摘　　要：山西中部地区小麦套种青贮玉米种植模式比传统单一种植小麦、玉米更容易实现增产增收。在该种植模式下,选择山西省审定的水旱兼用小麦新品种长麦251作为小麦配套品种,在小麦产量得以保证的前提下,青贮玉米品种的选择以及适宜的套种种植密度和播期是实现小麦玉米双增产的关键因素。试验结果显示,大京九26在所有参试青贮玉米品种中产量位居第1,是比较适合小麦套种的青贮玉米品种;大京九26在该套种模式下的最佳种植密度是75000株/hm^(2),其最佳播期5月22日。In the central part of Shanxi Province,the wheat interplanting silage corn mode is easier to implement increase production than traditional single planting wheat and corn.Under this mode,Shanxi Province authorized variety Changmai 251 was selected as a interplanting variety,which was a new wheat variety used both in irrigated land and dry land.Under the premise that the wheat yield was guaranteed,silage corn varieties of choice and the suitable planting density and sowing date was the key factor to realize wheat and corn both increase.Test results showed that Dajingjiu 26 ranked the first among all the silage corn varieties,which was a silage corn variety suitable for wheat intercropping.Under this interplanting mode,the optimal planting density of Dajingjiu 26 was 75000 plants/hm^(2);the best sowing date was May 22.
