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。 The effects of straw mulching and film mulching on the changes of soil water and heat, soil physical and chemical properties and tree growth were investigated. The result of 3-year positioning test showed that the mulching improved the soil moisture content and the soil nutrient availability in the orchard, improved the structure and traits of the orchard soil, increased the number of roots in the plant, the leaf number, the quality, the leaf size, Quantity, quality and canopy size, leaf area index and other indicators have a good optimization. Straw mulching has the effect of reducing the soil temperature during the growing season and increasing the soil temperature in winter, and the film covering has the effect of increasing soil temperature.
