摘　　要：以8年生漾濞大泡核桃幼林地为研究对象,以芋头、辣椒、玉米、茶叶4种作物为间种作物,采用实地采样和试验测定分析相结合的方法,对核桃林地不同间种模式下的土壤理化性质进行了比较分析,以期为探讨适合核桃林地的最佳间种模式及核桃高效栽培技术的集成提供理论依据。结果表明:间种能改善核桃林地土壤理化性质,且间种芋头的效果最好,为核桃林地最佳间种模式;其次是间种辣椒,为核桃林地比较适宜的间种模式;而间种玉米及茶叶,不利于改善核桃林地土壤理化性质。In order to provide theoretical basis for the study of the best integrated interplanting mode and cultivation technology for walnut forest land,taking 8-year-old young forest land of walnut plantation as research object,with taro, pepper,corn and tea crops as the intercropping plants, the effect of intercropping pattern on soil physical and chemical characteristics of walnut plantation were studied by field sampling and experimental determination. The results showed that intercropping with taro or pepper could improve the physical and chemical properties of walnut plantation, it was found that the effect of intercropping with taro was the best, next was pepper. Whereas intercropping with corn or tea was not benefitful to improve for the physical and chemical properties of soil.
