The results showed that the rhizosphere medicine could increase survival rate, height, DBH, relative turgidity of bark and tree capacitance and decrease morbidity and contagious index dramatically. Two kinds of application methods were adopted: one was called the soil-mixed method and another called the root-dipping method.
