Abstract:
Taking 1-year-old ‘Gala’ apple as material,the effect of controlled release fertilizer on young orchard soil were investigated，including soil organic matter，pH value and the content of mineral elements such as N，P，K，Ca，Mg，Cu，Fe，Zn，Mn.The results showed that pH value and the content of organic matter reduced，and the pH value of the orchard applying controlled-release fertilizer was higher than that applying common compound fertilizer.The soil nitrogen content increased，otherwise available phosphorus contents reduced followed with application of controlled release fertilizer，but the content of potassium didn’t change significantly.Meanwhile，the content of Fe，Cu and Zn increased followed with the application.
