为探讨种植菊苣后对柑橘果园土壤性质的影响，探明清耕和生草2种种植模式下柑橘果园土壤理化性状的差异。结果表明：柑橘园种植将军菊苣后，0～15 cm 土层土壤温度较对照均显著降低，且表层土壤表现更显著；生草园0～20 cm 土层 pH 和有机质含量均提高，表土层增加幅度一般较深层土壤差异更显著，土壤容重显著降低。说明，果园生草可有效改善果园小气候及土壤物理性状，产量略降低，但生草果园总的经济效益大幅度提高。%Two cultivation patterns of clean tillage and growing grass were compared in citrus orchard to study the effects of interplanting C.intybus in citrus orchard on soil physical and chemical properties. The results showed that interplanting C.intybus can reduce soil temperature of the soil layer with 0~15 cm significantly,increase soil pH value and organic matter content of the soil layer with 0 ~ 20 cm and reduce soil bulk density significantly compared with CK.In conclusion,interplanting C.intybus in citrus orchard can effectively improve microclimate of citrus orchard and soil physical property,and the fruit yield of citrus orchard under interplanting C.intybus pattern decreases slightly but its total economic benefit is increased by a large margin.
