Abstract

Abstract:

To explore the effect of silicon fertilizer on root-restricted cultivation of sweet cherry, this experiment explored the effects of three different application methods of silicon fertilizer on leaf structure, photosynthetic characteristics, fruit quality and yield of Hongmi and Brooks sweet cherry in root-restricted containers. Various indicators under three different application methods of silicon fertilizer were comprehensively evaluated to select the optimal silicon fertilizer application scheme. The results showed that silicon fertilizer could effectively improve the leaf structure of sweet cherry, enhance photosynthetic effect, and improve the fruit quality and yield of sweet cherry. Among them, the spraying treatment could more effectively increase the chlorophyll content, nitrogen content, net photosynthetic rate and transpiration rate of leaves. Irrigation treatment was superior to spraying treatment in improving yield per plant of sweet cherry. While the combination of spraying and irrigation treatment had the best comprehensive performance, significantly (p<0.05) improved the single fruit weight, soluble solids content, and yield per plant of sweet cherries. Compared with the control treatment, the single fruit weight increased by more than 16.45%, the soluble solids content increased by more than 1.36 percentage points, and the yield per plant increased by more than 23.80%.

Key words: silicon fertilizer, sweet cherry, root-restricted cultivation
