| 摘 要： | 目的]研究蚯蚓活动对铁尾矿中植物生长的影响。方法]通过室内盆栽方法,研究蚯蚓对铁尾矿中高粱和紫花苜蓿生长的影响。结果]结果表明,蚯蚓可以改善铁尾矿中高粱和紫花苜蓿的生长,包括植物的株高、地上部和根系的生物量等,对紫花苜蓿生物量的增加作用好于对高粱的作用。同时,蚯蚓的活动可明显增加高粱和紫花苜蓿根际微生物的数量,与对照相比,细菌数量分别增加了22.7%~50.0%和90.0%~163.3%;真菌数量增加了36.8%~47.3%和8.2%~93.4%;放线菌数量增加了4.3%~52.2%和1.1%~177.8%。随着蚯蚓数量的增加,微生物数量呈现增加的趋势。结论]蚯蚓可明显促进铁尾矿中高粱和紫花苜蓿的生长,增加铁尾矿中植物根际微生物数量,利于铁尾矿中植被的恢复。

| Abstract: | Objective]The purpose of research was to study the effects of earthworm on plant grown in iron tailing.Method] The pot experiment was carried on to study the effects of earthworm on grain sorghum and alfalfa grown in iron tailing.Result] The results indicated that earthworms improved two species growth, such as plant height,fresh/dry weight of shoot and root grown in iron tailing. The items of plants above were more than those grown in iron tailing without earthworm.The microbial population in rhizospher... |
