How to rationally fertilize cabbage

Cabbage is a cabbage, also known as cabbage, kohlrabi. When applying farmyard manure as base fertilizer on the ground of planting cabbage, 225-300 kg of superphosphate should be applied. When cabbage enters the rosette stage, the plant must form a strong assimilated organ, which is the most critical period for absorbing fertilizer and water. At this time, topdressing should be carried out. When applying nitrogen fertilizer such as ammonium bicarbonate, the early maturing varieties are applied 15-20 kg per mu, and the medium and late maturity varieties are applied 10-15 kg per mu. Watering after topdressing. As the temperature increases, the cabbage enters a period of vigorous growth, and the early-maturing varieties begin to wrap up quickly, eliminating the need for topdressing. Medium and late-maturing varieties, when the plant begins to wrap, apply 15-20 kg of nitrogen fertilizer per mu, and timely fill the water after topdressing to promote leaf growth.
