Fertilization technology of Chinese cabbage

The cabbage topdressing is mainly based on nitrogen fertilizer, but at the same time of the application of nitrogen fertilizer, it is necessary to increase the application of phosphorus and potassium fertilizer. Two fertilizations before the cabbage enters the rosette and the core are the key to high yield. If the nitrogen fertilizer is insufficient during the growth period, the plant is short and the tissue is rough. If the phosphorus and potassium fertilizers are insufficient in the late stage of cabbage, it is often difficult to form a ball.
