Inhibitory Effect of Compost as Nursery Substrates on Root Rot of Anthocephalus chinensis
An experiment was conducted to study the inhibitory effect of compost from agricultural organic waste used as nursery substrates on root rot of Anthocephalus chinensis with artificial pathogen inoculation. Results showed that 13# substrate significantly reduced the occurrence of root rot, and the relative control effect of root rot reached 93. 1%. Inhibitory effect of the nursery substrate on root rot of seedlings depends on its physical and chemical role as well as rhizosphere microorganisms. Bulk density and water content of the nursery substrate are negatively correlated, while water-holding porosity and exchangeable magnesium content are positively correlated with the inhibitory effect of the nursery substrate on root rot. A positive correlation was observed between the number of rhizosphere fungi and the occurrence of root rot, while a negative correlation between the number of bacteria in the rhizosphere and the occurrence of root rot.
