In order to fundamentally solve the problems of depletion of non-renewable energy and environmental pollution caused by the depletion of the non-renewable energy, development and utilization of clean energy become an important development direction for current resource development and energy structure adjustment, and development of renewable clean energy such as solar energy, wind energy, tidal energy and the like becomes a consensus. Photovoltaic power generation has the advantages of safety, no pollution, abundant resources, high energy quality and the like, is considered to be one of the most potential ways in the energy field, and the photovoltaic industry develops rapidly around the world, wherein China is the country with the fastest growth of photovoltaic power generation. With the large-scale start-up of the photovoltaic application market in China, land problems have become one of the important problems limiting the construction of photovoltaic power generation.
The selection of suitable cash crops and the planting mode thereof are the prerequisites for implementing the 'agricultural light complementation' system. Firstly, because the arrangement of the photovoltaic panel can obviously affect the illumination of farmland under the panel, the shading plants are preferably selected as main materials. Secondly, most photovoltaic power stations are built on barren mountains and barren lands, so that the selected plants are required to be drought-resistant and barren-resistant, and the method is suitable for simple and convenient farming. Finally, the selection of plants with high economic, ecological and social benefits is of great significance for increasing the income of farmers and solving the problem of poverty. After the complementary mode of agriculture and photosynthesis, through the exploration and steady development of the last decade, crops are cultivated more and more in variety, and at present, most of the crops are vegetables, flowers, mushrooms, dwarf shrubs and the like.
The oil peony is widely distributed in China and has strong ecological adaptability, the peony can grow at-30 ℃ in Mongolia in Jilin from North, has strong cold resistance, and also has certain humidity resistance and heat resistance in south, Anhui and Jiangzhe. The oil can grow on neutral or slightly acidic or slightly alkaline soil of peony, and can also grow on barren soil. The root system is developed, the thick root is fleshy root, the waterlogging tolerance is low, and the soil drainage is required to be good. The oil peony should be properly shaded as long as it is sufficiently sunny for growth. The oil peonies are dwarf shrubs, the plant height is 1.0-1.5 m, and the oil peonies are mostly interplanted with tall trees such as walnuts and shinyleaf yellowhorn, so that the land utilization rate can be increased, the economic benefit is increased, the tall trees can shade the oil peonies, and a good growth environment is provided. The oil peony can be temporarily dormant and stop growing at 28 ℃ above summer, but the plant body can not be damaged, and the oil peony can be released and can recover from growth when meeting a proper growth temperature.
