中文摘要：

干燥物质的内容，粗略的胖、粗略的蛋白质，中立净化的纤维，酸在 43 Saccharum spontaneum L 的净化的纤维，粗略的灰， Ca 和 P。germplasms 在植物的时期期间是坚定的。在他们之中，粗略的蛋白质，粗略的胖、中立净化的纤维，净化的纤维， P 和 Ca 满足的酸被当作判定的指示物。营养的值评估与分析层次进程被执行。结果证明 A49 有最高营养的价值。它的干燥的事，粗略的蛋白质，粗略的胖、粗略的灰，中立净化的纤维，净化的纤维， Ca 和 P 满足的酸分别地是 32.35% ， 7.20% ， 4.06% ， 8.07% ， 75.81% ， 50.72% ， 0.23% 和 0.16% 。当时是有最低营养的价值。它的干燥的事，粗略的蛋白质，粗略的胖、粗略的灰，中立净化的纤维，净化的纤维， Ca 和 P 满足的酸分别地是 32.24% ， 4.62% ， 0.51% ， 6.38% ， 46.40% ， 40.02% ， 0.15% 和 0.09% 。粗略的蛋白质内容在不同 germplasms 之中显著地不同。A48 有最高粗略的蛋白质内容，并且 A14 有最低粗略的蛋白质内容。

英文摘要：

The contents of dry matter, crude fat, crude protein, neutral detergent fiber, acid detergent fiber, crude ash, Ca and P in 43 Saccharum spontaneum L. germplasms during the vegetative period were determined. Among them, the crude protein, crude fat, neutral detergent fiber, acid detergent fiber, P and Ca contents were treated as the judging indicators. The nutritional value evaluation was carried out with the analytic hierarchy process （AHP）. The results showed A49 （Guangxi） had the highest nutritional value. Its dry matter, crude protein, crude fat, crude ash, neutral detergent fiber, acid detergent fiber, Ca and P contents were 32.35%, 7.20%, 4.06%, 8.07%, 75.81%, 50.72%, 0.23% and 0.16% respectively. While A3 （Guangdong） had the lowest nutritional value. Its dry matter, crude protein, crude fat, crude ash, neutral detergent fiber, acid detergent fiber, Ca and P contents were 32.24%, 4.62%, 0.51%, 6.38%, 46.40%, 40.02%, 0.15% and 0.09% respectively. The crude protein content differed significantly among different germplasms. A48 had the highest crude protein content （9.11%）, and A14 had the lowest crude protein content （3.72%）. Based on the evaluation results, the 43 Saccharum spontaneum L. germplasms were divided into 3 groups： high-nutritional value type, moderate-nutri-tional value type and low-nutritional value type. We hoped to provide a theoretical reference for the application of Saccharum spontaneum L. as a forage grass.
