Abstract
The effects of N,P and K fertilization on elements in fruits of Korla fragrant pear(Pyrus brestschneideri) were experimented in the pear garden on 20 years old trees.The elements in the fruits studied were Ca,Mg,Fe,Zn,Cu,Mn and Na.The experimental results showed that applying N,P and K to the pear trees could significantly increase the contents of Ca,Mg,Fe,Zn,Cu,Mn and Na in the fruits.Among which,N had significant effect on Mg,Zn,Cu and Na,P had significant effect on Ca,and the K had the significant effect on Mn.Under the proper proportion of N,P and K,the content of Fe in fruits could achieve the highest value.It was also found that in the fruits of Korla fragrant pear,the contents of Ca,Mg,Fe and Na were relatively high,whereas the contents of Zn,Cu and Mn were relatively low.
