Many studies have been conducted on the effects of biochar(BIC)or garden waste compost(GWC)on the growth of greenhouse vegetables. However, few reports have been focused on the combined effects of two types of materials. In this study, the combined effects of BIC and GWC at different ratios on soil physical and chemical properties and Chinese cabbage yields were studied in a field experiment. Results showed that:(1)Both BIC and GWC significantly reduced soil bulk density by 2.86%~10.71%, but increased CEC, ...
