Abstract:: ‘Longyin 1’ strawberry was used as test material,six kinds of materials were selected and five kinds of matrix formulations were designed: T1 grass charcoal 50%+vermiculite 50%,T2 grass charcoal 50%+slag 50%,T3 slag 43%+mushroom slag 57%,T4 grass charcoal 75%+perlite 25%,T5 grass charcoal 60%+pine needle 40%,with strawberry special matrix as control(CK),the effects of the dynamic matrix physicochemical properties on strawberry yield and the main factors affecting the physicochemical properties of the matrix were studied.The results showed that the main affecting factors of the matrix physicochemical properties were the porosity,effective potassium,alkalinity nitrogen,and weight.The physicochemical properties of T1 and CK matrix were similar,and T1 yield was significantly higher than CK,the yield increased by 19.69%.
