Abstract: In order to reduce the amount of peat and broaden the way of resource utilization of green waste,22 formulas were compounded with green waste compost,peat,coarse sand and perlite according to different volume ratio to screen the matrix formula of Hibiscus rosa-sinensis cutting seedling in high temperature period in summer.The results showed that when the proportion of green waste compost in the substrate was 10%-30%,the cutting survival rate and rooting effect of Hibiscus rosa-sinensis in high temperature period were significantly improved,and the best substrate formula was V greennery waste∶V peat∶V perlite=1∶5∶4（T9）,which could be used in Hibiscus rosa-sinensis seedling production in high temperature period of summer.
