In order to cultivate Chinese cabbage in summer with mobile seedbed, first prepare the seedbed. 15 days before sowing, prepare the original soil with fertile land and convenient drainage and irrigation, then deep plough and expose the seedbed soil. 5 kg of rotten organic fertilizer and 100-200g of plant ash shall be applied in combination with the seedbed of the square meter of land preparation, which shall be fully mixed, the border surface shall be leveled and raked after watering.

　　Water enough before sowing, water the nutrient solution filled with soil in the moving seedbed for 2 times, and then sprinkle the seeds into the seedbed evenly after the water basically seeps through, covering with fine soil 1 cm thick. The seeding rate per square meter of seedbed is 2-3g, and the seedbed is required for each mu of cultivated land

　　30-50 square meters, 100-150 grams of seeds are needed. After sowing, water should be poured once, with small amount of water.

　　At present, in order to ensure that the seedlings are full and strong, most planters adopt the method of seedling and transplanting.

　　When the seedlings are unearthed, they can be ready for transplanting when they grow to 4-5 leaves. One day before transplanting seedlings, the seedbed should be watered, and transplanting should be carried out after 4pm in cloudy or sunny days. When the seedlings are raised, they should be transplanted with soil and handled with care to prevent the soil cube from scattering and damaging the root system.

　　Before planting, 2000 kg of high-quality farmyard fertilizer and 20 kg of ternary compound fertilizer were applied per mu of land preparation. The width of the furrow is 1.2m, two rows are planted in each furrow, the plant spacing is kept at 25-30cm, the width of the furrow is 1.5m, three rows are planted in each furrow, and the plant spacing is 30cm.

　　After transplanting, compact the seedlings around with fine soil, and then water the roots.

　　The characteristics of using mobile seedbed to cultivate cabbage are that it can be moved, increase the effective use area of greenhouse, effectively reduce pests and diseases, shorten the plant production cycle, save seed consumption, reduce energy consumption, and appropriate mechanized operation.
