豆科、禾本科牧草混播栽培饲料作物的人很多,其中大部分人为了获得优质的干草或青贮,往往仅单播苜蓿,然而根据情况,禾草也是可以有效利用的。在混播草地放牧时,禾草可减少家畜患臌胀病的危险。在陡坡上部种植苜蓿时,若有禾草混杂在内,可减少侵蚀的危险。禾草在冬季很少枯死,与苜蓿混播时,苜蓿在冬季很难高出禾草,这样苜蓿也就不易枯死。
Legumes, grasses and forages have many sources of mixed-fodder crops, and most of them tend to clove alfalfa only for good quality hay or silage, but grass can also be used effectively depending on the situation. Grasses reduce the risk of swollen sickness in mixed-grass grazing. When alfalfa is planted on the steep slopes, the risk of erosion can be reduced if grass is mixed. Grass rarely dies in winter, when mixed with alfalfa, alfalfa is hard to grow above grasses in winter, so alfalfa is not easy to die.
