摘　　要：以白三叶和全株玉米为青贮原料,设置全株玉米单贮、30%白三叶+70%全株玉米、50%白三叶+50%全株玉米、70%白三叶+30%全株玉米以及白三叶单贮共5个试验组,研究白三叶和全株玉米混合青贮的青贮效果及其最佳比例。结果表明,全株玉米单贮发酵品质良好,白三叶单贮发酵品质尚可;混贮中70%白三叶+30%全株玉米的发酵品质良好,其余为尚可;综合比较发酵品质、营养品质以及V-Score评分,得出以70%白三叶+30%全株玉米混贮发酵的品质最佳,是攀西地区开展白三叶与全株玉米混贮的最佳配比。There are Trifolium repens L. and whole corn two kinds of materials in this trial. This experiment had five treatments： whole corn single silage, 30% Trifolium repens L.＋70% whole corn, 50% Trifolium repens L.＋50% whole corn, 70% Trifolium repens L.＋30% whole corn and Trifolium repens L. single silage, it was aimed at studying the mixed silage effect of Trifolium repens L. and whole corn and finding the best mixture ratio. The results showed that the fermentation quality of whole corn single silage was well and the Trifolium repens L. single silage was passable. In mixture samples, 70% Trifolium repens L.＋30% whole corn was very good, others were passable. Through the comprehensive comparison the silage fermenta- tion quality, nutritional quality and V-Score, we could draw the following conclusions： the fermentation quality of mixed silage with 70% Trifolium repens L.＋30% whole corn was the best, and it was the best mixed silage ratio in Panxi area.
