Introduction: Reductive soil disinfestation (RSD) is an environmentally friendly and effective approach for controlling a wide range of soil-borne pathogens. The application of organic matter is crucial for the success of RSD. Methods: In this study, We added 25 t∙ha-1 of tomato straw, bitter melon straw and pepper straw to the soil as carbon sources for RSD treatment in greenhouse soil, respectively. The soil chemical properties, enzyme activity, and microbial community were analyzed after the soil treatment and cucumber planting. In addition, the growth, development, and yield of cucumber after planting were studied. Results: The results showed that the RSD treatment increased soil pH value; SOM, AN and AK contents; and SC, UE, and CAT activities. After RSD treatment, PCoA analyses showed that the bacterial and fungal community compositions were greatly altered and that the fungal and bacterial Chao1 and Shannon indices decreased, and the relative abundance of beneficial microorganisms such as Bacillus, Arthrobacter, Streptomyces, and Penicillium increased, while the relative abundance of harmful microorganisms such as Fusarium decreased. Improtantly, the RSD treatment promoted the growth, development of cucumber and significantly increased the yield of cucumber. Based on RSD treatment effects on the soil properties and the growth and development of cucumber, pepper straw as a carbon source for RSD treatment was the most effective. Discussion: This study indicates that added vegetable straw as a carbon source for RSD treatment improved the chemical properties, enzyme activities and altered the microbial community of cucumber soil, and increased the yield of cucumber. However, the long-term effects of RSD treatments on soil properties and microbial communities need to be studied.
