| Abstract: | A field rhizo-bag experiment was conducted to study the effect of microbial fertilizer,humic acid,organic-mineral complex fertilizer and ABT(grow-root powder No.4) on phosphorus utilization in rhizosphere soil at the jointing and maturity stages of maize.Results showed that the available phosphorus content and phosphorus utilization efficiency in maize rhizosphere soil increased after the application of humic acid and microbial fertilizer,and the effect was more obvious at maturity stage than at jointing st... |
