2023-08-04 19:08:38

Last week (October 18-24, 2010), precipitation in parts of Liaoning and Heilongjiang was 10-20 mm, and in some areas it was 20-50 mm or more. In some areas, the precipitation is below 1 mm, and there is no precipitation. Compared with the same period of the previous year, the precipitation in Zhou, Liaoning, Jilin and Heilongjiang is less than 80% or more. During this period, the average weekly temperature in most parts of the country was lower than that in the same period of the previous year.

This week (October 25-31, 2010), it is predicted that the strong cold air that hit China in the latter part of last week will continue to move eastward and southward in the early part of this week, and the temperature in the southeastern part of Northeast China will drop by 6-8 degrees Celsius. There will be small to moderate rain (snow) or sleet and partial heavy snow in the eastern and northern parts of the Northeast.

Agricultural and agricultural conditions that need to be paid attention to in Northeast China this week:

Greenhouse facilities, pastoral grazing, transportation, etc. should be well protected against wind or snow, grab the pre-frost flowers of cotton, and some areas of northeastern South China that have matured and not harvested (digging, mining), Chinese cabbage, sweet potatoes, apples, etc. Harvest in time (digging, mining) before catching the weather or frost, to avoid low temperature, frost and snow damage.
