In late December, heavy snowstorms in northern Xinjiang have brought a lot of troubles to greenhouse growers. For example, in Tacheng, Xinjiang, thick snow covers the greenhouses. If the greenhouses cannot support them, they will collapse immediately. Thick snow will also block the sunlight. The growth of vegetables without sunlight will be seriously affected, so the local farmers have been working very hard to clean the snow on the greenhouse.
Due to the persistence of snowfall, Altay's snowfall increased by 4 to 5 centimeters this morning, while Tacheng reached a depth of 10 centimeters.
Another place where the snow is deep is the Heilongjiang River in the northeast. The recent snowfall is not only a long time, but also the intensity is not small. It is expected that the main snowfall in the country will be concentrated in the northeast of Inner Mongolia, Heilongjiang, and the northern part of Xinjiang in the next two days. In this way, the depth of snow in northern Xinjiang is expected to be 40 to 70 centimeters, and the depth of snow in the northeast of Heilongjiang will reach 30 to 60 centimeters. Therefore, it is especially reminded that the facilities agriculture must be prepared for snow prevention.
It is expected that the temperature in Xinjiang and Northeast China will not drop significantly in the next two days, and some areas will increase, but it is still cold in the cold. For example, the highest temperature in Northeast China may be less than minus 10 °C, and the northern part of Xinjiang may be less than minus 5 °C. The temperature is not conducive to the melting of snow, so the cleanup of snow in greenhouses in the past two days is still grim.
The following are some knowledge of agricultural snow disaster relief facilities:
one. It is to repair the greenhouse in time, remove the snow immediately, and fix the time to repair the greenhouse and the greenhouse frame and the shed film. The pillars in the room should be reinforced, the cracks in the wall should be repaired, the deformed skeleton or the broken skeleton should be repaired, and the laminating line should be strengthened. The film around the shed should be pressed with mud, and the film should be filled with tape to reduce the cold air at the bottom.
two. It is heat preservation and warming. Temporary warming measures were taken to properly regulate the temperature inside the shed. Such as coal stoves, heating, temporary combustibles, etc., even with candles to have an effect. But pay attention to fire and electricity, pay attention to safety. It is also possible to adopt a small shed in the shed and to increase the temperature by adding a film at night. Fruits and vegetables generally have a temperature of 8-10 ° C, and leaf vegetables generally have a temperature of 10-13 ° C.
three. It is to improve the lighting conditions in the shed. It is necessary to expose the curtains as early as possible, and the form of the uncovered curtains is taken at the beginning of the curtain to prevent acute wilting caused by direct sunlight.
four. It is the treatment of freezing damage. After the freeze damage of greenhouse vegetables, the following measures can be taken to reduce the hazard. First, irrigation and heat preservation should be carried out to restore the frozen tissue. Second, let the wind cool down, so that the temperature in the shed slowly rises, avoiding the rapid rise of temperature, causing the plant to grow slowly, and the new leaves are delayed. Third, it is necessary to apply foliar fertilizer reasonably, and it can be sprayed with exogenous plant hormones to promote growth and speed up the recovery of the body. For crops and seedlings that have been frozen, it is forbidden to use hormone-promoting drugs that promote growth. It is recommended to use 300 times liquid rice vinegar spray leaves (50 ml to 15 kg water). It is also recommended to add 30 g of potassium dihydrogen phosphate. Resistant, especially for cucumbers, tomatoes, etc., with a lighter leaf color, spray 75 grams of urea.
Fives. It is the wintering vegetables in the open field, such as wintering spinach and onions, etc. It is necessary to remove the snow in the field in time to prevent the vegetable roots from suffocating and dying.
