Sugarcane Paddy-Upland Rotation Planting Model and Key Technical Points
I. Fertilizer Requirements of Sugarcane. In terms of macronutrients, the fertilizer requirements of sugarcane are characterized by potassium uptake exceeding nitrogen, and nitrogen exceeding phosphorus. Nitrogen fertilizer should be applied lightly in the early stage, heavily during the growing period, and moderately as a top dressing in the late stage. Since sugarcane has a relatively concentrated demand for phosphorus fertilizer in the early growth stage, which greatly affects root development and seedling growth, it is advisable to apply it as a base fertilizer...
In recent years, with the continuous adjustment of agricultural planting structures, sugarcane rotation patterns have also changed. The main patterns can be divided into two major categories: paddy field and upland field rotation patterns.Paddy-upland rotation patterns: spring-planted sugarcane - ratoon sugarcane - rice; spring-planted sugarcane - spring-planted sugarcane - rice; spring-planted sugarcane - cotton (18685,115.00,0.62%) (vegetables) - rice.
Upland rotation patterns: spring-planted sugarcane - ratoon sugarcane - cotton; spring-planted sugarcane - spring-planted sugarcane - cotton; spring-planted sugarcane - ratoon sugarcane - vegetables: spring-planted sugarcane - ramie - cotton; spring-planted sugarcane - spring and summer vegetables, winter rapeseed - cotton.
