        近日，重慶首個光伏提灌站——梧桐寺光伏提灌It was put into use in Qingjiang Town, Rongchang District. Different from traditional electric irrigation, this irrigation station uses solar energy to generate electricity through photovoltaic modules to provide power for pump units. While providing irrigation water for farmland continuously, it also saves farmers a lot of water costs. A reporter from Chongqing Daily saw in Zhulin Village, Qingjiang Town, that this photovoltaic irrigation station was built in a paddy field, and the blue photovoltaic panels reflected light in the sun. After the staff turned on the power generation equipment, the water pump of the irrigation station started to work, pumping the water into a reservoir on the top of a hillside. After the reservoir was full of water, the water was transported to the fields through pipes. This photovoltaic irrigation station has an installed capacity of 7.5KW and is composed of 36 photovoltaic panels. It can lift 20 cubic meters of water per hour, and can guarantee the surrounding 500 acres of farmland water.

       2016年，重慶市在大足、榮昌、梁平等12個區The county piloted a comprehensive reform of agricultural water prices, trying to solve the problems of extensive agricultural irrigation, insecure water supply, and difficult management and maintenance in the past. Yang Yi, head of water conservancy of Rongchang District Water Affairs Bureau, said that the construction of a photovoltaic pumping station in Zhulin Village, Qingjiang Town is a supporting project for piloting the comprehensive reform of agricultural water prices in the district and building a high-efficiency water-saving project. Last year, in conjunction with the comprehensive agricultural water price reform project, Rongchang District, through water-saving renovations, laid pipelines from reservoirs and Shanpingtang water intake points to farmland, and installed smart gate valves and meters in the fields. The farmland not only drank "tap water" , and also achieve accurate metering of water bills. According to Yang Yi, compared with traditional electric irrigation, solar energy irrigation not only has low operating costs, low energy consumption and emissions, and high water pumping efficiency, but also can be unattended, saving a lot of management and maintenance costs. Since there is no electricity bill for the photovoltaic pumping and irrigation station, the water bill for each cubic meter of the beneficiary area can be saved by about 8 cents after it is put into use. Lan Yunxia, the head of the Jiufeng Rice Cooperative in Rongchang District, told a reporter from Chongqing Daily that in order to avoid water competition with villagers during the peak season of rice transplanting, he had already been busy preparing the land and irrigating it in this season to prepare for the rice transplanting a month later. However, after the photovoltaic irrigation station is put into use this year, water can be drawn at any time, and there is no need to prepare for spring ploughing a month in advance. Not only that, the use of photovoltaic irrigation stations has also greatly reduced his water bills. In the past, he used the three-level irrigation method, and he spent about 110 yuan per mu of rice field in water costs every year. Today, the rice field water is metered according to the meter, and the photovoltaic irrigation saves the water fee. He only needs to pay about 20 yuan per mu of rice field to meet the water demand during the harvest period.

      Since the pilot comprehensive reform of agricultural water prices, Rongchang District has continued to tighten the "faucets" of agricultural irrigation, Gezhen Street promoted the reform of 320,000 mu of farmland. In the reform pilot areas, the water expenses of farmers have dropped from 40 yuan per mu to 25 yuan per mu, and the irrigation water utilization coefficient has increased from 0.469 to over 0.85 now. This year, Rongchang will achieve full coverage of the comprehensive reform of agricultural water prices in 21 towns and streets in the district.
