摘要
通过盆栽试验,研究了NPK肥和腐殖质(经腐化后的桔梗和枯草)对铅锌矿尾矿中香根草生长的影响。结果表明,添加NPK肥和腐殖质的尾矿上生长的香根草在生物量、形态性状、抗性指数、光合速率、蒸腾速率、气孔导度及水分利用效率等各项指标均比纯尾矿及仅添加NPK肥的尾矿上生长的香根草要高。研究表明NPK肥和腐殖质的综合使用提高了香根草对铅锌矿尾矿的适应性。
The paper studies the NPK fertilizer and humus（corrupted platycodon grandiflorum） affect on growth of vetiveria zizanioides in lead-zinc mine tailings though a pot experiment.The results show that vetiveria zizanioides growing on the mine tailings which are added the NPK fertilizer and humus,have the higher index than the vetiveria zizanioides both on pure tailings and on the mine tailings only added the NPK fertilizer,and these index include biomass,morphological traits,resistance index,photosynthetic rate,transpiration rate,stomatal conductance and water use efficiency other indicators.Studies have shown that the integrated utilization of NPK fertilizer and humus can increase vetiveria zizanioides adaptability of Lead-zinc mine tailings.
