Strengthen water-centred cultivation management. Apply basic fertilizer, apply balanced fertilization to avoid partial application of nitrogen fertilizer; low-humid fields should be cultivated with high hoe, and rainy areas should pay attention to drainage of drains; clean pastoral after harvest. 4.
