As overwintering delayed cabbage, generally choose seven grass, spring color and other varieties. Second, raising seedlings: autumn and winter cabbages are raised in sunshade or semi-protected areas, generally sowing in batches from late June to late July. The sowing time for overwintering harvest is usually from late July to mid-August. Autumn and winter cabbage is sown in summer. Because of the high temperature, the seedlings must be carefully managed. Sunshade net is used to cover the soil after sowing to maintain soil moisture and prevent soil hardening after heavy rain. Remove the sunshade net after emergence and change to a ring shed in time. About 15 days after emergence, when the seedlings have 3 Mel 4 true leaves, the seedlings should be transferred (pseudo-planting) with a distance of 10 cm square. After transplanting seedlings 3MUE live for 4 days, they can be fertilized once. Third, soil preparation: the soil preparation of autumn cabbage is the same as that of summer cabbage, while the soil preparation of overwintering delayed cabbage is the same as that of spring cabbage. 4. Planting: autumn and winter cabbage seedlings have a seedling stage of 35ml for 45 days, so if they are sown from late June to late July, the planting period is generally from early August to early September. The planting period of overwintering cabbage is generally from late September to early October, and no later than October 15 at the latest. Autumn cabbage planting temperature is still high, it is best to choose cloudy days; and seedlings should carry soil to reduce root damage; immediately after planting, root water should be irrigated to promote living plants. Planting density: varieties of large flat head type, with row spacing of 50 cm and plant spacing of 40 cm, about 2800 plants per 667m 2; varieties of black leaf and small flat head type, with row spacing of 43 cm and plant spacing of 40 cm; April slow cabbage, with a row spacing of 40 cm, 3500Cal 4000 plants per 667m 2. Fifth, field management: strengthen fertilizer and water management, promote early heart. Autumn cabbage is generally topdressing for 3 times, applying urea 10kg per 667 square meters one week after planting live plants, and 10ml 20kg urea per 667 square meters in the early and later stages of heading. Overwintering cabbage should not be too tight before overwintering. Therefore, the amount of topdressing in the early stage of heading should not be too much, applying 10 kg of urea per 667 square meters. In this way, the leaves are not easy to be damaged by freezing in winter, and the leaf balls are not easy to rot in order to postpone the harvest. The Beginning of Spring was re-applied pericardium fertilizer every 667m2, 20ml 30kg urea. Autumn and winter cabbage are mainly pests, mainly cabbage worm, Plutella xylostella, beet armyworm, Spodoptera litura and so on. Harvest: autumn and winter cabbages are generally harvested from mid to late October and can be harvested from January to February of the second year; April slow cabbages are harvested from mid-March to mid-April.
