After the entire underground species is planted, the surface of the soil is sprayed with 600-800 times liquid of new high-fat film. The water can be protected against evaporation, sun protection, drought resistance, thermal insulation and frost protection, and soil protection. Shears, suffocates and isolates pests and sources of disease to increase seedlings. 2. Seedling management: timely release after emergence, take a small arch shed to cover the shade net to prevent direct sunlight. To grow to 2-3 true leaf seedlings once, will grow too dense to pull out, keep a certain interval.

Third, field management: During the growth of the autumn cabbage, often encounter high temperature and dry weather or showers, so long time the rain should not be timely watering, the use of manure water every 5-7 days to chase once, first light after the thick. During the rosette period, strong stems and vegetables are sprayed to make the stems thick, leaves hypertrophy, leaves fresh, plant lush, and natural taste.
