[Objective]In order to provide reference for the application of the new type of biochar based fertilizer in facility agriculture,espe-cially in the production and cultivation of green vegetables.[Method]We selected the greenhouse vegetables which have been cultivated for a long time as the object,through the combination of indoor culture and field experiment,and studied the water retention of the new type of bio-char based fertilizer,and its impact on the yield,commodity and soil physicochemical properties of protected green vegetables.[Result]The results show that the new biochar based fertilizer can reduce soil bulk density and improve soil water-retaining property and organic matter con-tent.The plant height,plant expansion,maximum leaf length×leaf width,single plant weight and yield of cabbage in T4 treatment with new biochar based fertilizer were significantly higher than those in T1,T2 and T3 treatment(P<0.05),although there was no significant difference with CK(P>0.05),but all indicators were better than CK.[Conclusion]This study provides data support for improving soil quality in facility agriculture and making rational use of new biochar based fertilizers.
