摘　　要：本研究通过设置薄壳山核桃幼林纯林经营(CK)以及间种花生、大豆、玉米、玉竹,开展为期2年的间种试验,分析不同间种模式对薄壳山核桃幼林保存率、生长指标和经济效益的影响。结果表明:间种花生、大豆、玉米、玉竹4种间种模式下薄壳山核桃幼林保存率均低于CK,但合理的间种模式可以降低这种负面影响;间种花生、大豆、玉竹3种间种模式下薄壳山核桃生长指标均高于CK,间种玉米模式下薄壳山核桃生长指标低于CK,表明间种作物的选择对薄壳山核桃幼林的生长有一定影响;不同间种模式下薄壳山核桃幼林年均经济收益差别明显,经济投入和对作物种植管理的技术要求差别也较大,林农要根据自身经济状况和技术条件选择合适的间种模式。In this study,we conducted a 2-year intercropping experiment to analyze the effects of different interplanting modes on the preservation rate,growth indicator and economic benefit of pecan young forest by setting up pure forest management(CK)and interplanting peanut,soybean,corn and jade bamboo in pecan young forest.The results showed that under the four intercropping modes of interplanting peanut,soybean,corn and jade bamboo,the preservation rate of pecan young forests was lower than that of CK,but a reasonable intercropping mode could reduce this negative effect.Under the three intercropping modes of intercropping peanut,soybean and jade bamboo,the growth indicators of pecan were all higher than those of CK,while under the intercropping mode of intercropping corn,the growth indicators of pecan were lower than those of CK.It indicated that the selection of intercropping crops had a certain impact on the growth of pecan young forest.Under different intercropping modes,the average annual economic income of young pecan forests was significantly different,and the economic input and technical requirements for crop planting and management were also significantly different.Therefore,forest farmers should choose the appropriate intercropping mode according to their own economic conditions and technical conditions.
