Recently, Henan, Shandong, Hebei, Anhui and other regions have experienced a wide range of persistent rain and snow weather. Although this weather can alleviate the drought of crops, the chilling and freezing damage that comes with it cannot be underestimated. After that, how should crops prevent freezing and damage? First, the field crop The field crops in the northern region are generally dominated by winter wheat. Wheat begins to slowly return to the greening stage after the year. Although winter wheat has a certain ability to resist cold, the cold and frost resistance of wheat when it enters the greening period will be relatively weak, and heavy snow will appear. Afterwards, it is recommended to spray candidin + potassium dihydrogen phosphate or gibberellin + indole acetic acid + brassinolide to improve the cold resistance and freezing resistance in the sunny days after snow, which is conducive to the greening and jointing of wheat and lay a foundation for high wheat yield. Second, fruit trees It is recommended that after the heavy snowfall, the fruit growers should avoid snow and break the fruit branches. It can also spray 0.2%-0.3% urea solution +0.1%-0.5% potassium dihydrogen phosphate solution after snow to improve the resistance of the fruit trees. Absorption of nutrients and spring shoots. Third, greenhouse crops In greenhouse cultivation, in case of heavy snow, it is easy to cause snow damage, easy to crush the scaffolding, hinder crops from seeing light, and even freeze damage. Therefore, growers should take active measures to prevent the work. 1. Prevent snow from crushing the scaffolding and clear the snow in time If the amount of snowfall is large, it is especially necessary to check the scaffolding for a strong protective ground. Under the scaffolding in the protected area, temporary support - some sticks and other objects can be used as pillars to enhance the load capacity of the scaffold. If the snow on the grasshopper or shed film is large, it must be removed at any time to reduce the load on the scaffold. At the same time, it is necessary to pay attention to clearing the snow around the protected area in time to avoid the snow water flowing inside the protected area. 2. Avoid snow and wet grass. Put the grasshopper down on snowfall. In order to prevent the wet grass from wetting the grass, use the old shed film to wrap the grass sew before the snowfall, or add the old shed film and press it on the grass hoe after putting down the grass hoe. The insulation performance also makes it easy to remove snow. 3. Take scientific measures That is, when there is no snowfall during the day, the haystacks should be rolled up half or all, so that the plants can see the light. As long as the temperature of the shed does not drop, the time of seeing light can be extended as much as possible. If you can't roll the drafting, you can hang a few lights in the shed, and fill up the light every day for 2-3 hours. 4. Take “review†measures If the solar greenhouse does not uncover the grasshoppers for several days, when the snow stops, the "return" measures can be taken to uncover the grasshoppers at around 9 am, and the leaves on the top of the plants are found to sag slightly. Put the grasshoppers and other objects down to shading. After the young leaves of the plants return to normal, roll up the grasshoppers and other things to see the light. One day, you can roll the grasshoppers several times. After a few days, turn them back to the normal grass. 5. Strengthen crop management (1) Do not water or spray. (2) The temperature of the shed should be 3-5 degrees lower than that of the sunny day, and the temperature difference between day and night (about 10 degrees) should be maintained. If the grasshoppers are not uncovered for a few days, the night temperature should not be too high, in order to prevent the plants from excessive consumption of their own nutrients and lead to weakness. (3) Remove fruit and vegetables from mature fruits in time to reduce the nutritional burden of the plants. (4) Fumigation with smoked agent and spraying of foliar fertilizer can spray .05%-1% glucose solution or 0.2%-0.3% urea solution (5) Prevent the temperature from freezing and freeze. When the snow stops to be fine, care should be taken to take insulation measures or temperature increase measures in the protected area. The above is the precautionary work of the post-snow farming. This period of time is also called “cold springâ€. Many crops are subject to freezing damage. Farmers must be careful and take precautions to avoid unnecessary damage to crops.
