摘要
对松嫩平原盐碱化草地几种常见牧草体内Ｋ＋、Ｎａ＋、Ｃａ２＋、Ｍｇ２＋等无机离子和有机溶质脯氨酸、柠檬酸、甜菜碱的含量进行了测定．结果表明，不同牧草在这些物质合成和积累能力上存在明显差异，它们是通过不同代谢途径和机理来适应盐碱环境的．
The contents of inorganic solutes including K +、Na +、Ca 2+ 、Mg 2+ and orgahic solutes including proline and beet alkali in several common forages grown on Songnen plain were surveyed. The results showed that the forages significantly varied in the synthesizing and accumulating ability for the above substances. They adapt to saline-alkali environment through different ways and mechanisms.
