Effects of Three Foliar Fertilizers on Quality and Photosynthetic Characteristics of Hawthorn
This study aimed to investigate the effects of three foliar fertilizers on the photosynthetic characteristics,single fruit quality and yield of hawthorn,and provided references for foliar fertilization of hawthorn.The photosynthetic rate,transpiration rate,intercellular CO2 concentration,stomatal conductance and single fruit weight of hawthorn treated with different concentrations of foliar fertilizer were measured.The results showed that,under appropriate concentration fertilization treatment,the photosynthetic rate,transpiration rate and stomatal conductance of hawthorn leaves increased significantly,while the intercellular CO2 concentration decreased.Specifically,fish protein peptide foliar fertilizer showed the best performance,with a 57.22%and 57.51%increase in net photosynthetic rate and transpiration rate,respectively.The intercellular CO2 concentration was significantly reduced by the three foliar fertilizers.In addition,the single fruit weight of hawthorn increased significantly under fertilization treatments,and the effect of fermented fulvic acid foliar fertilizer was the most significant,with the highest increase rate of 68.49%.Foliar application of fertilizers increased significantly the content of Vc,titratable acid,anthocyanins,and soluble solids in hawthorn fruits,and the effect of fermented fulvic acid foliar fertilizer showing the best promoting effect.
