An effective and moreenvironmentally safe method than pesticides is needed for its control. Theefficacy of B. cellarum control, growth of Chinese chive and soil microbialdiversity were investigated after uae of soil solarization to exterminate thisinsect pest. The results show that on the first day after soil solarization 100%control of B. cellarum was achieved. Growth of Chinese chive was lower insolarized plots than in control plots over the first 10 days after treatment. Chivegrowth in solarized plots increased subsequently to match that in the controlplots. Moreover, the soil microbial community diversity in the treatment groupdecreased initially before gradually recovering. In addition, the abundance ofbeneficial microorganisms in the genus Bacillus and the phyla Proteobacteria,Chloroflexi and Firmicutes increased significantly. Soil solarization is thereforepractical and worthy of promotion in Chinese chive-growing regions.展开更多
