摘要： 对不同生育期青贮玉米(Zea mays L.)品种之间以及青贮玉米和豆科牧草混播对产草量及品质的影响进行研究,试验以中原单32、海育9号和高值扁豆(Dolichos lab L.cv.Highworth)为材料,设3个不同混播比例,即中原单32和海育9号、中原单32和高值扁豆均以1:1,1:2和2:1比例进行混种混收试验。结果表明:在黑龙江省北部积温较低地区,中晚熟玉米和早熟玉米以2:1比例混播,鲜草产量和可溶性总糖(WSC)含量最高;以1:2比例混播,营养品质最好。在黑龙江省西部和中南部积温较高地区,青贮玉米和豆科牧草以1:2比例混播时,鲜草产量最高,营养品质最好。

Abstract: Forage yield and quality were investigated between different stages of corn silage as well as corn silage and mixture sowing legume.Zhongyuandan 32,Haiyu 9 and Highworth dolichos were used as forage crops in this experiment.The mixture sowing proportion was 1:1,1:2 and 2:1.Results showed that the mixture sowing of late-maturing and early-maturing varieties(2:1) could improve fresh yield and soluble sugar content of forage at accumulated temperature area of northwest Heilongjiang Province.The mixture sowing of silage corn(Zea mays L.) and leguminous forage(Dolichos lab L.cv.Highworth)(1:2) could improve the fresh yield and quality of forage crop at higher accumulated temperature regions of both west and mid-south Heilongjiang Province.

Key words: Silage corn, Dolichos lab L.cv.Highworth, Mixture planting proportion, Yield, Quality
