摘　　要：对8个多花黑麦草品种从生育期、产草量、茎叶比等方面进行了比较研究,结果表明:特高多花黑麦草产量最高,其干物质产量为19 397 kg/hm2;蓝天堂产量次之,其干物质产量为18 242 kg/hm2;特优多花黑麦草产量最低,其干物质产量为14 770 kg/hm2。从总体上来看,各个品种之间产量有一定的差异,但是产量差异不显著。Eight introduced Italian ryegrass varieties were studied in their growth grass yield, ratio of stem and leaf and so on. The result showed that the yield of “Tetragold” was the highest, its dry matter is 19 397 kg/hm^2; “Blue heaven brand” took the second place, its dry matter was 18 242 kg/ hm^2 . The yield of “teyou” was the lowest, its dry matter was 14 770 kg/ hm^2. On the whole , there was some difference in the yield of different varieties, but the difference was not so significant.
