How to manage vegetables in greenhouse in wet and cold weather.

It is suggested to cover the vegetables in the open air with black plastic film to prevent the cold and humid air from forming the first frost at night, which will lead to the freezing of vegetables. If it's a greenhouse vegetable, in wet and cold weather, we can warm the room through air conditioning to achieve the purpose of cold protection.

It is very difficult to manage plants and vegetables outdoors in wet and cold weather. Because any first frost at this time may cause the vegetables in the whole field to freeze and rot, it is necessary to do a good job of antifreeze for vegetables in time at this time. Recently, the weather in southern China has been below zero, so many vegetable farmers may face losses in Chinese cabbage, lettuce and other onions and garlic. If you don't do a good job in cold protection, the loss will be quite serious.

In wet and cold weather, we shouldn't water the vegetables any more. Because watering at this time is easy to freeze the ground, leading to vegetable root rot. Vegetables go bad easily if they are not picked in time.
