摘要
对玉米／燕麦、玉米／箭舌豌豆、玉米／燕麦和箭舌豌豆立体种植模式的产出效果进行了研究。结果表明，套种牧草使玉米籽实产量较对照有显著降低，但总生物产量并没有降低，且粗蛋白质产量显著高于对照，经济效益和能量转化效率都有所提高。从生产饲料的角度，经模糊综合评价，得到景泰荒漠绿洲区最佳玉米牧草立体种植模式为：燕麦与箭舌豌豆混播与玉米套种，带幅１５０ｃｍ。
The effect of output of intercropping sown mixed maize with oat, maize with vetch and maize and oat and vetch was studied. The result showed that the yield of maize seeds significantly decreased over control, however, the tolal biomass did not decrease, and yield of crude protein significantly higher than control, economic efficiency and energy changing efficiency increased. From the view of fodder production and analysis of fuzzy, the optimum model in Jingtai Desert Oasis area was oat mixed sowing with vetch and intercropping with maize, and 150 cm between rows.
