摘要:
丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF)和膨润土都能影响植物的生长和对重金属的吸收。以铅锌矿区周边污染农田土为供试土壤,开展室内盆栽试验,研究接种AMF、施膨润土的单独和复合处理对蚕豆生长和重金属累积的影响。结果表明:接种AMF、施膨润土、AMF+膨润土复合处理都增加蚕豆叶片光合色素含量、株高和生物量,降低土壤有效态重金属含量,减少植株地上部和地下部重金属含量,但增加蚕豆地上部重金属的累积量。AMF+膨润土复合处理下,蚕豆叶片光合色素(叶绿素a、叶绿素b和类胡萝卜素)含量和植株生物量最大,土壤有效态重金属含量和植株重金属含量最低。双因素方差分析表明,接种AMF、施膨润土对土壤重金属有效态含量、蚕豆生长(叶片光合色素含量、株高、生物量)、植株重金属含量与累积量存在显著或极显著的影响,但接种AMF与施膨润土处理间没有显著的交互作用。表明重金属胁迫下,接种AMF和施膨润土单独处理都能促进蚕豆生长和降低植株重金属含量,但复合处理没有叠加效应。
Abstract:
Both the arbuscular mycorrhizal fungi (AMF) and bentonite and affect the plant growth and absorption of heavy metals. This paper aimed to study the effects of the individual and combined treatments of AMF and bentonite on the growth and heavy metals accumulation in the faba bean. A pot experiment was conducted using the heavy metals polluted soil around a lead-zinc mining area in Yunnan Province. The individual and combined treatments of AMF and bentonite increased the?photosynthetic pigments content in leaves, height and?biomass of the faba bean, reduced the content of available heavy metals in soils, and decreased the heavy metals content in the aboveground and underground plant, but increased the heavy metals accumulation in the aboveground plant. A highest content of photosynthetic pigment (chlorophyll a, chlorophyll b and carotenoid) in leaves and a maximum biomass of the faba bean, minimum content of available heavy metals in soils and plants were observed in the combined treatment of AMF and bentonite. According to the?two-way?ANOVA analysis, both the AMF and bentonite had significant or very significant effects on the content of available heavy metals, growth (photosynthetic pigment content, height and biomass), heavy metals content and accumulation in the faba bean. However, there were no significant interactions between the AMF and bentonite. Results indicated that both the AMF and bentonite enhanced the growth and decreased the heavy metals content in the faba bean, but there was no a superposed effect in the combined treatment.
