【摘要】 针对内蒙古实施草地禁牧舍饲的畜牧业政策及西辽河平原麦后复种收入低而不稳的实际情况 ,于2002年进行麦后复种饲料作物的研究。结果表明 :麦后复种饲料作物中 ,青贮玉米产量高、经济效益显著。与对照复种白菜相比 ,其产值超过白菜的玉米品种有5个 ,尤以金山3号效果最佳 ,其鲜草产量高达91.53t·hm -2 ,干草产量19.07t·hm -2,粗蛋白质产量1.07t·hm -2 ,每公顷产值7322元 ,比复种白菜产值增加43%。生育期、病虫害抗性、耐低温性是筛选麦后复适宜品种的重要指标更多还原

【Abstract】 The sequential cropping of forage crops after wheat was studied in the Plain of the West-Liao River Plain in2002,under the background of the policies of non grazing and low and unsteady the income on sequential cropping after wheat in Inner Mongoliˉa.The results showed:that sequential cropping of Silage corn after wheat was a planting mode with high yield and remarkably economic results.The output value of Jinshan3was7322.0$/hm 2 (The value was increased by43.0%than the Chinese Cabbage’s)with fresh forage yield of91.53t·hm -2 ,hay yield of19.07t·hm -2 and crude protein yield of1.07t·hm -2 .The growth period,the abilities of insect resistance,of disease resistance and cold-resistance were important indices.更多还原
