【摘要】：为探究解磷细菌与土壤酸性磷酸酶活性的关系,以解无机磷细菌P7、P19和解有机磷细菌YP17为解磷菌剂,以巨尾桉幼苗作为研究对象,以4种森林土壤为基质进行盆栽试验,设置1×106cfu·m L-1(低)、0.5×107cfu·m L-1(中)、1×107cfu·m L-1(高)3个菌浓度处理以及空白对照.结果表明:不同土壤条件下,混菌处理(P7YP17、P7P19YP17、P19YP17)对土壤酸性磷酸酶活性影响总体优于单菌(P7、P19、YP17);高浓度和中浓度处理酶的土壤酸性磷酸活性高于低浓度处理.有机解磷菌及其解磷菌群对巨尾桉根际土壤酸性磷酸酶活性的促进作用强于无机解磷菌处理.
[Abstract]:In order to investigate the relationship between phosphorus-solubilizing bacteria and soil acid phosphatase activity, inorganic phosphorus bacteria P7, P19 and organophosphorus bacteria YP17 were used as phosphorus-hydrolyzing agents, and Eucalyptus grandis seedlings were used as research objects. Pot experiments were carried out with four kinds of forest soils as substrate. The concentrations of 1 脳 106cfu 路mL 鈮，
