摘要
在田间条件下,进行了给20年树龄的库尔勒香梨树施用不同配比氮、磷、钾肥,对其梨果的Ca、Mg、Fe、Zn、Cu、Mn、Na 7种重要元素含量影响的试验研究。结果表明,对其树体施用配比的氮、磷、钾肥能明显提高梨果的Ca、Mg、Fe、Zn、Cu、Mn、Na元素的含量,其中施用氮肥对梨果中的Mg、Zn、Cu、Na元素含量的提高效果显著,施用磷肥对梨果中Ca元素含量的提高效果显著,施用钾肥对梨果中Mn元素含量的提高效果显著,当施用的氮、磷、钾配比较为适当时,果实中的Fe元素含量最高。研究结果还表明,库尔勒香梨果实中,Ca、Mg、Fe、Na元素的含量相对较高,Zn、Cu、Mn元素的含量相对较低。
The effects of N, P and K fertilization on elements in fruits of Korla fragrant pear （Pyrus brestschnei- deri） 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 eould signifi- cantly 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 eould 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 con- tents of Zn, Cu and Mn were relatively low.
