During winter pepper breeding, it is often attacked by a sudden cold current, the temperature suddenly decreases, and the seedlings are vulnerable to freezing. If the temperature is slowly reduced, it is not easy to freeze and freeze. If the temperature is not too low, but the low temperature duration is very long, especially in the case of low temperature and rainy weather that is accompanied by "wet and cold", the seedlings are also prone to frost damage. The severity of frost damage in seedlings is also related to the speed at which the temperature rises after low temperatures. If the temperature rises slowly, the thawing of the seedlings is also slow and it is easy to restore vitality. If the temperature is increased and the thawing is too fast, the tissue of the seedlings will be prone to dehydration and dryness, resulting in dead seedlings. Effective antifreeze methods have the following aspects: 1. Improve the method of raising seedlings: The use of artificial temperature-controlled seedling raising methods, such as electrothermal hotbeds and industrialized seedlings, is the fundamental measure to thoroughly solve the freezing problem of seedlings. 2, to enhance the cold resistance of seedlings: to avoid seedlings leggy, before the advent of low-temperature cold, try to remove the cover, so that seedlings shine and receive training. During continuous rain, frost, and low temperatures, we must also remove the straw as much as possible. At least 1-2 hours a day, let the seedlings shine into the sun. After the rain suddenly stopped turning, it is necessary to cover a few grass curtains on the seed bed before and after noon to avoid water loss and wilting of seedlings. If the humidity in the bed is large, the seedlings are vulnerable to freezing. Therefore, the seedbed watering should be controlled before the cold wave arrives. There is a layer of hay ash that is too wet in the bed. 3, rational fertilization: increase phosphorus and potassium fertilizers, seedlings use cold resistance. Seedlings spray 0.5%-1% brown sugar or glucose water, can enhance the cold resistance. Applying 0.5% calcium chloride twice at intervals of 7 days (7 days apart) will increase cold resistance. 4. Insulation and freezing: During the cold wave, the seedbed should be closely covered. 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. Some of the outer layers of rice straw are sprinkled on bed seedlings and cleared after the cold wave. The straw curtain on the seedbed should be dry. After frost stops on the next frost day, the cream will be cleared out of the nursery site in time.
