1. Before the application of basal fertilizer, after the crop is harvested, apply 3,000 to 4,000 kilograms of loop fertilizer per 667 square meters as a base fertilizer, deep-turn, and leveling to make a ridge with a width of 60-66 cm and a height of 15-18 cm. If the organic fertilizer is not enough, after the land is turned upside down, apply rot 1000 to 2,000 kg per 667 square meters of row spacing, and then replenish the ridge to implement centralized fertilization, which can better exert the fertilizer effect.
2. The application of topdressing fertilizer to cabbage has the characteristics of resistance to fertilizer, resistance to pods, and strong absorptive capacity, but in order to produce high yields, it is necessary to strengthen fertilizer and water management. In the vegetative growth stage of rutabaga, approximately two topdressings can be carried out, and the first topdressing after live seedling or survival after transplanting is performed, and 15 to 20 kg of ammonium sulfate per 667 square meters or 50 to 750 kg of human waste is applied. The second top-dressing during the peak period of fleshy root enlargement applied 25 to 30 kg of nitrogen, phosphorus and potassium compound fertilizer per 667 square meters, and 100 to 150 kg of plant ash. 750 kg of human waste.
