Effects of inoculation of Fritillaria Taipaiensis P.Y.Li with growth-promoting bacteria on inorganic elements in rhizosphere soil

Abstract

We collected bulbs and soils of Fritillaria Taipaiensis P.Y.Li inoculated with 5 different growth-promoting bacteria to analyz the content and change rules of 10 inorganic elements in Fritillaria Taipaiensis P.Y.Li and soils, revealing the effects of inoculation with different growth-promoting bacteria. The results showed that the inoculation of beneficial microorganisms from the exogenous can regulate (promote) the infection intensity of AM fungi in the roots of Fritillaria Taipaiensis P.Y.Li. Hg and As elements were not detected both in rhizomes and soil, and all other 8 inorganic elements were detected. There were significant differences(P<0.05) in the contents of the remaining 8 inorganic elements, and the the content of K and Ca in the bulb of the Cc treatment group reached 3 times than the rhizosphere soil, and the biggest difference between Mn and Zn reached nearly 5 times. The analysis of the enrichment coefficient showed that the K, Ca, and Mg in the bulbs tended to be higher than those in the soil; the trace elements Mn, and Zn also tended to be higher than the soil; the harmful elements Cu, Pb, and Cd were lower than the soil. The metal elements in the rhizosphere soil were low and in the unpolluted range. Correlation analysis showed that there are synergistic and antagonistic effects among medicinal materials, rhizosphere soil, medicinal materials and rhizosphere soil elements.
