Abstract:: With copper base nutrition protective agent(CBN1)，iron-copper base nutrition protective agent（CBN2），boron-zinc-copper base nutrition protective agent（CBN3）as materials，the effects of CBN on apple fruit quality were investigated by field experiment on apple tree compared to conventional Bordeaux Mixture (CBM).The results showed that CBN had the same disease resisting ability with CBM，and did not make the yield and quality reduce.Copper content in leaves and fruit was significantly reduced by CBN.Moreover，copper-based nutrition protective powder with iron (CBN2)，with boron and zinc (CBN3) supplied iron and zinc during different growth stages，and the contents of iron and zinc in fruit were also increased.Overall，CBN could replace CBM effectively during all the growth stages of apple tree.
