Strengthen forecasting scientific prevention

"To cool down, go to the base and look at the greenhouse." Vegetable grower Li Qinfang immediately told the wife who was cooking after seeing the weather forecast message.

Li Qinfang is a vegetable grower in Xundian County, Yunnan Province. There are 300 acres of vegetable greenhouses in the family. The oily wheat in the field has entered the harvest period.

“Agricultural weather forecast has helped us a lot.” Li Qinfang said that in the past, it was more about relying on experience to deal with climate change. But often when the measures are taken, cold waves and rain have already occurred. Now with agricultural weather forecasting, defensive measures can be taken in advance.

According to the meteorological data of Yunnan Province, it is expected that cold air will begin to affect northeastern Yunnan on October 28, and sleet will occur in high altitude areas, and will be advanced to Yuzhong area on the 29th.

"Sudden cooling has a great impact on public life. The public should prevent respiratory diseases and cardiovascular and cerebrovascular diseases." Yunnan meteorologist Guo Rongfen said. Guo Rongfen believes that the moderately strong cold air process will have an adverse impact on the autumn harvest and autumn, and agricultural production should be well protected against cold and heat in advance.

Some experts have warned that there have been rainy and cool weather in the Jianghuai area, and precautions should be taken as soon as possible to prevent the accumulation of agricultural disasters.

Huang Zhimin, an expert from the Jingzhou Agricultural Meteorological Experiment Station of the China Meteorological Administration, introduced the Jianghan Plain as an example. Since mid-October, the average daily temperature here has dropped to below 14 °C to 13 °C. After the cold air continues to replenish in the future, the above areas The average daily temperature will not only fall below 10 °C. In early November, like the north of Hubei, the eastern part of Jianghan Plain, and the northern part of Jianghuai, early frost may occur. If it is not prevented, crops may freeze.

He said that the more serious is the continuous rainy and cooling weather in the previous period. It has caused the mature double-season late rice and corn in the Jianghuai area to be harvested. The wheat planting is postponed and the rapeseed in the seedling stage is damaged. "According to the forecast, this weather will continue. If you do not take precautions, the disaster will be more serious and the scope of the disaster will continue to expand."

To this end, Huang Zhimin suggested that the relevant areas should be prepared for prevention as soon as possible. Specific measures that can be taken include: For rapeseed and already-sown wheat, farmers should pay attention to cleaning up the “three ditch” filter water to remove stains, in order to facilitate the whole seedlings. Wheat should use the rain in the gap or the weather after the rain, grasp the seeding, and strive for the semi-winter varieties before November 5, the spring varieties are planted before the 10th, in order to facilitate early fast-food, safe winter.
