The Guizhou Meteorological Observatory estimates that from the 17th to the 20th, except for the southern margin of Guizhou Province and the cloudy days of the Chishui River valley, there are smog or freezing rain on cloudy days in most parts of Guizhou Province, and the freezing intensity is enhanced and the range is expanded.
On the 21st to the 22nd, the province was dominated by cloudy days and there was light rain at night. The central and western parts of the province had freezing rain, and the freezing range tended to gradually decrease.
Based on this, the following agricultural production proposals are proposed:
(1) Continue to do the thermal insulation work of the animal husbandry shed, and timely add the concentrate to enhance the ability to keep out the cold.
(2) On the 17th to the 20th, the range and intensity of freezing will be expanded. For the cold and frost-proof work of fruit trees and seedlings to be particularly strengthened in the south and southeast, the anti-freeze and cold-proof measures for fruit trees: high-cultivation soil can be used, and the tree trays can be covered with straw or film. The film covers the canopy, the trunk is bandaged, whitened, and the orchard is covered with husks, wood chips, and the like.
(3) On the 17th to 20th, the early-maturing vegetables in the south, southeast and southwest of Guizhou should strengthen the anti-freezing work. If the film has been covered, it is necessary to check whether the film leaks air. If there is no cover film, it should be covered in time.
