How to manage greenhouse vegetables in winter snow days

1, normal lifting quilts

First of all, in addition to the normal lifting of the quilt at this time, it is best to put a layer of two-layer film on the quilt. In addition to the effect of heat preservation, this film can also protect the quilt from being snow-immersed in the snow. Wet, due to the smoothness of this film, it is easier to sweep snow when it is snowed.

Secondly, the control of wetness in the shed has always been the work we have to do. At this time, we must do a good job. If you are pouring the ground, do not pour the water. Try to spray less medicine. You can use the smoke agent to smoke the shed. Because it is possible to open the tuyere for several days when it snows, it is more likely that the quilt will not be opened. If the humidity in the shed is high, it will be more likely to cause disease.

When it is snowing, when the snow is not very big, try to put the top wind for about one hour every day at noon. If you do not open the air in the greenhouse for a long time, you will accumulate a lot of harmful gases mainly composed of carbon dioxide. You can release the harmful gases after one or two hours of release. .

This problem has different opinions about growing vegetables in different places. Some people think that it is better to raise the quilt because a thick layer of snow is covered on the shed film, which can play a good role in keeping warm, even if the snow covers the shed. There will be a little light. If the quilt is put down when it snows, and it will take a few days under the snow to uncover the quilt, then the dish in the shed will be smashed. It is not a good thing. Then the snow immersed quilt will become very Heavy, it is possible to collapse the shed.

2, after the snow days, clear management

It is necessary to clean the shed under the shed in time, but now there are more old people who grow large sheds, so be careful when sweeping the snow. If the snow is not too big, don’t sweep it, wait until the snow stops and then slowly Clean up.

When the snowy weather passes, the weather is fine, you can rest assured, no, this time the greenhouse management is the key, because once it is clear, the temperature in the greenhouse will rise very quickly, the evaporation of vegetables is large, the water loss is more, and the ground temperature Without going up, the activities of the root system are still very weak, and the vegetables will be wilted due to excessive water loss. If they are not taken in time, they will develop into long-term wilting and eventually die. Therefore, after the snowy weather, it is necessary to pay attention to observation. Once the leaves are found to be wilting, the quilts should be put down, and the leaves should be uncovered after repeated recovery. So repeatedly, the vegetables can adapt to the light and the ground temperature rises.
