摘要：

摘要：采用叶片分析并参考土壤养分分析来确定和调整果树施肥量的方法，对10个杏品种叶片中养分含量进行化验分析，并测定了不同杏园的土壤养分状况。结果表明，与其它果树相比，杏在落叶果树中是需肥较多的树种。不同的品种表现出一定的差异，除钾、钠、锰、铁个别品种差异显著外，其它元素含量不同品种间的差异不大。玉巴旦和凯特杏为喜钾性树种，叶片中铁的含量以凯特杏、串角滚子为高，优选1号需钠较多，明星杏钠含量为均值的1.63倍。杏叶片中Cu与K存在着相互协助作用，Fe与Ca存在着相互拮抗的作用。下里村杏园为砂石山区，东虎和冯家楼杏园处于青石山区，两石区的速效氮差异显著，不同土层对土壤养分含量的影响除速效氮外不大，因此施肥时应注意氮肥的量。

Abstract:

Abstract:Using the method of leaf and soil nutrient analysis to define and adjust fruit trees fertilizer amount,ten apricot varieties leaf nutrient contents and soil nutrient of different experimental sites were tested.The results showed that,compared with other fruit trees,apricot require more fertilizer in deciduous fruit tree,and N P K ratio is 1:0.07:0.44. Different varieties exhibits some differences,besidesK Na Mn Fe have significant difference in individual variety,other element content difference in different varieties is small.Leaf available N is 3.49%,P is 0.26% ,K is 1.54%, Ca is 1.41%,Mg is 0.36%, Cl is 0.36% ,Fe is 93ug/g, Zn is 17.86 ug/g ,Cu is 10.43 ug/g, Mn is 71.10 ug/g, Na is 263.07 ug/g.Yubadan and kate like K very much, Kate and chuanjiaogunzi contain the highest Fe in leaf , Optimization 1 requires much more Na,Na contant of Star apricot is 1.63 of mean.Different sites should fertilizer differently.
