can increase yield and improve product quality.

2. Apply sufficient base fertilizer: generally apply 1,500 kilograms of farmyard manure per mu, combined with 30-50 kilograms of compound fertilizer (the specific amount of fertilizer can be adjusted appropriately according to soil conditions).

3. When planting cane in spring, open a planting ditch, apply organic fertilizer to the bottom of the ditch, and then apply inorganic fertilizer on both sides of the ditch; when planting cane in winter, use organic fertilizer as a cover seed fertilizer and cover it with soil in time. Create conditions for rapid growth of sugarcane buds, elongation of roots, and early and strong tillering.
