摘要
丹江口水库大坝增高后,水库库滨存在大面积新淹没农田,面临着营养盐释放的风险。通过室内模拟淹没实验的方式,对香根草、狗牙根、野艾蒿三种植物在淹水状态下的生长状况及对土壤中氮磷营养盐释放的抑制效果进行研究。结果表明,在长期淹水的条件下,三种植物对土壤硝态氮的释放具有非常显著的抑制作用,但对于铵态氮和总磷释放的抑制效果不明显。香根草对硝态氮释放的抑制能力最强,野艾蒿和狗牙根相对较弱。
After the heightening of Dangjiangkou reservior dam,large area of agricultural land in the shoreland may face the risk of soil nutrient release. The inhibitory effect on nitrogen and phosphrus release of three species of plants(Vetiveria, Cynodon and Artemisia) was studied through indoor simulated experiment. The results showed that in the long-term flooding condition, the three plants showed a significant inhibitory effect on the release of nitrate nitrogen, but the inhibitory effect on ammonia and total phosphrus were not significant. Vetiveria show the highest inhibiton effect on the nitrate nitrogen, while the inhibiton effect of Cynodon and Artemisia were relatively low.
