Detailed Explanation of Chinese Cabbage Planting Techniques and Field Management Methods

1. Reasonable fertilization. During the head-forming stage of Chinese cabbage, increase the application of phosphate fertilizer, potassium fertilizer and organic fertilizer, and control the amount of nitrogen fertilizer to suppress excessive plant growth. Generally, at the early heading stage and the mid-heading stage, apply monopotassium phosphate as a top dressing once each.

2. Scientific water supply. During the head-forming stage of Chinese cabbage, the water supply should be uniform and sufficient, and it is important to avoid alternating between too much and too little. Every morning and evening, also pour 1 application of clean water over the plants, using 1-1.5 kg of clean water per plant each time.

3. Pest and disease control. When pests and diseases occur during the head-forming stage of Chinese cabbage, continuously spray 2-3 times a mixed solution of 1500-fold Nongdile, 2500-fold Qingjunazole and Xin Gaozhi film.

4. Foliar top dressing. When controlling pests and diseases in Chinese cabbage, 1000-fold foliar fertilizers such as Luye Xianfeng can be added to the sprayed liquid and applied together. Foliar top dressing can make the cabbage heads firm and compact.
