摘要 通过比较种植试验,分析了江苏沿海滩涂盐碱地对4种引进的象草品种华南、桂牧、N51以及苏牧生育性状的影响,结果表明:滩涂盐碱地种植苏牧象草的分蘖数、总叶片数和叶长明显高于其余3种象草(P<0.05),苏牧象草的直径、鲜草产量与N51、桂牧差异显著(P<0.05);而4个品种象草的茎叶比差异不显著,因此,苏牧象草可在江苏沿海滩涂盐碱地上推广种植。 By comparative planting test, we analyzed the growth characters of four introduced grassiness varieties ( Huanan, Guimu, N51 and Sumu) planted in the coastal intertidal saline - alkali land in Jiangsu. The results showed that Sumu planted in in- tertidal saline - alkali land had significantly more tiller number, total leaf number and leaf length than the other three varieties ( P 〈 0.05 ) , and the stem diameter and fresh grass yield of Sumu grassiness were significantly different from those of the other two varie- ties except for Huanan ( P 〈 0.05 ). There was no significant difference in stem - leaf ratio among these four varieties. Therefore, Sumu grassiness can be popularized and planted in the coastal intertidal saline - alkali land in Jiangsu.
