菌剂配施有机肥下植物-土壤-微生物生态化学计量特征及内稳性——以内蒙矿区排土场中药复垦模式为例

open access: yesShuitu Baochi Xuebao, 2023
生态化学计量学是研究生态系统与多重化学元素平衡的有效方法,明确不同施肥制度对植物-土壤-微生物连续体碳、氮、磷含量及其生态化学计量比的影响,可为揭示生态系统养分循环、实现矿山复垦农业系统元素平衡及可持续发展提供参考依据。以武家塔露天煤矿排土场复垦地为研究对象,设置微生物菌剂配施不同有机肥(A1B0、A2B0、A3B0、A1B1、A2B1、A3B1) 6个施肥处理,结合苦参的种植,研究其植物-土壤-微生物碳氮磷特征及内稳性。结果表明:(1)与单施有机肥相比,有机肥配施微生物菌剂对茎叶磷 ...

干旱矿区排土场不同边坡生态修复模式下减流减沙效益

open access: yesShuitu Baochi Xuebao, 2021
为探究不同生态修复模式对露天矿区排土场边坡产流产沙规律的影响,采用野外径流小区试验方法,对矿区排土场边坡不同生态修复模式的产流产沙进行了1个雨季的连续观测。结果表明:(1)研究区降雨年内分配不均,主要集中在汛期7—9月,该时期降雨量占到年均降雨量的77.03%,是年内径流泥沙损失最多的时期。(2)不同生态修复模式与对照(只撒播灌草种子)相比均具有减流减沙效果,但是不同生态修复模式的减流减沙效益有显著差异,减流效果从大到小依次为沙柳网格模式(64.35%)>生态棒模式(56.56%)>生态袋模式(52 ...
