Three points of attention should be paid to the fertilization of Chinese cabbage:
First, the application of nitrogen fertilizer should be appropriate, because most of the soil nitrogen content exceeds the standard in most areas, which not only causes poor cabbage, but also leaves water, and it is not easy to store after harvesting, so the fellows should master the cabbage seedlings. The nitrogen supply accounts for about 2% of the total fertilizer, the rosette period accounts for about 28%, and the core period accounts for about 70%.
The second is to increase the proportion of phosphorus and potassium fertilizer application. Generally, 12 kg of potassium chloride or 16 kg of potassium sulfide should be applied per mu of land. The application method should be applied to the bottom of the hole at the time of planting, and it can be poured in the continuous period.
Third, when applying base fertilizer, calcium phosphate should be added to supplement the nutrition of calcium in Chinese cabbage, which can prevent Chinese cabbage from burning heart disease.
