摘　　要：广西喀斯特地形广布,石漠化问题严重影响当地经济发展。在喀斯特地区发展合理的复合种植模式既能带来明显的经济效益,又能对石漠化治理产生积极作用。大豆是广西喀斯特地区常见的经济作物,花椒的引进及推广也成为喀斯特地区扶贫产业之一。在花椒生长早期于行间设置3种大豆套种密度,分析其对花椒生长特性、叶片含水量、光合能力的影响。结果表明,套作密度大的处理(大豆45株/m^2)花椒叶片含水量较高,植株生长较好;花椒套种大豆既能获得大豆短期收益,也具有增强花椒光合作用,促进花椒生长的作用。The karst terrain in Guangxi is widespread,and the problem of rocky desertification has seriously affected the local economic development. The development of a reasonable compound planting model in karst areas can bring significant economic benefits and also have a positive effect on the management of rocky desertification. Soybean is a common cash crop in the karst area of Guangxi,and the introduction and promotion of Zanthoxylum bungeanum has also become one of the poverty alleviation industries in the karst area. In the early growth stage of Z. bungeanum,three soybean interplanting densities were set between rows,and their effects on the growth characteristics,leaf water content,and photosynthetic capacity of Z. bungeanum were analyzed. The results showed that the treatment with high intercropping density(45 soybeans/m^2)had higher water content in the leaves of Z. bungeanum and better plant growth;interplanting Z. bungeanum can not only obtain short-term benefits of soybeans,but also enhance the photosynthesis of Z.bungeanum and promote the growth of Z. bungeanum.
