5种禾本科牧草草产量及营养品质比较

2002年5月~9月在内蒙古西辽河平原水浇地条件下进行了不同刈割方式下5种禾本科牧草的草产量及营养品质的比较研究。结果表明，鲜草草产量健宝、苏波丹二次刈割高于一次刈割，甜格雷兹、润宝、大力士一次刈割高于二次刈割； 各品种干草草产量均以一次刈割高于二次刈割；受粗蛋白质含量的影响，粗蛋白质产量健宝、苏波丹、大力士二次刈割高于一次刈割，甜格雷兹、润宝、一次刈割高于二次刈割，综合产量及品质认为，健宝、苏波丹以二次刈割青饲喂利用为宜，甜格雷兹、润宝以一次刈割青贮利用较佳。

Comparison on Yield and Quality of 5 Grass family forage varities

The comparison on the yields and qualities of 5 vsrities of grass family forage was conducted two clipping ways in irrigated fields in Xiliaohe plain in inner Mongolia,from May to Sepember,2002.The results showed,The fodder yield of Jumbo and Superdan clipped twice was higher than those of once especcticely.However,Sugargraze,Runbao and Dalishi is opposite.In yield of hay ,All of them that were cilpped once are higher than that of twice.As the affect of crude protein content,Jumbo, Superdan and Dalishi that was clipped twice is higher than once in yield of crude protein.However,Sugargraze ,Runbao are opposite.Considered yields and qualities with twice clipping fit green chop while Jumbo and Superdan ,Runbao fit silage.
