Abstract:
To assess the formulated fertilization based on leaf elements on yield and soluble solids content (SSC) of strawberry fruit.Strawberry cultivar ‘Ssanta’ was used as test material，three kinds of fertilization formulas (FF 1，2，3) were obtained from leaf element analysis which was used to test the content of mineral elements of strawberry leaves.Combine with proportional injection pump system in water and fertilizer integration，‘Ssanta’ was cultured and managed in greenhouse.The effects of the formulas were evaluated by regular testing for fruit SSC，yield and yield components.The results showed that under the fertilization management of FF 1，2，3，total yield，average yield per plant，fruit number per plant and single fruit weight of strawberry were significantly higher than the conventional way (P＜0.05).The total yield，average yield per plant and single fruit weight were higher when used FF 3 than used FF 1 and FF 2.The SSC under FF 2 was the highest while there was no significant difference with FF 1 and FF 3.The results indicated that strawberry planting fertilization was more suitable to meet their own needs nutrients supply.The formulas of fertilization based on strawberry leaf mineral element analysis was significantly increased the fruit yield and SSC.Multiple sets of proportional injection pump in parallel ensured the balance of the fertilizer proportion and dosing accuracy which had the application prospect of promotion.The method was more scientific and reasonable.
