Abstract: In order to improve the fertilizer utilization efficiency in greenhouse strawberry,the water-soluble fertilizer containing amino acid（including PASP）was used as the experimental fertilizer,and the commercially available water-soluble fertilizer was used as the control fertilizer.After the strawberry seedlings were transplanted and planted,the corresponding fertilizer was applied through the drip irrigation system to observe and analyze the whole growth process,yield,quality and economic benefits of greenhouse strawberry.The resultsshowed that the application of amino acid water-soluble fertilizer 75L·ha^-1（treatment 2）every 15days from the budding stage promoted the entire growth process of greenhouse strawberries,significantly reducing the dead seedling rate of the tested greenhouse strawberries to 5.16%（CK was 11.43%）;At the same time,it can promoted its nutritional growth,increase the fruit setting rate to 73.38%（CK was 56.70%）,promoted early ripening of strawberries（which can be listed 6days earlier than CK）,and thereby improve the appearance quality of the fruit（single fruit weight increased by 23.94%compared to CK,abnormal fruit rate decreased from 11.28%to5.60%）and internal quality（solid content increased by 44.83%,titratable acid decreased by 29.49%,VC increased by 31.99%,and fruit hardness increased by 31.67%）,significantly improved greenhouse strawberry yield and economic benefits.
