代表性成果

--冻融对湿地土壤—植物的遗留效应

揭示了冻融过程→土壤反硝化→植物生长的级联机制,为春季湿地植物较其它生态系统返青晚提供了一种新的解释。



--植物种内基因型多样性降低土壤生物群对植物生长的抑制作用

植物基因型多样性在稳定生态系统功能,提高系统生产力等方面具有重要作用。本研究通过温室控制实验,对土壤生物群是否影响基因型多样性与系统生产力之间的关系开展研究,结果表明土壤生物群对植物生长的负效应,随植物种内基因型多样性的增加而显著降低,该结果首次证实土壤生物群在影响基因型多样性与生态系统生产力之间关系中具有重要意义,为基因型多样性提高系统生产力机制研究提供了全新的思路。



--盐度影响人工结皮微生物组成和功能:对修复盐渍化土壤的启示

接种蓝藻构建人工结皮是一种极具应用前景的退化土壤生态修复方式。为了探究不同蓝藻对盐分的耐受能力,筛选对盐渍化土壤具有较强耐受性的蓝藻,本研究对盐胁迫下人工结皮的群落结构变化进行了研究。结果发现,不同蓝藻对盐分的敏感程度及耐受性存在明显差。人工结皮在接种后18年内,都是以Microcoleus vaginatus 和Scytonema javanicum占优势,而在1%的盐份胁迫下,这两种的相对丰度均显著下降。相较之下,更高的M. steenstrupii 、 Phormidium sp.基因拷贝数及相对丰度被检测到。本研究证实了结皮蓝藻的盐分偏好性,可为筛选盐渍化土壤生态修复的优良藻株提供重要参考。


--植物生长繁殖对土壤生物与非生物因素的反馈调节

揭示了樱桃番茄在土壤养分、土壤丛枝菌根真菌、土壤线虫综合作用下的生长繁殖策略。发现植物根系在面临线虫取食的压力下,将更多的氮和磷分配给地下根系。该过程不仅有利于满足根系功能的维持,更重要的是促进菌根定殖和提高根系抵抗线虫侵害的能力。验证了土壤养分调控下,植物可能通过改变其体内的养分分布来更好的适应土壤环境的变化,并且其养分的分配格局受到土壤和生物因素的综合影响。


--微藻阴极燃料电池产生物电协同强化去除噻虫啉

THI(10、20和50 mg/L)。结果表明,与开路条件相比,生物电(闭路)的产生可使THI的去除率显著提高13.14–32.47%。中低浓度噻虫啉(10、20mg/L)对小球藻的生物量并无明显影响;最高的噻虫啉去除率与生物电压的产生(202 mV)均发生在低浓度10mg/L组。另外,在整个降解过程中共检测到7种代谢产物,其毒性均显著低于母体噻虫啉。本研究结果证实,微藻燃料电池在协同生物电产能、高效去除新烟碱类农药方面具有良好的应用前景。
