Abstract: In order to verify the application effect of compound microbial inoculants in field cultivation, Amorphophallus konjac was used as the test object, and three treatments of compound microbial inoculants, chemical agents and clear water were set up to determine the growth, disease occurrence and yield indexes of Amorphophallus konjac. The results showed that compound microbial inoculants could promote the growth of stems, leaves and roots, increase root activity, reduce disease incidence, increase bulb fresh weight, promote bulb expansion and increase yield. Three chemical agents, 12% Zhongshengmycin 1 000 times dilution, 20% Thiodiazole copper 500 times dilution and 20% Thiazole zinc 500 times dilution, which were applied alternately, which could better control the occurrence of diseases, increase the yield per unit area of Amorphophallus konjac, but affect root growth and reduce root activity.
