Severe weather how to manage the greenhouse vegetables
The disastrous weather in the winter production of solar greenhouse vegetables mainly includes: strong wind, persistent cloudy snow, cold current cooling, continuous low-temperature illumination, and long-lived sunny weather. In case of severe weather, measures should be taken in time to ensure that the plants safely pass through the winter. When the windy weather encounters windy weather during the day, the film should be pressed immediately or a part of the grass should be put down and pressed in the middle of the roof in front of the greenhouse. The arc of the roof in front of the greenhouse is small, and the laminating line pressure is not firm. It is best to use a bamboo raft for lamination. When the wind is blown away at night, it should be pulled back to its original position in time. It is best to cover the grasshoppers at the bottom of the greenhouse and press them firmly with stones. Even the cloudy days encountered continuous shade weather, and on the basis of heat preservation, more light was needed. Should use scattered light of cloudy day as far as possible, as long as the temperature does not drop after uncovering the grasshopper, it must be revealed. Even if the outside temperature is low and the temperature drops after uncovering the grasshoppers, we must also uncover the grasshoppers before and after noon, let the plants see the scattered light of half an hour to one hour, or remove the back cover to ensure that the plants see light every day. . If the duration of long-lived or extremely cold temperatures is long and the room temperature continues to drop, it is necessary to supplement the heat before the temperature falls until the growth is about to be affected, and the temperature is raised to 13°C to 15°C to ensure that the plants are not affected by cold. When the cold current is strong and the temperature is lowered, the cold temperature and strong temperature-reducing weather are encountered. According to the heat preservation of the greenhouse and the difference of the cultivated crops, the small shed is temporarily buckled, and the paper back, non-woven fabric, whole old plastic sheet, and haystack are added to the awning. Temporarily assist with warming, taking care not to leak smoke into the room. Auxiliary heating as long as the crop is free from frost damage, must not be too high indoor temperature, so as not to affect the normal development. When the snowfall temperature is not very low, in order to prevent the grasshoppers from getting soaked, they can be rolled up and stopped after the snow stops. In the case of snowfall and cooling at the same time, it is not appropriate to roll grass weeds. When snowstorms occur, you should scrape the snow with a snowboard to prevent the snow from getting too thick. Especially when a snowstorm is encountered at night, the snow should be removed in time. After a long period of overcast days, sunny and sunny days are often fine. After uncovering haystacks, the imbalance of plant water will lead to wilting. If the growth points are damaged, the whole shed vegetables will be killed. At this time, measures must be taken to look back. The method is to let the sun shine after the day is clear so that it can be seen in the early morning sunshine. If the plants are found to be wilting, they should be covered in time, or they can be sprayed with leaf spray to adjust the water balance.
