Snow does not cool snow, cold winter crops in Guizhou need to be protected against freezing after snow

5 December 17th, 0 ℃ temperature line in the eastern region of our country continues southward to southern Guizhou, northern Guangxi and Guangdong middle line, the strong cold air cooling large amplitude wide range of snowfall, strong intensity; minimum temperature of local mountain When the temperature reaches minus 5 °C, it is easy to cause the leaves of rapeseed and open vegetables to freeze, which is unfavorable for growth. Because of the high snowfall intensity, the branches of fruit trees and economic forests can be broken, and a few crops can be collapsed. In addition, low temperature on livestock and aquatic products Farming also has an adverse effect.

The Central Meteorological Observatory predicts that from the night to tomorrow, the sporadic rains in the southwestern part of Guizhou Province will turn cloudy, and the rest of the province will have sporadic light rain on cloudy days; from the night of the 20th to the day of the 21st , there will be light rain in the evenings throughout the province, cloudy days during the day.

From 23 to 24 , due to the influence of cold air, there was light rain on cloudy days in the whole province, and the temperature dropped significantly. 5 to 10 degrees.

As the saying goes, snow does not cool snow, cold winter crops, vegetables, flue-cured tobacco, etc. should be treated with straw, film covering, etc. to prevent cold and freeze, while adding hot phosphorus and potassium fertilizer, improve crop cold resistance, reduce cold (freezing) Harmful impact. The fruit trees can adopt the measures of whitening the tree trunk, covering the tree plate and cultivating the soil with trees to enhance the cold and frost resistance of the plants, and can be smoked and frozen at night; the fruits such as bananas and alfalfa can be bagged to prevent cold (freezing). Rape, field vegetables, green manure, citrus park timely clearing ditch drainage, preventing freezing damage caused by water accumulation in the field. The melons and vegetables and greenhouses cleaned up the snow, water and ice on the shed in time, and sealed and strengthened the greenhouse. The poultry and livestock pens are kept dry, and the padding, rice husk, hay and other litter are properly added. Warm food, warm water and appropriate feeding times are added to improve the cold resistance. In addition, timely cropping of crops after rain and snow weather is also a good way to ensure crop growth.
