摘　　要：[目的]完善以高原黄粉虫养殖为区域特色的种养循环体系,提升大棚土壤质量。[方法]在西藏洛扎县分别选取3个施用黄粉虫粪为主的养殖废弃物的大棚土壤,并以周边农田土壤作为对照,测定并比较土壤的基本农化特性、容重、孔隙度和土壤颗粒组成等理化性质的差异。[结果]3个采样点施用黄粉虫养殖废弃物的大棚土壤的有机质含量、有效磷含量、毛管孔隙度、田间持水量和小粒径土壤颗粒(<0.05 mm)占比显著高于周围农田土壤;而pH、土壤容重和大粒径土壤颗粒(>0.05 mm)占比显著低于周围农田土壤。[结论]在西藏高原地区,施用黄粉虫养殖废弃物具有通过提高土壤有机质含量提升土壤肥力,通过改变土壤颗粒组成改良土壤结构的潜力。[Objective]To improve planting and breeding cycle system with regional characteristics based on Tenebrio molitor cultivation in plateau area,and soil quality in greenhouse.[Method]Three greenhouse soils applied with tenebrio molitor breeding wastes(including frass and insect molt)in Lhozhag County,Xizang,and the surrounding farmland soils were used as controls.Differences in physical and chemical properties,such as basic agrochemical properties,bulk density,porosity and soil particle composition of the soils were measured.[Result]Soil organic matter content,available phosphorus content,capillary porosity,field water capacity and proportion of small particle size soil particles(<0.05 mm)in the greenhouse soils treated with tenebrio molitor breeding wastes at the three sampling points were significantly higher than those in the surrounding farmland soils;however,pH,soil bulk density and the proportion of large particle size soil particles(>0.05 mm)were significantly lower than the surrounding farmland soils.[Conclusion]Application of tenebrio molitor breeding wastes could improve both of soil fertility by increasing soil organic matter content,and soil structure by changing the composition of soil particles in Tibetan Plateau.
