To prevent the freezing of pepper seedlings
Antifreeze measures for pepper seedlings are as follows: 1. Improve seedling methods. The use of artificial temperature-controlled seedling raising methods, such as electric hotbeds and industrialized seedlings, is the fundamental measure to solve the freezing problem of seedlings. 2, enhance seedling cold resistance. Avoid seedlings and leggy pigs. Remove the cover as much as possible before the onset of the cold spell to allow the seedlings to shine and exercise. During the cold period of rain and snow, try to use the weather to clear the gap, remove the grass curtain, and let the pepper seedlings shine into the sun. When the rain and snow stopped suddenly, it was clear before and after noon that a few grass curtains were placed on the seedbeds to prevent the seedlings from dehydration and wilting. Bed soil moisture is high, seedlings susceptible to frost damage, so control the seedbed watering before the onset of the cold wave, bed soil too wet to sprinkle a layer of hay wood ash moisture. 3ã€Appropriate increase in fertilization, application of phosphorus and potash fertilizers, and use of cold-resistance agents at the seedling stage. Seedlings sprayed with 0.5% to 1% brown sugar or glucose water can enhance cold resistance. Spraying 2 times (with 7 days interval) 0.5% calcium chloride solution in the 3 to 4 leaf stage can enhance cold resistance. 4, thermal insulation. During the cold wave, the bed was covered closely. When ventilation is performed for a short period of time, cold air must be prevented from directly blowing into the bed. Cover straw at night. The straw leaves can be sprinkled on the seedlings and cleared after the cold wave. The straw curtain on the seedbed should be dry. After the snow stopped in the snow, the snow was cleared out of the nursery.
