摘　　要：研究了秸秆覆盖和薄膜覆盖对山地甜柿园土壤水热变化规律、土壤理化性状和树体生长结果的影响。3年定位试验结果表明,覆盖提高了果园各层土壤含水量和土壤养分的有效性,改善了果园土壤的结构和性状、增加了植株根系数量,对叶片数量、质量、叶片大小以及枝条抽生数量、质量和树冠大小、叶面积系数等指标均有良好的优化作用。秸秆覆盖有降低生长季节土温和提高冬季土温的作用,薄膜覆盖有增加土温的作用。This paper deals with the effect of maize stalk mulch and plastic film covering on soil heat variation and soil chemic and physic characteristics,tree growth and fruiting in mountain persimmon orchard.Three years'trial showed that mulch increased the moisture of soil layers and the availability of soil nutrients,improved the soil structure and characteristics,promoted the plant root quality,with a role of optimization on leaf number,quality,size,and shoot number,quality as well as tree canopy size,leaf area ratio.Maize stalk mulch had a role of reducing soil temperature in summer and increasing soil temperature in winter.Plastic film covering had a role on increasing soil temperature.
