Yunnan has new tricks to fight drought, solar energy technology eases water difficulty

The reporter learned from the Department of Science and Technology of Yunnan Province on the 22nd that in order to alleviate the difficulties in water and water intake caused by the three-year continuous drought in Yunnan, the department planned and implemented scientific and technological drought-resistant projects such as solar photovoltaic water intake systems and drip irrigation systems, which effectively relieved orchards and vegetable fields in Yunnan mountainous areas. Water-saving planting and drinking water for humans and animals. The project is located in Yunnan Zhaotong, Qujing, Wenshan, and Kunming in the 4 most drought-stricken areas. A solar photovoltaic water intake system and a 100,000-meter drip irrigation water-saving system are installed at each point. The solution is solved by ditches and underground water intake. Local human and livestock drinking water and water-saving irrigation problems. Among them, the largest drought-resistant solar photovoltaic water intake station in Yunnan Province was built in Xichou County, Wenshan Prefecture, and the solar photovoltaic water intake has a lift of 120 meters and can pump 25 tons of water per hour, solving the drinking water problem of 432 local people and 90 large livestock.   It is understood that the solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaic water intake is not only beneficial to the people, but also low-carbon and environmentally friendly. It has strong promotion and application value in mountainous areas. The project was successfully completed a few days ago, which largely solved the water-saving planting and drinking water problems of local orchards and vegetable plots.   So far, the continuous drought in Yunnan has caused 8.76 million people to be affected, 4.94 million people have difficulty in drinking water, and the area affected by crops reached 12.51 million mu. The province’s direct economic losses due to drought exceeded 6.1 billion yuan. According to the Yunnan Meteorological Bureau, the rainy season in most parts of Yunnan Province will begin in late May. The current is a critical and difficult period for drought in Yunnan.
