Vegetables in the greenhouse to prevent cold and warm measures
1, before the advent of cold air, we must do a good job of keeping warm crops. Now, there are more high-crop crops in the shed, such as tomatoes and cucumbers. High-crop crops cannot be covered with small sheds, nor can they be covered with foliage. It is therefore recommended that preparations for the second-tier membrane should be made before cold air arrives.
2. For the lettuces and other vegetables currently in the shed, a layer of insulation facilities is not safe enough, because they each have the temperature requirements, such as eggplant vegetables no longer grow below 15 °C; leaf vegetables include Lettuce, lettuce, etc., stop growing below 5°C, and it may even be frozen when the temperature reaches zero. Therefore, for these vegetables, warm work can be performed according to the conditions of their own facilities, such as adding a small shed and increasing the cover.
3, sometimes it rains and snow, the temperature is below zero, the vegetables in the shed are not easy to be frozen, but in the weather after the rain is clear or sunny after the snow is very prone to frost damage. Because the frost is particularly large after the first clear weather, the weather needs special attention. It is recommended to increase the cover during the first clear days.
