摘　　要：为了充分利用雷竹新造林地空间,扩大种植效益,对雷竹/花生、雷竹/芝麻、雷竹/红薯3种套种模式和雷竹纯林林地的土壤物理化学性质、雷竹造林成活率和出笋个数进行比较研究。结果表明:雷竹新造林地套种花生能够显著降低土壤容重和速效P含量,增加土壤孔隙度、碱解N、速效K、有机质含量,促进雷竹造林后第二年出笋个数的提高,同时不影响雷竹造林成活率,能够充分利用雷竹新造林地空间,填补雷竹新造林地的经济效益空白,达到以耕代抚,以短养长的目的。In order to make full use of the new afforestation of Phyllostachys praecox and expand planting benefit,three interplanting patterns of Phyllostachys praecox+peanut,Phyllostachys praecox+sesame and Phyllostachys praecox+sweet potato were compared with the pure afforestation of Phyllostachys praecox in soil physical and chemical properties,the survival rate of Phyllostachys praecox and the number of shoots produced.The results showed that the pattern of Phyllostachys praecox intercropped peanut significantly reduced the soil bulk density and available P level,enhanced soil porosity,and alkali-hydrolyzable N,available K and organic matter contents,improved the number of shoots in the second year after afforesting,meanwhile keeping the survival rate of Phyllostachys praecox afforestation,which can make full use of the new afforestation of Phyllostachys praecox,fill the blank of economic benefits in the new afforestation of Phyllostachys praecox and achieve the goal of farming instead of tending,short investment return period subsidizing long investment return period.
