摘要： 为了科学的选择较好经济效益的光合利用高效型小豆—玉米间作模式，采用单因素试验设计，研究了6种小豆—玉米间作模式下，小豆花荚期的光合特征参数以及收获后综合经济效益。结果表明，小豆光合特征参数中，其Pn、Tr值均以无遮荫条件下小豆（对照CK1）最高，5:2间作模式下小豆的Pn、Tr值要高于其他间作模式的小豆，Cs值则低于其他间作小豆。相关性分析表明，当光合有效辐射强度增大，导致净光合速率升高，蒸腾速率增大、气孔导度增大、胞间CO2浓度减小。综合经济效益表明，5:3间作模式收益最高，达31378元/hm2，最终结果分析表明，5:3的小豆—玉米间作模式，适合在山西中部地区进行推广种植。

Abstract: Photosynthesis is the basis of plant growth and development, but also the determinants of the level of plant productivity. Under six adzuki bean-corn intercropping mode, an single factor test was adopt to study photosynthetic characteristic parameters in flower pod stage of adzuki bean and composite economic results in harvest. The results indicated that, the Pn and Tr value of control were the highest, under intercropping mode, (5-2) Pn and Tr value were the highest than others, Cs was opposite. The control was in no shade condition. Correlation analysis showed that, when the intensity of photosynthetic active radiation increases, leading the increasing of net photosynthetic rate, transpiration rate, stomata conductance and the decreasing of intercellular CO2 concentration, the composite economic benefits results showed that the intercropping mode 5-3 was the highest. It reached 31378 yuan/hm2. The final results showed that, it was adaptive for cultivation in midland region in Shanxi Province.
