Abstract Under sunlight greenhouse cultivation，we study the effect of composted tsugae bark and composted corn straw on tomato（Ｌycopersicon esculentum Mill.）growth，yield，root-knot nematode disease incidence and soil microbes．The results indicate that composted tsugae bark and corn straw are effective，to some extent，against tomato root-knot nematode disease，and the mixture of composted tsugae bark and corn straw has the best effect．Meanwhile，the use of various compost can increase tomato biomass and the amount of soil microbes．By pertinence analysis we conclude that there exists negative correlation between root-knot nematode number and microbe amount. This indicates that microbe variety has control effect on root-knot nematode.
