Project description:Microbes play key roles in diverse biogeochemical processes including nutrient cycling. However, responses of soil microbial community at the functional gene level to long-term fertilization, especially integrated fertilization (chemical combined with organic fertilization) remain unclear. Here we used microarray-based GeoChip techniques to explore the shifts of soil microbial functional community in a nutrient-poor paddy soil with long-term (21 years).The long-term fertilization experiment site (set up in 1990) was located in Taoyuan agro-ecosystem research station (28°55’N, 111°27’E), Chinese Academy of Sciences, Hunan Province, China, with a double-cropped rice system. fertilization at various regimes.
Project description:Pteris cretica L var. nervosa is one of the dominent fern species at antimony mining area where arbuscular mycorrhizal fungi can be found as a symbiosis. The effect of AMF on fern exposed to long-term excessive Sb was pooly understood. The project applied this fern co-cultivting with or withour AMF under different concentration of Sb in soil for charicterising Sb phytomediation ability of it along with the effect by AMF symbiosis.
