山西中部小麦青贮玉米一年两作种植模式研究

Study on Two Crops Modes of Winter Wheat and Silage Corn in Central Shanxi Province

与小麦蔬菜或大豆等一年两作的传统种植模式相比,小麦青贮玉米一年两作更容易增产增收。收集了14个青贮玉米品种进行套种和复播2种不同种植模式试验。初步筛选出适宜在山西中部与小麦套种的青贮玉米品种有豫青贮23和金岭青贮10;适宜在小麦收割后复播青贮玉米品种有豫青贮23和金岭青贮67;套种模式比复播模式更易获得高产。该研究为山西中部小麦青贮玉米植模式提供理论基础,为农民种植多样性和增产增收提供指导。

Comparison with the double-crop traditional planting mode of wheat, vegetables or soybean, the double-crop wheat and silage corn can better increase production and income. A total of 14 silage corn varieties were collected, and two planting modes of interplanting and multiple seeding were carried out. We found that Yuqingzhu 23 and Jinlingqingzhu 10 were suitable for interplanting with winter wheat;Yuqingzhu 23 and Jinlingqingzhu 67 were suitable for multiple seeding after the harvest of wheat;interplanting mode was easier to obtain high yield than the mode of multiple seeding. This research provided theoretical basis for wheat and silage corn planting mode in central Shanxi Province, and offered guidances for the planting diversity and the income and yield increase of farmers.
