Application of Gas Chromatography-Ion Mobility Spectroscopy for Honey Quality Evaluation [PDF]

Honey is rich in nutrients and has a wide range of biological activities. However, due to the different botanical origins, geographical origins, entomological origins, and maturity, honey shows significant differences in their endogenous compositions and

黑曲霉对潮褐土镉、锌污染的原位固定修复潜力研究

Shuitu Baochi Xuebao, 2011
采用温室盆栽试验,研究了在黑曲霉(30582)作用下油菜对潮褐土Cd、Zn复合污染胁迫的耐性及富集特征。结果表明:接入黑曲霉菌液对油菜地上部干重总体上无明显影响,且降低了油菜对土壤Cd、Zn的吸收量。加入黑曲霉菌液后,油菜地上部和地下部Cd含量较对照最高分别降低了31.60%,37.82%;地上部和地下部Zn含量较对照处理最高分别降低了35.12%,35.74%;土壤有效态Cd、Zn含量显著减少,较对照最高分别降低了30.51%,39.64%。综上,黑曲霉有效地降低了污染土壤中Cd、Zn的生物有效性 ...

铅-锌-镉复合污染物在土壤-芥菜/油菜系统中的迁移及交互作用

Shuitu Baochi Xuebao, 2007
了解重金属复合污染物在土壤-植物系统中的迁移分配情况对污染土壤的安全利用、土壤环境质量标准的修订以及重金属污染土壤的植物修复具有重要意义。通过盆栽试验,以芥菜和油菜为例,研究了铅-锌-镉复合污染物在土壤-植物系统中的迁移分配情况。结果表明:与对照相比,复合污染条件下,芥菜和油菜体内重金属含量显著提高,且Cd含量的提高程度要远远高于Pb和Zn;芥菜和油菜对Cd的吸收达到了100 m g/kg以上,表现出超富集植物的吸收水平。重金属的富集系数大小依次为Cd>Zn>Pb,地下部富集系数要高于地上部 ...

化肥减量配施生物有机肥对油菜生长及土壤微生物和酶活性影响

Shuitu Baochi Xuebao, 2018
通过盆栽试验，研究化肥减量10%～30%条件下，配施与所减化肥相同用量的2种生物有机肥对油菜生理代谢、产量、土壤生物学特性和养分含量的影响，系统的阐述了生物有机肥应用于蔬菜生产的优势所在。结果表明：减量化肥配施生物有机肥可促进油菜生长，提高油菜叶片内叶绿素含量和根系活力，同时增强了油菜叶片和根系内抗氧化酶（SOD、POD、CAT）活性，降低了过氧化物质含量（MDA、O2?
