生物质炭和果胶对再生水灌溉下玉米生长及养分、重金属迁移的影响
Shuitu Baochi Xuebao, 2017 利用根箱试验方法比较了生物质炭和果胶对再生水灌溉下土壤—植物系统养分和重金属迁移特征的影响及差异性。结果表明，再生水灌溉不利于植物的生长，果胶和生物质炭两个处理相比，虽然植株生长无显著差异，但果胶处理植株的生长状况优于生物质炭处理；再生水灌溉时，果胶处理地上部生物量比对照增加了59.32%。与蒸馏水灌溉相比，再生水灌溉增加了根际土壤pH；灌溉水源相同时，果胶处理根际土壤pH略低于生物质炭处理。生物质炭和果胶都增加了土壤养分的含量，果胶对土壤碱解氮、有效磷和有机质的增加效果优于生物质炭 ...

Modelling soil erosion in a small catchment on the Chinese Loess Plateau : Applying LISEM to extreme conditions [PDF]
, 2002 The Chinese Loess Plateau suffers some of the highest soil erosion rates on earth. This is caused by the fact that it can be characterized as a semi-arid area with low vegetation cover, erodible soils, steep slopes and occasional high intensity summer ...

Shuitu Baochi Xuebao, 2011 通过盆栽试验研究土壤菌对喷播基质物理性质及抗冲抗剪性能的影响。结果表明:土壤菌与黑麦草出苗率及盖度、容重、抗冲性、抗剪性4种基质效应指标之间存在着显著的相互作用关系。土壤菌的应用,明显增加土壤微生物量,基质结构基得到明显改善(基质容重降低了0.10 g/cm3),喷播植物的出苗率和盖度分别增加了55%和0.21,喷播基质抗冲抗剪能力得到改善,这既有微生物菌种对基质物理结构的改善作用,也有促进植物生长和覆盖对地表的保护作用。

Shuitu Baochi Xuebao, 2005 土壤微生物量碳、基础呼吸作用、土壤代谢商是表征土壤质量的重要指标,并且与土壤本身的理化性质有关。脱氢酶活性是土壤微生物种群及其活性的重要敏感性指标之一。通过室内培养,研究了不同铅添加水平(200~1 200 mg/kg)对青紫泥田微生物生物量碳及土壤基础呼吸作用、土壤代谢商、土壤脱氢酶的影响。研究表明:随培养时间延长,青紫泥田生物量碳呈下降趋势,基础呼吸作用随铅浓度升高而加强。土壤代谢商随培养时间延长变化趋势不同。外源铅胁迫下土壤脱氢酶活性随铅处理浓度升高明显受抑制。相关分析表明 ...
