Due to the high temperature after the winter this year, the wheat grows vigorously, the leaves are green, and the winter warms the wheat growth process more than in previous years. In some areas, the wheat grows vigorously and has poor cold resistance. On the evening of December 7th to the 8th, the city welcomed sleet weather, and the amount of rain and snow was large. After this large-scale snowfall, the decrease in temperature is very beneficial to the current wheat production in the city. First, the snowfall is conducive to the increase of soil moisture. Second, the snowfall cooling can suppress winter diseases and insect pests, killing part of the overwintering eggs, and playing a certain role in pests and diseases. Prevention and Control; Once again, the so-called Ruixue trillion years, the snow cover to increase the insulation and moisturizing effect, the winter wheat has a good drought-resistant exercise, suppressing some of the prosperous wheat, and cover the quilt, conducive to wheat cold and winter.
However, the decrease in temperature may cause frost damage. Therefore, effective measures must be taken in time to reduce risks and improve field management. Do not blindly water the wheat fields suitable for lyrics, so as to avoid the risk of freezing and suffocating the roots of wheat. After the snow melts, the wheat field and the general wheat field should be suppressed and cut in time to reduce evaporative loss, enhance the ability of wheat to resist cold, and promote wheat growth. Root growth; For wheat seedlings that are prone to frost damage, it is possible to use organic fertilizers, miscellaneous fertilizers, and comminuted crop stalks to cover the external insulation against frost and keep the seedlings safe for the winter.
