Abstract:
The 7-year-old Dongzao was used as the test material,and different concentrations of T1 (2.5 mL·L-1),T2 (5.0 mL·L-1),T3 (10.0 mL·L-1) and T4 (15.0 mL·L-1) of nano-iron and nano-zinc mixture were sprayed on the leaf surface during fruit development.The effect of nano-iron and nano-zinc mixture on the quality of Dongzao leaves and fruits was studied with spraying water as a control,in order to screen out the suitable concentration of nano-iron and nano-zinc mixture to promote the quality of Dongzao.The results showed that foliar application of 10.0 mL·L-1nano-iron-zinc foliar fertilizer significantly improved the fruit quality of Dongzao,increased the single fruit weight,fruit hardness,soluble solids content,vitamin C content and solid-acid ratio,and reduced the titratable acid content,improved the photosynthetic pigment content and photosynthesis of Dongzao leaves；spraying concentration of 15.0 mL·L-1 nano-iron-zinc foliar fertilizer had the best effect on the content of iron and zinc in Dongzao leaves and fruits.Therefore,foliar application of nano-iron and zinc foliar fertilizer could promote the accumulation of iron and zinc in Dongzao leaves,increase photosynthetic pigments content,promote photosynthesis,and improve fruit quality.
