Abstract
【Objective】 The research is to study the effect of balance fertilization on apple fruit yield and quality in order to apply the theoretical foundation for the high quality of apple production in Weibei plateau.【Meyhod】 Totally 64 soil samples were taken in grid from apple achard in Xiuli villagge of Shaanxi Weibei dry-land and effects of different fertilizer treatments on apple fruit yield and apple quality were studied.【Result】 The results by ASI method indicated that 36.1%,41.7%,80.6% and 77.8% of soil samples for the content of available N,available K,available Zn and available Mn went under the critical value.13.9%,11.1% and 16.7% of the soil samples for the content of available P,available S and available Fe were under the critical value.It shows that the soil was poor in available N,K,Zn and available Mn and abundent in available P,S and Fe in the area respectively.The 3-year experiment showed that fertilizer supply could increase apple yield in the range from 12.6% to 36.4%.The order of increase rate among N,P and K was NKP.【Conclusion】 Only the balanced application of N,P and K can have the best of the apple yield,quality and benefit.The reasonable quantity of fertilization should be N 0.3 kg/tree,P2O5 0.1 kg/tree,K2O 0.25 kg/tree,and it's necessary to apply some of Zn and Mn fertilizer.
