摘　　要：为提高枣园的生态环境效益和生产潜力,进行了枣园间作小麦与单作小麦对比试验。结果表明,枣园间作小麦有效地降低小麦田干热风的发生;枣园间作区土壤容重、温度降低,土壤总孔隙度、毛管孔隙度、毛管持水量、水分含量均显著增加(P<0.05);枣园间作区土壤细菌、放线菌、真菌、纤维分解菌、固氮菌的数量以及有机质、全氮、速效磷、速效钾均增加显著(P<0.05)。枣园间作小麦对土壤物理性质、土壤微生物、土壤养分具有明显的改善作用。To improve ecological efficiency of Chinese jujube orchard and to further dig out its productive potentiality, comparative tests between intercropping wheat with Chinese jujube and single-cropping wheat were conducted. The results showed that intereropping wheat with Chinese jujube could obviously decrease dry-hot winds in wheat field; Bulk density and temperature of the soil were decreased, and the total porosity, capillary porosity, capillary moisture capacity and moisture capacity were apparently im- proved （P〈0.05） ; the number of bacteria, actinomyees, fungus, cellulose-decomposing bacteria and ni- trogen-fixing bacteria in soil was increased, and the content of organic matter, total N, available phos- phorus and potassium in soil were raised （P〈0.05）. Intercropping wheat with Chinese jujube can obviously improve soil physical properties, soil microorganisms and soil nutrient.
