Abstract: The objective is to solve the problems of unreasonable fertilizer input, fruit yield decrease and poor fruit quality under substrate cultivation of strawberry. Taking Fragaria × ananassa‘Benihoppe’as the experimental material, and farmer''s practice (FP) as the control, we studied the effects of the rate of recovering, plant height, stem diameter, leaf area, flowering budding rate, yield, quality and economic benefits of strawberry under substrate cultivation. Compared with the farmer''s practice (FP), the optimized fertilization (OPT) reduced the seedling time by 5-8 days, increased the seedling rate by 43.3%, the stem diameter by 20.4%, and the leaf area significantly by 77.1%. Compared with the FP, the OPT could significantly increase the fruit weight and fruit number of strawberry, and the yield of strawberry was increased by 40.9% , the average enhancement of strawberry acidity was 15.8%, and economic benefits of strawberry was improved by 53.2 yuan/m2.
