In winter, the soil moisture will be flat or low, and the width of soil moisture is 2.5-3 m; In autumn, it should be cut into small and high soil moisture, with a soil moisture width of 0.8- 1m and a ditch depth of 20-30cm. 2. Carry out the first thinning when there are 2-3 true leaves, the second thinning when there are 4-5 true leaves, and the seedlings will be fixed when there are 5-6 true leaves. Seedling spacing is 20-24cm in autumn and15-18cm in winter. 3. When the cross is pulled out, the first fertilizer is applied, and 5 kilograms of calcium superphosphate, 5 kilograms of ammonium bicarbonate and 500 kilograms of seedlings per mu are added to the water; After emergence, 5 kg of urea and 5 kg of potassium sulfate are added to 500 kg of water for topdressing, and then topdressing is performed once every 10- 15 days, with urea 15-20 kg per mu. Topdressing should be combined with irrigation to keep the soil moist. 4. Harvest: The harvest time of green vegetables depends on variety characteristics, cultivation season and market demand.
