The phenomenon of early convulsions often occurs in cabbages planted in early spring, which will directly affect the quality and yield of cabbage, and even cause severe production, which will cause great losses in production. How can we prevent precocious Spring Cabbage convulsions? Use suitable high quality varieties. Precocious spring cabbage cultivation should use strong winter varieties, such as the Tianzhengdong Cabbage cultivated by the vegetables of Shandong Academy of Agricultural Sciences, and 8398 cultivated by the Chinese Academy of Agricultural Sciences, all suitable for early spring ripening. Timely sowing, control seedbed temperature. The suitable sowing date for the cultivation of 8398 in North China is from late December to early January. Cold bed breeding is also available, and it can also be planted in the greenhouse or modified Yangshuo in mid-January. When the seedlings are out of alignment, they should pay attention to air release. The seedbed temperature should not exceed 15°C. Strengthen the control of temperature, moisture and light to prevent leggy growth. The first time the seedlings were planted in mid-February and planted in mid-March. Strengthen field management. Pay attention to the appropriate early seedlings, in order to promote spring cabbage early maturing and high yield, after the spring cabbage planting seedlings, do not make the seedlings grow too prone during the early period, two measures should be taken to shoot the seedlings, that is, after the seedlings cultivating, 7 days watering once, and then cultivating . After 7 days or so, fertilization and watering were started. The plants were planted in small plastic sheds and covered with mulch in early spring cabbage. After pouring enough water for planting, they were generally not watered. Shed temperature is generally controlled below 25°C. After 20 to 25 days from the time of colonization, the membrane was gradually withdrawn, and the shed film was completely removed within 5 to 10 days in order to control the outer leaves and promote early maturation. When you start to care about your heart, pay attention to top dressing and watering.
