| 摘 要： | 对一年生黑麦草A2003与对照品种原始群体(CK1)和贵草1号(CK2)在贵州南部独山地区进行生育期、生长速度、茎叶比、鲜草产量、营养价值等指标观察测定,结果表明:一年生黑麦草A2003主要生产性能均高于对照品种.其中:鲜草产量平均为4719kg/667m2,种子产量平均为54kg/667m2.鲜草产量及种子产量分别比对照品种原始群体(CK1)和贵草1号(CK2)增产10%以上;但营养价值比贵草1号(CK2)低0.29%.

| Abstract: | Three ryegrass lines or variety,A2003,the original population(CK1) and Guicao 1(CK2) were tested to evaluate their growth period,growing speed,ratio of stem to leaf,fresh grass yield and its nutrient value in Dushan county.The results showed that the average fresh grass and seed yield were 4 719 kg/667m2and 54 kg/667m2,19.6% and 12.3%,11.3% and 10.3% higher than CK1 and CK2 respectively,but its nutrient value was 0.29% lower than CK2. |
