摘　　要：为了研究禾本科饲草的生产性能,试验选用20种一年生禾本科饲草材料,在黑龙江省农业科学院草业研究所试验地进行田间种植,对其生产性能进行比较分析。结果表明:高丹草Late BMR、大力士以及苏丹草的PACF8421和健宝4个品种(品系)未能完成其生育期;青贮玉米的株高最高,与其他品种差异极显著(P<0.01),苏丹草中农26837的株高最低,只有191 cm;高丹草中Enorma和Bra-sero的分蘖能力最强,单株分蘖数分别为37.00,31.50个/株,极显著高于其他品种(P<0.01);高丹草Big Kahuma的鲜草产量高,抗倒伏能力和抗病性均较强。苏丹草中Enorma的分蘖能力最强,茎叶比最小,抗病性最强。综合比较,在20种饲草品种中高丹草Big Kahuma和苏丹草Enorma宜作为黑龙江地区青饲、青贮的禾本科饲草品种。To research production performance of the gramineous forage grass,the comparison experiments for the forage crops including 20 varieties were conducted in Institute of forage and grassland Sciences,Heilongjiang Academy of Agricultural Sciences.The results showed that four varieties including Late BMR for Sorghum Hybrid Sudangrass,Hercules,PACF8421 for Sorghum sudanense（Piper） Stapf.and Jumbo could not complete their growth stage.Zea mays had the highest plant height among four gramineal forage crops,which had a significant difference（P0.01）,the plant height of variety 26827 for Sorghum sudanense（Piper） Stapf was only 191cm.The tiller ability of Enorma and Brasero for Sorghum Hybrid Sudangrass was largest,and their tillers in one unite were 37.00 and 31.50,respectively,were significantly higher（P0.01） than that of anther varieties.Out of all Sorghum bicolor×S.su-danense varieties,Big Kahuma performed best in terms of grass yield and disease resistance,Enorma for Sorghum sudanense（Piper） Stapf.performed best in terms of tillering capacity and had lower stem/leaf.Based on the integrated performance,the primary conclusion of the paper is that among those 20 varieties in four gramineous forage crops,Big Kahuma and Enorma are the best varieties for forage and silage to be extended in Heilongjiang Province.
