管道输液滴干对苹果缺铁失绿症的影响

为探索防止果树缺铁失绿症方案,该研究以Fe-N为铁肥品种,以管道输液滴干的方式对中秋王苹果树输入不同浓度的溶液,测定叶片的叶绿素相对含量（SPAD值）、百叶重、百叶厚、全铁和活性铁含量及荧光参数等指标。结果表明：Fe-N管道输液滴干处理显著提高了苹果叶片的SPAD值、百叶重、百叶厚、全铁以及活性铁的含量,发现叶片SPAD值与活性铁含量之间呈现良好的线性关系（相关系数为0.899）,表明叶片SPAD值可以作为苹果缺铁诊断指标,同时也说明了苹果树体叶片黄化主要是由于活性铁含量低所致。16.4×10-（-3）mol·L-（-1）Fe-N溶液处理的叶片SPAD值、百叶重、百叶厚、全铁及活性铁含量显著高...

Summary:为探索防止果树缺铁失绿症方案,该研究以Fe-N为铁肥品种,以管道输液滴干的方式对中秋王苹果树输入不同浓度的溶液,测定叶片的叶绿素相对含量（SPAD值）、百叶重、百叶厚、全铁和活性铁含量及荧光参数等指标。结果表明：Fe-N管道输液滴干处理显著提高了苹果叶片的SPAD值、百叶重、百叶厚、全铁以及活性铁的含量,发现叶片SPAD值与活性铁含量之间呈现良好的线性关系（相关系数为0.899）,表明叶片SPAD值可以作为苹果缺铁诊断指标,同时也说明了苹果树体叶片黄化主要是由于活性铁含量低所致。16.4×10-（-3）mol·L-（-1）Fe-N溶液处理的叶片SPAD值、百叶重、百叶厚、全铁及活性铁含量显著高于其它处理,分别比对照提高了89.66%、20.42%、9.26%、158.0%、277.4%,该处理荧光参数也达到了较优水平。该研究结果为管道输液滴干防止苹果缺铁失绿症的应用奠定了基础。

In order to explore the simple and labor-saving program of preventing iron deficiency chlorosis in fruit trees,we studied the effects of Fe-N solutions of different concentrations by pipeline transfusion and drip,contrasted by conventional management by determining the leaf SPAD value,hecto-leaf weight,hecto-leaf thickness,the content of total iron and active iron and so on. The results showed that the treatment of iron fertilizer pipeline transfusion significantly increased leaf SPAD value,hecto-leaf weight and hecto-leaf thickness,the content of total iron and active iron in leaves,while the chlorophyll fluorescence parameters also had a major impact. In addition,SPAD value and
