| 摘 要： | 比较三种耐盐牧草生物修复盐渍化耕地效果得出：各处理较对照在0-90cm土层范围内土壤含盐量降低了12.30％-19.86％。牧草植株不同品种、不同生育期内对K^＋、Na^＋的选择吸收能力存在差异，主要表现在：沙打旺苗期植株K^＋、Na^＋含量最高但收获期降至最低；碱茅草和小黑麦收获期的K^＋含量保持在较高水平，且Na^＋含量比苗期均有增加；苗期和收获期Sk/na值均以小黑麦最高，沙打旺居中，碱茅草最低；通过收获植株地上部秸秆Na^＋移出量分别为：小黑麦：38.03kg／hm^2，沙打旺：13.68kg／hm^2，碱茅草：13.24kg／hm^2，种植小黑麦修复盐渍化耕地效果最佳。

| Abstract: | Comparative experiment of there kinds of forage remediating Salt alkali Farmland was carried out.The results showed that salt content can be reduced from 12.30% to 19.86% of the 0-90cm soil layers,The capacity of choice absorbing for K ,Na exists differences during growing period and species of the forage: In seedling period two ion express highest but lowest at harvest for A.pall;Yet P.spp.and Tricale be concluded:K content remaining higher level while Na was increasing than before.The SK/Na value of tricale is higher than A.pall.and aslo P.spp.Na can be take away from farmland through havest Straw stalk as this: Tricale:38.03Kg/hm2;A.pall:13.68 Kg/hm2;P.spp:13.24 Kg/hm2.Growing Tricale is the best choice to remediate saline-alkali Farmland. |
