Affected by strong cold air, the lowest temperature on the 7th morning reached 0~4°C in the western part of the country, and the high-altitude mountain area was below 0°C, with frost or ice. This is a relatively obvious cooling process since the winter of our province. How to do the anti-freezing work of crops?
