Effects of Different Mixture Sowing on Yield and Quality of Forage Crop

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.
