The drought in Hunan continues to increase! There is no effective rainfall in the worst area for more than 68 days. How to minimize the loss?

Since the beginning of this year, China and even the whole world have been affected by extremely high temperature weather. This year's group high temperature weather has the characteristics of wide range, long length and long duration. So this year, different degrees of high temperature frequency have appeared in all countries in the world. We all know that high temperature will bring drought, which has a very serious impact on many countries and regions, especially on crops.

However, after autumn, there are still different degrees of rainfall in many places, and the drought has eased slightly. However, due to the high temperature epidemic this year, there is no obvious rainfall process in Hunan Province. At present, the drought in Hunan is still worsening, and it is said that it has not rained for more than 68 days in the most serious places. At present, according to the development trend of drought in Hunan Province, it is estimated that serious hydrological drought may occur in about 80% of the province, and extreme hydrological drought may occur in 35% of the province. Drought is affected by rainfall and incoming water.

At present, the storage capacity of large reservoirs in Hunan Province is small, and the continuous sunny, hot and high temperature weather will lead to drought and water shortage in farmland and a large number of crops will be reduced. It's like a hunger stone in Europe. Affected by this year's hot weather, Europe's hunger knowledge has been exposed again. It can be seen from the Hunger Stone that if the drought continues, it will definitely lead to the reduction of our crops, and then we will face the food crisis.

At present, the drought in Hunan continues to increase. How can we minimize the loss?

For the dry weather in Hunan, the crop area is large enough to reduce production. Therefore, all localities should repair the irrigation channels damaged by water, and invest in supporting facilities such as pumps, generators and well drilling machines to ensure timely irrigation of farmland. In addition, water can be stored by damming rivers and discharged into ponds through temporary waterways. In addition, in order to do a good job in drought prevention, drought prevention and drought relief, we should pay close attention to the weather change form, seize the favorable opportunity to carry out artificial precipitation enhancement, strive to open up new water sources for Hunan Province, and at the same time strengthen the unified management of water quantity and accurately do a good job in water storage and water conservation.
