At present, the agricultural season has passed the cold dew, coupled with the rain and snow weather, many places have begun to have a strong wind and cool down, today I will share with you the autumn low temperature frost, freeze damage prevention measures.
Autumn low temperature frost, freeze damage prevention measures:
1. For large-area open vegetables such as: doll dish, Chinese cabbage, cabbage, celery, radish and other vegetables with low temperature resistance, water can be poured in time before cooling to keep the soil moist, which can effectively reduce the freezing damage.
2. Fruits and vegetables such as bananas, cucumbers, eggplants, and peppers that are poorly cultivated in the open field should be harvested in time, and the mature fruits should be harvested in time. For small-scale fields where the growth of the plants is still good and the fruits are not yet fully mature, It can be covered with shed film, straw, etc. before the frost comes, and the cover is removed after the temperature rises during the day. After the fruit is ripe, harvest, pull and clean the garden in time.
3. For vegetables that use the plastic arch shed for late-delay cultivation, the shed should be covered early before the cold current to prevent frost and freezing damage.
4. The greenhouse in which the vegetables are grown should be sorted and covered with the shed film before the cold current arrives. The bottom corner of the shed film should be buried and compacted. The vents should be closed in time to prevent cold and heat preservation. At the same time, the straw curtain or insulation should be prepared and placed. In place, in case of a strong cooling, cover the curtain at night.
5. In case of strong cooling, the nursery greenhouse can be covered with a small arch shed in the greenhouse, or it can be used for short-term use of electric stove, Yuba lamp, incandescent lamp, etc. to ensure the seedlings are not harmed. But be sure to pay attention to electricity safety and prevent fire.
