Phosphate-solubilizing microbe sin rhizosphere soils of 19 weeds in southeastern China

摘要

Low phosphorus (P) availability is one of the most important factors limiting plant growth in red soils across southeastern China. Many non-symbiotic microorganisms in rhizosphere can enhance P solubility, but little is known about the magnitude of their phosphorus-solubilizing ability (PSA) and The difference in phosphorus-solubilizing microorganisms (PSM) among plant species. The number of Phosphorus-solubilizing microorganisms and their PSA in rhizosphere soils of 19 weed species in a citrus Orchard on red soil at Changshan, Zhejiang, Chain, were investigated.
