Role of rhizosphere microorganisms in growth of plants in soils with low P availability

低磷土壤中根际微生物对植物生长的影响与植物和土壤生物的需求相比，澳大利亚许多土壤中的有效磷浓度较低。植物在低磷条件下生长的能力不同，但根际微生物在植物从低磷土壤中吸收磷的作用在很大程度上是未知的。我们将确定根际微生物在不同作物基因型和本地植物物种、不同磷有效性的澳大利亚土壤中对磷的溶解和动员的作用。研究结果将全面揭示根际微生物生态在作物和本地植物磷吸收中的作用。

Role of rhizosphere microorganisms in growth of plants in soils with low P availability. The concentration of available phosphorus in many Australian soils is low compared to the requirement of plants and soil organisms. Plant genotypes differ in their capacity to grow at low P availability but the role of rhizosphere microorganisms in plant P uptake from such soils is largely unknown. We will determine the role of rhizosphere microorganisms in P solubilisation and mobilisation in different crop genotypes and native plant species in different Australian soils with low P availability. The results will give a comprehensive picture of the role of rhizosphere microbial ecology in phosphorus acquisition by crop and native plants.
