The farmer said that "autumn is early, cold is late, and autumn is planted at the time". If the planting is too early, the seedlings are too strong when wintering, and the cold resistance is weak; if the seeding is too late, the seedlings are too small, which is not conducive to the safe wintering of the seedlings, and the yield is low. It is necessary to fertilize the land in advance, and apply 3,000 kilograms of decomposed and finely divided high-quality organic fertilizer or more than 2,000 kilograms of commercial organic fertilizer per acre.

Each time, 10 kg of nitrous phosphorus-containing ternary liquid fertilizer is applied per acre with water, and cabbage is stopped for 20 days before harvesting. Foliar spray once every 7 days or so, with the effect of functional fertilizer such as Lei Li 2000, to quickly supplement nutrition and promote growth. Do a good job in controlling pests such as downy mildew, soft rot, cabbage caterpillar, and aphids.
