宁南山区不同引进饲草青贮品质评价

为了解决宁南山区冬季牧草缺乏、优质饲草种类单一的现状,对宁南山区引进的2个玉米品种（金刚50、屯玉168）、5个禾草品种（大力士甜高粱、固原草高粱、籽粒苋、丹燕444、冬牧70苜蓿）进行了青贮试验,并对其青贮品质及营养成分进行了测定,旨在为该地区饲草的进一步利用提供试验依据。结果表明,7个饲草品种均可以单独青贮成功,但籽粒苋和冬牧70苜蓿单贮效果不理想,可适当混贮以提高其品质。

Quality Assessment of Silage Prepared with Introduced Forage in Ningnan Mountain Area

In order to alleviate the status of lacking pasture in winter and limited available varieties of high quality forage in Ningnan mountain area and to provide scientific basis for the forage utilization in this region, a silage preparation experiment was conducted with two maize varieties （Jingang No.50 and Tnyu No.168） and five gramineous forage varieties （Dalishi sweet sorghum, Guyuan forage sorghum, grain amaranth, Danyan 444, Dongmu 70 alfalfa）. The quality and nutritional value of the silage prepared with different varieties of forage was determined. The results showed that silage could be successfully prepared with every single forage variety of the seven tested forage varieties, while poor quality was observed in silage singlely prepared with grain amaranth or Dongmu 70 alfalfa, indicating the necessity of the appropriately mixed use of these two forage varieties.
