Spring Cabbage Winter Seedling Four Points

Choose the best kind of cold shed cultivation in early spring can choose strong cold resistance, strong disease resistance, strong winter varieties, spring open field planting can choose early maturing, high yield, strong disease resistance varieties.

Prepare seedbed nursery bed soil to choose fertile soil. In the past year, there was no pastoral soil for cruciferous vegetables. Full maturity farmyard manure should be applied to match the amount of ternary compound fertilizer. Before sowing, 50% of methine WP can be used to completely sterilize the seedbed, and the dosage per square meter is about 10 grams.

The appropriate sowing date for the timely sowing of spring cabbage is from late December to mid-January, and the use of solar greenhouse nursery or improvement of Yangshuo nursery. For early maturing varieties, the average planting density is 4,500 to 5,000 for acre and 3,500 to 4,000 for middle-maturing varieties. It is advisable to use about 50 grams per mu. Before sowing, the seeds generally do not need to be germinated and the seeds can be broadcast live.

Seedling management before emergence, the temperature of the greenhouse or Yangshuo to maintain 15 °C - 25 °C, generally 5 days after sowing can be Qimiao, this time, pay attention to timely and gradually release the air, so that the temperature is maintained at 10 °C - 20 °C. When the seedlings grow to three true leaves (mid-mid-February), a sub-seedling will be conducted. The temperature of the seedbed is generally controlled at 8°C to 20°C, and the temperature will be low before the seedlings are planted in March. ". Afterwards, they are planted according to their cultivation mode and weather conditions.
