Shuitu Baochi Xuebao, 2003 采用萌发试验法研究了安太堡露天矿排土场土壤种子库特征,结果表明:排土场土壤中有活性种子存在,且以1年生植物为主,可为植被恢复提供物质基础;随着复垦时间的延长,土壤微环境改善,种子库的组成种类增加,数量增多,幼苗生长加快;复垦10年的沙棘、草地、刺槐林地,土壤种子库组成种类较新排土区明显增多,且优势种因复垦模式不同而异;未复垦的空旷区有利于种子传播,但土壤微环境差,不利于种子萌发,幼苗生长较差.

胶质芽孢杆菌与苜蓿根瘤菌双接种对排土场紫花苜蓿生长和土壤性质的影响
Shuitu Baochi Xuebao, 2021 为了明确胶质芽孢杆菌和苜蓿根瘤菌在矿区排土场复垦中的协同作用，以矿区排土场土壤作为基质进行盆栽试验，设置两菌单接种处理、双接种处理及对照，其中胶质芽孢杆菌和苜蓿根瘤菌用量分别为1.50%和0.25%，测定紫花苜蓿产量指标、叶片生理指标、土壤速效养分含量和土壤微生物指标。结果表明，接种胶质芽孢杆菌和苜蓿根瘤菌的各处理均能显著提高紫花苜蓿的产量指标，其中以双接种处理效果最优，将生物量和结瘤量分别比对照显著提高110.27%和124.32%；在生理指标方面，双接种处理效果低于单接种处理，未表现出协同作用 ...
