摘　　要：以单作糯玉米和单作蔬菜为对照,探讨了蔬菜间、套作糯玉米体系下作物干物质积累和产量差异。结果表明,间、套作糯玉米一直处于优势位,干重显著高于单作糯玉米,具有间、套作增产优势;间作青刀豆产量较单作低,造成间作体系减产;套作西兰花前期植株小、结球晚,后期加快生育进程,产量与同期单作西兰花相比无明显差异,套作体系增产10.93%～11.57%。Dry matter accumulation and yield of glutinous maize/vegetables in relay-intercropping system were studied,compared with sole cropping of glutinous maize and sole cropping of vegetables.The result indicated that there was obvious advantage on glutinous maize under relay-intercropping and dry matters were significantly higher than the sole cropping of glutinous maize.The intercropping system of maize and green string bean had a lower yield because the yield of intercropping of green string bean was lower than the sole cropping of green string bean.The growth of the relay-intercropping broccoli was slower and it flowered later at the earlier development stage,but was accelerated at the later stage,so there was no significant difference between the sole cropping of broccoli and the relay-intercropping in yield.The yield of glutinous maize/broccoli relay-intercropping system increased by 10.93%-11.57%.
