【Explanation】 Since Liangshan Yi Autonomous Prefecture in Sichuan Province is rich in light resources, photovoltaic power generation projects are spread across counties and cities in the country. In recent years, Liangshan Prefecture has developed photovoltaic agriculture as a new form of agriculture according to local conditions, combining solar power generation, modern agricultural planting and breeding, and efficient facility agriculture.

  [Explanation] In May, Tongwei invested and built an area of ​​1,300 mu in Tongwei, Sichuan ’s Xide County Nongguang Muguang Integrated Photovoltaic Poverty Alleviation Power Station The solar energy is continuously converted into electrical energy, and the flocks are shuttled between the photovoltaic panels to eat grass leisurely.

  【Commentary】 Wei Qigang, the head of the power station, introduced that the installed capacity of the photovoltaic area of ​​the power station is 30MW (megawatt), which was officially put into operation on December 28, 2018 and connected to the grid. Thanks to the light resources of Liangshan Prefecture, the location of the power station can use about 1400 hours of sunshine per year, and the annual power generation can reach 42 million degrees. The power station has also established a cooperative with the village committee of the Valxi General Village and Xide County Agricultural Tourism Investment Co., Ltd. to develop the breeding industry and achieve "multiple income in one place".

  [Same period] (Wei Qigang, Project Director of Poverty Alleviation Power Station Project of Tongguang, Xied County, Sichuan Province) The number of goats raised in the entire photovoltaic area is about 60, and the scale is gradually increasing. The height of our module below the ground is one meter five. If you breed small animals like this, it will generate electricity for our power plant, and it will have no effect on these components. The next step is to plan to plant Xiyin cash crops under the photovoltaic modules of the power station, and then to further increase employment in the local village, as well as income. This will bring them more benefits.

  [Commentary] Asiwuya, who is grazing sheep on the hillside of the power station, is a local poor household of the Lika, who has been able to earn 1,500 yuan a month after being hired as a herdsman by the Varsi General Village Cooperative.

  [Same period] (Axi Wuxia, a herdsman of the power station) After being invited by the cooperative to herd sheep, they don't have to go out to work, and they can also transport the sheep dung home to fertilize the pepper tree. Sheep are laid in the power station, there are fences everywhere, the sheep will not run around. The grass under the photovoltaic panel grows tall, and the sheep are fed to be fatter than the sheep fed at home.

  [Explanation] The integrated photovoltaic poverty alleviation power plant in Xide County's agriculture, light and agriculture is just a microcosm of Liangshan's exploration and development of photovoltaic agriculture. Tongwei's "Fish and Light Integration" Demonstration Park, located in Xichang City, the capital of Liangshan Prefecture, is the first "Fish and Light Integration" project in Sichuan Province. Luo Hu, the head of the park's power station, introduced that the park includes photovoltaic power plant areas, management and control areas, and fishery culture areas. The project plans to create a clean water power generation, modern underwater breeding, fish manure recycling for organic cultivation, and organic cultivation to promote a circular economy model of ecological agriculture, sightseeing and tourism.

  [Same period] (Luo Hu, Director of Xichang Tongwei "Fish and Light Integrated" Demonstration Park Power Station) (power station) has more than 78,000 modules, and the daily power generation is about 100,000 kWh (electricity), and the annual power generation is 3100 Ten thousand (kWh). Ever since we built the power station and everything has been properly managed, the ecology here is also better. There are many grey herons and egrets here, (and) mandarin ducks and wild ducks. From December of the first year to February of the following year, there are basically five or six thousand wild animals on the water surface like us. On the water, we also try to grow some water vegetables.

  [Commentary] Xie Wei, director of the park ’s farm, told reporters that although the park ’s reservoir covers an area of ​​more than 620 acres, the area of ​​facility fishery culture is only about 4.2 acres. It mainly breeds crucian carp, carp, and perch. The annual output is about 400,000 kg. In addition to local sales in Xichang, it is also sold to Chengdu, Panzhihua and other places, with an annual output value of 2 million yuan.

  [Same period] (Xie Wei, head of the farm of Xichang Tongwei "Fish and Light Integration" Demonstration Park) Our facility breeding is to concentrate the breeding density of the outer ponds into the facility to raise. In the case of Waitang, it is mainly used as a purification area for water quality, while silver carp and silver carp are originally filter-feeding fish, and their effect on regulating water quality is relatively obvious.

  【Explanation】 In the opinion of Li Shijie, deputy director of Xichang Development, Reform, and Information Bureau, jumping out of the traditional photovoltaic power generation model and combining the photovoltaic energy industry with the breeding industry is an effective attempt to maximize resource utilization.

  [Same period] (Li Shijie, Deputy Director of Xichang Development, Reform, and Economic Information Bureau) The photovoltaic industry and the aquaculture industry have actually formed a construction equivalent to integration, which actually saves resources and maximizes the effective utilization of resources. Change. It is equivalent to (comparison) with the traditional photovoltaic industry. If the ground (only) is used for photovoltaics, this land is directly wasted, but this kind is used for photovoltaic power generation above, and the breeding industry below, space utilization, etc. In all aspects, I think this is a good thing.
