“小黑麦+青贮玉米”牛羊饲草生产模式研究

2007—2008年,经过小黑麦复播青贮玉米田间试验,初步探讨了山西省北部农区新型牛羊饲草生产模式的可行性。结果表明,12个小黑麦品种均超过鲜草产量37 500 kg/hm2、干草产量9 000 kg/hm2的设计指标,品种间鲜草产量差异不显著、干草产量差异显著;2个玉米品种青贮产量差异不显著,产量指标未能达到75 000 kg/hm2目标要求。对该生产模式进行经济效益估算,结果表明",小黑麦+青贮玉米"一年两作年纯利润为12 765元/hm2,比一年一作玉米生产增收1 500元/hm2,是山西北部农区值得推广的生产模式。

Research about Cattle and Sheep Forage Grass Production Model of "Triticale + Silage-corn"

After triticale composite seeded silage corn field trials, cattle and sheep forage grass new production model feasi-bility at the agricultural area in north Shanxi Province was studied from 2007 to 2008. The result indicated that 12 triticale vari-eties fresh grass yield showed no difference,but the hay output difference was remarkable. All of the 12 triticale varieties of the fresh grass production surpassed design target 37 500 kg/hm~2 and the hay output surpassed design target 9 000 kg/hm~2. Two corn variety silage output difference was not remarkable, the production did not reach goal of 75 000 kg/hm2. The economic efficiency estimate was carried on to this production model and the results indicated that "triticale + silage corn" two crops one year can make net profit of 12 765 Yuan/hm~2·year. As the corn production increased 1 500 Yuan net incomes, this production model is worth to be promoted in agriculture area in north of Shanxi Province.
