Last Updated: 2024/11/05, First, the characteristics of sugarcane fertilizer requirement. As far as a large number of elements are concerned, the fertilizer requirement of sugarcane is that the absorption of potassium is greater than that of nitrogen, and that of nitrogen is greater than that of phosphorus. Among them, nitrogen fertilizer should be applied less in the early stage, re-applied in the growing period, and applied appropriately in the later stage. Due to the concentration of phosphate fertilizer in the early growth stage of sugarcane, it has a great influence on the growth of hairy root and seedling, so it is suitable to be used as base fertilizer.

In recent years, with the continuous adjustment of agricultural planting structure, the mode of sugarcane rotation has also changed. The main models can be divided into two types: paddy field and dry land. Flood-drought rotation model: spring planting sugarcane-ratoon sugarcane-rice; spring planting sugarcane-spring planting sugarcane-rice; spring planting sugarcane-cotton (18685115.00 0.62%) (vegetable)-rice. Dry land rotation model: spring planting sugarcane-ratoon sugarcane-cotton; spring planting sugarcane-spring planting sugarcane-cotton; spring planting sugarcane-persistent root sugarcane-vegetables: spring planting sugarcane-Ramie-cotton; spring planting sugarcane-spring and summer vegetables, winter rape-cotton.
