摘  要：
为加快调整优化农业种植结构,有效解决日益突出的优质饲草料供给不足的矛盾,试验将青贮玉米新品种和秣食豆混作,以探索其混作比例对群体生物产量和饲用品质的影响。试验显示,青贮玉米和秣食豆混作在1∶2的比例下群体地上生物产量最高,群体地上生物产量亩均增产231.69kg;干物质产量亩均增加362.3kg;粗蛋白含量平均提高0.5%;粗纤维、酸性洗涤纤维和中性洗涤纤维平均降低0.06%、4.82%、5%和9.75%;产出效益平均达到1 964.15元/hm~2,平均亩产出效益多增加71.33元。其中正德305和豫青贮23在所有品种中无论是混作效果、群体地上生物产量、营养价值、饲料品质和经济效益等都表现的较为突出。结果表明,青贮玉米与秣食豆混作不仅影响群体地上生物产量,并可大幅度提高混作群体蛋白质含量和降低粗纤维、酸性洗涤纤维和中性洗涤纤维含量,提高饲料营养价值和饲用品质,实现节本增效的目的。

摘  要：
In order to speed up the adjustment and optimization of agricultural planting structure and solve the increasingly prominent contradiction between the supply and demand of high quality forage,the experiment used new varieties of corn and the soybean(Glycine max)to explore the effect of mixed cropping on yield and forage quality.The results showed that corn and soybean mixed at the ratio of 1:2 had the highest yield,the biomass was increased by 231.69 kg per mu;dry matter was increased by 362.3kg per mu;averaged crude protein content was increased by 0.5%;the contents of crude fiber,acid detergent fiber and neutral detergent fiber were decreased by 0.06%,4.82%,5% and 9.75%,respectively.The average production benefit was increased by more than 71.33RMB/mu and reached to 1964.15 RMB/mu.Among all the varieties,the 305 and 23 in Henan Zhengde silage showed distinguished performance in the effect of mixed cropping,aboveground biomass,nutritive values,feed quality and economic return.In addition,the results also showed that the mixed cropping of silage corn and soybean would not only affect the aboveground biomass yield,but also greatly improved the protein content level and reduced the level of crude fiber,acid detergent fiber and neutral detergent fiber,improved the nutritive values and feed quality,in which the cost-effectiveness could be achieved.
