在枣粮间作模式下对间作作物的物质积累及产量成因进行对比分析，以玉米品种先育335、高粱品种沈杂5号为试材，分别对其在出苗后45、60、75、90 d和105 d的净光合速率、干物质积累、产量构成因素、株高和茎粗等指标进行了测定与分析。结果表明：在枣粮间作模式下，玉米和高粱分别在ZY4和ZG8模式下粮食产量最高；高粱在各生育时期内的光合速率均高于玉米，在不同生长时期内差异较小，相对玉米可适当密植；在ZY4和ZG8的模式下玉米和高粱干物质积累平均速率高，为高产量的形成奠定物质基础；穗数和粒重受密度影响较大，穗粒数影响较小，ZY4和ZG8模式下枣树、玉米、高粱三者配置模式较好。

The study aims to investigate the dry matter accumulation and yield components of maize cultivar Xianyu 335 and sorghum cultivar Shenza 5 under Jujube-cereal intercropping .The net photosynthetic rate ,dry matter accumula-tion ,yield components ,plant height and stem diameter were measured on 45 ,60 ,75 ,90 d and 105 d after germina-tion .The highest yield of maize and sorghum were detected for ZY4 and ZG8 pattern ,respectively .Generally ,the net photosynthetic rate of sorghum were higher than that of maize during growth periods;however ,the net photosynthetic rate of sorghum had little difference in different growth periods ,indicating the necessity of proper row space between sorghum and maize .Average rate of dry matter accumulation of maize and sorghum were higher in ZY4 and ZG8 pattern ,underly-ing the foundation of high yield formation .Meanwhile ,the density greatly affected spike/ear number and grain weight , but slightly affected grain number .In addition ,ZY4 and ZG8 showed better intercropping effect for jujube ,maize and sorghum .
