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 comparing the planting experiments, the effects of coastal saline land on coastal fertility of four introduced grass species Hua Nan, Gui Mu, N51 and So Mu were analyzed. The results showed that tiller number, total leaf number and leaf number (P <0.05). The diameter and yield of fresh grass were significantly different from those of N51 and Guimu (P <0.05), but the difference of stem and leaf of the four cultivars was not significant Therefore, Su Mu grass can be planted in Jiangsu coastal beach saline land.
