A Summary of the Effects of the Steiner Products on Apple

[Objective]In order to verify the application effect of Steiner series products,the experiment was carried out on apple.[Methods]Different combinations of apple fertilization were used in the field plot experiment.[Results]The results showed that the sugar content,soluble solid content and vitamin C content of apple were increased by 2.1%,0.9% and 5.18 mg/kg by steiner compared with conventional fertilization.Soil PH increased by 0.3 unit and soil bulk density decreased by 0.03 g/cm³.[Conclusion]The comprehensive test results showed that the application of Steiner products could significantly improve the main quality indexes of apple,and thus improve the quality of apple.At the same time,it has a good effect on inhibiting and improving soil acidification,preventing soil compaction and improving soil physical properties.
