Spring cabbage planting time and method cultivation technology and management points

Spring cabbage planting time

Spring cabbage can be sown and raised from December to mid-January, mostly in a greenhouse. The time for raising seedlings is not fixed. The sowing time can be adjusted according to the local climate, and a sunny morning can be chosen for transplanting.

How to Plant Spring Cabbage

1. Sowing method

Spring cabbage is sown using the dry seed direct seeding method. The seeds must be sown evenly and the seedbed must be thoroughly disinfected before sowing. Fertile soil is required for planting cabbage. Fully decomposed farmyard manure can be applied during farming, and a ternary compound fertilizer of nitrogen, phosphorus and potassium can be mixed in proportion.

2. Greenhouse conditions

The film cloth does not need to be removed in winter in the greenhouse where cabbage is planted in early spring, because the permafrost layer is shallow and the soil temperature rises quickly in early spring. The greenhouse floor should be cleaned before sowing, and a second layer of film cloth should be applied. The film cloth should be pulled down during the day to increase light, and the temperature should be pulled up at night when it is lower.

3. Field management

After the cabbage is planted, attention should be paid to field management. Quick-acting nitrogen fertilizer should be applied in time. Compound fertilizer should be applied when the cabbage is in the heart. After the early spring mulch cultivation and the seedlings have been set, the temperature in spring is relatively low, so the amount of watering should be reduced. Flooding should not be carried out with large amounts of water. Drain water in time after rain to avoid waterlogging.

Precautions for planting spring cabbage

Spring cabbage has few diseases and pests, mainly aphids and cabbage loopers. Aphids can be controlled by spraying aphidicide emulsifiable concentrate, usually once every 6-7 days, for 2-3 times in a row. Cabbage loopers can be controlled by spraying pyrethroid emulsifiable concentrate.
