基于固废堆肥施用的沙土养分调节及改性效能研究

Nutrient Regulation and Modification Efficiency of the Sandy Soil Based on the Solid Waste Compost Application

固废堆肥以其经济高效的特点可作为良好的土壤有机改良剂。在控制安全施用量的前提下,将堆肥产物与沙土以不同比例复混极建沙肥复合基质,幵通过盆栽试验,从理化性质、养分含量、微生态特征、植物生长状况等角度全面考察了新基质的土壤-植物效应,综合评价了施用固废堆肥对沙土的养分调节及改性效果,指出固废堆肥对沙土改良具有较大的应用潜力和实用价值。

Solid waste compost can be used as a good organic soil conditioner due to its economical and efficient characteristics. Under the premise of controlling the application rate at a safe range, the compost and the sandy soil were compounded in different proportions to construct the sand-fertilizer composite matrix, and the pot experiment was carried out to comprehensively examine the soil-plant effects of the matrix from the perspectives of physicochemical properties, nutrient content, micro-ecological characteristics and plant growth status. The nutrient regulation and modification effects of solid waste compost on sandy soil were systematically evaluated. The results showed that solid waste compost has great application potential and practical value for sandy soil improvement.
