摘要
对1 a生蓝莓"斯巴坦"和"北陆"施入不同氮素形态的营养液,分析叶片矿质元素含量。结果表明:不同氮素形态处理对2种蓝莓叶片中N含量影响明显且结果基本一致,其中铵态氮处理的叶片N含量最高。不同氮素形态处理对2种蓝莓叶片中其他矿质元素含量影响不明显且2品种之间有所差别,铵态氮处理的"斯巴坦"叶片中P、K、Ca、Mg、Mn含量最高,铵态氮∶硝态氮=1∶1处理的"北陆"叶片中P、K、Ca、Fe、Mn、B含量最高。
One-year-old "Spartan" and "North" blueberry was selected and different nitrogen form of fertilizer were applied in soil.Leaf mineral element content was analysed.The result indicated that the effect of nitrogen form treatments on nitrogen constituents of two varieties of blueberry leaves was significant and basically consistent,leaf N content of NH+4-N treatment reached hightest.The effect of nitrogen form treatments of other nutritive constituents of two varieties of blueberry leaves was insignificant and different.leaf P,K,Ca,Mg,Mn content of NH+4-N of "Spartan" reached hightest,leaf P,K,Ca,Fe,Mn,B content of NH+4-N∶NO-3-N=1∶1 of"Northland" reached hightest.
