农光互补模式对海州露天矿排土场土壤的影响
Effect of the Agricultural and Photovoltaic Complementary Mode on the Soil of the Haizhou Open-Pit Mine Discharge Field
摘要
Abstract
In order to investigate the impact of photovoltaic power plants under the operation of the agricultural and photovoltaic complementary mode on soil properties,in this study,taking four areas,namely,the corn area,the buckwheat area,the natural recovery area,and the surrounding control area in the photovoltaic power plant in the Haizhou open-pit mine discharge field in Fuxin city in two different periods of the autumn of 2023 and the spring of 2024,the physicochemical property indexes of the soil were measured and the correlation analysis of the properties was conducted.The results showed that compared to the autumn of 2023,the wet density,moisture content,and bulk density of the soil in the four areas in the spring of 2024 increased to different degrees,and the water holding capacity,total porosity,capillary porosity as well as non-capillary porosity of the soil decreased to different degrees.The soil pH,electrical conductivity,and organic matter content of the soil increased to different degrees,and the alkali hydrolyzed nitrogen,available phosphorus and available potassium content of the soil decreased to different degrees.Except for pH,the nutrient content of the soil planted with corn and buckwheat in the two periods were higher than those in the natural recovery area and the surrounding control area,and the physical properties of the soil in the four areas did not differ significantly.The results of the correlation showed that the content of alkali hydrolyzed nitrogen and available potassium which promoted plant growth had a greater influence on the physicochemical property indexes in the soil,and could be used as an important index to improve crop yield and soil quality.In conclusion,planting corn and buckwheat crops under the agricultural and photovoltaic complementary mode could improve the soil quality in the open-pit mine discharge field and was worth promoting and using locally.关键词
