摘　　要：间种不仅提高了复种指数、光能利用率和林地经济效益,而且间种物伸展的枝叶或藤蔓自然覆盖裸露地面,降低了土壤温度,缓和了暴风雨对土壤的直接侵蚀,减少了水、土、肥的流失;收获后,其剩余部分还可以回归林地,对增加林地的养分含量,改善林地的土壤结构等方面都有良好效果。笔者综述了间种对林地土壤水、肥、气、热等肥力因子及树体生长、果实品质和经济效益的影响,为探索间种对果林的影响提供参考和依据。Interplanting can not only improves the cropping index,light energy utilization and economic benefit of forest land,but also stenters branch leaves or bind can natural cover the barrens,reduces the soil temperature,mitigates the storm direct erosion on the soil and reduces loss of the water,soil,and fertilizer;After harvest,it＇s remainder can return to the forest land which have a good effect on the soil nutrient content＇s increasing and soil structure improving.The authors summarizes the effect of interplanting on the soil fertility factors of water,fertilizer,air and heat etc.,the tree growth,the fruit quality and the economic benefit,and it provide the reference and basis for the exploration of the effect of interplanting on the fruit forest.
