摘要
对近年引进的坚尼草新品系进行了适应性试验研究 ,以筛选出适宜南方热带、亚热带的优良品系。结果表明 ,参试的 2 3个坚尼草品系 ,在本地区均能越冬 ,正常生长。其中有 8个品系的鲜草产量极显著或显著高于对照品种。产量排在前 3位的品系 :CIAT6 96 6、CIAT6 172、CIAT6 90 1,年平均鲜草产量分别为 96 795.0 kg/hm2、90 987.3kg/hm2、84 547.4 kg/hm2 ,比对照品种分别增产 6 4 .9%、55.0 %、4 4 .0 %。
Some introduced Panicum lines were evaluated to select suitable forage for tropic subtropic region in China. All 23 Pamicun lines grew well and could be over winter safely. The fresh weights of eight varieties were higher than that of the control. The average fresh yields of the first three top lines, CIAT 6966, CIAT 6172 and CIAT 6901 were 96 795.0 kg/hm 2 , 90 987.3 kg/hm 2 and 84 547.4 kg/hm 2 respectively, which were increased by 64.9% , 55.0% and 44.0% in comparison with the control.
