Spring cabbage seedlings
Spring cabbage has the characteristics of less investment, labor saving and high output in production. Growing cabbage in the spring can be very economical. Right now, the spring cabbage breeding season again, below, introduce the relevant technical points.
Choose a variety. Early spring cold shed cultivation can use strong cold resistance, strong disease resistance, strong winter varieties, such as select 8398, spring strong and other varieties. Planting in the open field in the spring can use Zhonggan 15, Zhonggan 21 and other early maturing, high-yield and disease-resistant varieties.
Prepare a seedbed. Nursery bed soil to choose fertile soil, last year did not grow cruciferous vegetables in the pastoral soil, to give full maturity of the farmyard fertilizer 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.
Seed management. Before emergence, the greenhouse or Yangshuo temperature 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, if the seedlings too dense, You need to conduct the seedlings to prevent the seedlings from becoming leggy. When the seedlings grow to three true leaves, a sub-seedling will be carried out and the seedlings will be transplanted into the nutrient bowl. The temperature of the seedbed is generally controlled at 8°C to 20°C, and the low temperature can be achieved before the seedlings are planted in March. In order to increase the air flow, the minimum temperature of the seedbed can be gradually reduced to about 5°C, and the time for hardening the seedlings is about one week. Afterwards, they are planted according to their cultivation mode and weather conditions.
