| 摘 要： | 以扁穗牛鞭草品种重高为对照,从物候期、再生速度、抗逆性、产草量、茎叶比等方面对6个扁稳牛鞭草新品系进行了农艺性状的比较试验.结果表明,种植期间各品系的再生速度、全年鲜草产量、干草产量均高于对照,抗寒、抗旱、抗病虫能力较强.从总体上看,各性状以H2003-5表现最优,其叶量丰富、抗性强、产量高,鲜草和干草产量分别比对照提高了9.38%～11.12%和20.53%43～77%,可作为优良牧草广泛推广应用.

| Abstract: | Agronomic traits comparative experiment were carried out among six new lines of whipgrass(Hemarthria compressa) in phenological period,regrowth speed,resistance,herbage yield and the ratio of stem to leaf using Chonggao as the check variety.The results indicated that the regrowth speed,fresh and dry yield of the six lines was higher than that of the check variety and the resistance of the six lines to cold,drought and pest was strong during cultivation period.Overall,the vari-ous characters of H2003-5 were ... |
