摘　　要：地面覆盖能起到增肥、保墒、防热、预防根系冻害和改善土壤理化性状的作用,促进土壤有机质和营养物质的积累、分解和转化,从而复壮树势,提高果品的产量和质量。为给有关地面覆盖对经济林木的影响的研究提供参考和依据,综述了有关地面覆盖对农作物及果园土壤中水、肥、气、热及微生物等肥力因子的影响方面的研究成果和研究进展。Ground cover has the function of increasing fertility, conserving soil moisture, thermal protection, preventing root system freeze injury and improving soil physical and chemical properties, and can promote accumulation, decomposition and transformation of organic matters and nutrients in soil. That can make tree vigor rejuvenate, and improve output and quality of fruit. In order to provide a basis for researches on effect of ground cover on nonwood forest trees, research progress on effect of it on crops and some fertility factors in soil of orchard was reviewed.
