Abstract:The differences of microbial diversity in rhizosphere soil of cucumber in greenhouse were stud -ied under welsh onion-cucumber rotation and continuous cucumber cropping modes .On this basis , the influ-ences of welsh onion root exudates on soil microbial diversity were further discussed .The results showed that , compared with continuous cropping , welsh onion rotation increased the diversity and evenness indexes of bac -teria and actinomyces and reduced those of fungi in cucumber rhizosphere soil .The welsh onion root exudates treatment could increase the diversity and evenness indexes of bacteria and fungi in cucumber rhizosphere soil , but the effect on actinomyces was not obvious .High levels of welsh onion root exudates could cause aggrega-tion of some bacteria and fungi in cucumber rhizosphere soil .
