摘要

选取小叶锦鸡儿、山杏、杨树和差巴嘎蒿4种典型人工固沙群落为研究对象

以半流动沙丘为对照

对土壤养分含量、微生物量和主要酶的活性进行了对比研究。结果表明

4种固沙植物均能明显改善土壤C、N、P、K和微生物量C、N含量

提高土壤水解酶和氧化还原酶的活性

尤其是对土壤表层0-10 cm的改良效果更加明显。其中小叶锦鸡儿群落0-30 cm土层内微生物量C、N含量、脲酶、磷酸单酯酶、蔗糖酶、蛋白酶、脱氢酶和硝酸还原酶的活性以及有机质、N、P、K等养分含量明显高于其它3种植物群落

表现出强大的改善沙土环境的能力

可在沙化土地植被建设中大面积应用。土壤微生物量C、N分别与有机质和全N以及与各种土壤酶活性之间均存在显著的正相关性。
