紫花苜蓿与全株玉米裹包混合青贮试验研究

Study on Mixed Silage of Alfalfa and Whole Plant Corn

摘要:

本试验研究了苜蓿和全株玉米混合青贮时的最佳混合比例。试验设苜蓿单贮组、玉米单贮组，及苜蓿与全株米玉比例分别为25∶75、33∶67、40∶60、50∶50、60∶40、67∶33、75∶25的混合青贮组7个,共9个处理组。结果表明：与苜蓿单贮相比，混合青贮能有效提高青贮饲料的发酵品质，但营养品质降低。所有混合青贮处理中，苜蓿与全株米玉比例为60∶40、67∶33、75∶25组的混合青贮饲料发酵品质较好，这三个组中混合比例为60∶40的混合青贮饲料相对饲用最高，可在生产中推广应用。

Abstract:

This experiment studies the optimal mixing ratio of alfalfa and whole corn for silage. The test set alfalfa singlestorage group, corn singlestorage group, and the ratio of alfalfa to whole plant rice and corn were 25∶75, 33∶67, 40∶60, 50∶50, 60∶40, 67∶33, 75∶25 respectively. There are 7 mixed silage groups. These are a total of 9 treatment groups. The results showed that compared with alfalfa single storage, mixed silage could effectively improve the fermentation quality of silage, but the nutritional quality was lower. Among all the mixed silage treatments, the fermentation quality of the mixed silage in the groups with the ratio of alfalfa to whole plant rice corn at 60∶40, 67∶33, and 75∶25 was better. Among the three groups, the mixed silage with a mixing ratio of 60∶40 had the highest relative feeding and could be popularized and applied in production.
