摘　　要：通过对上茬春小麦进行品种产量比较,下茬复种不同品种鲜食玉米、萝卜、白菜,从中确定能够充分利用沈阳地区的农业气候资源的高产优质高效种植模式的复种作物品种组合。试验结果表明,春小麦品种辽春9号和沈春498较抗旱,产量突出;鲜食玉米品种富粘1号和垦粘1号较好,熟期适宜,成熟性好;白菜品种秋冠和世秋产量表现好;萝卜品种白秋美浓、春雷和红丰2号产量较高,有种植前景。Multiple cropping system with wheat as a preceding crop has proven to be an available approach to enhance the land use efficiency.In this study,different spring wheat varieties were compared,the yields of succeeding crops,such as corns on the cob,radishes and Chinese cabbages were evaluated,and finally,the optimal double cropping patterns which could fully use agricultural climatic resources of Shenyang area were illustrated.The results showed that the preceding spring wheat varieties,Liaochun 9 and Shenchun 498,produced higher yield than others;corn on the cob varieties,Funian 1 and Kennian 1 performed better than others;Chinese cabbage varieties Qiuguan and Shiqiu had higher yields;radish variety Baiqiumeinong,Chunlei and Hongfeng 2 were high-yielding and expected to be promising in the multiple cropping system.
