| 摘 要： | 为了有效防治果树缺铁黄叶病，本研究对山东肥城市肥桃主栽区的25个桃园130棵桃树和泰安、德州、烟台3地区的18个苹果园263株苹果树进行了分析测定。结果表明，桃和苹果盛花期花全铁含量和变幅显著高于5－6月、7－8月、10月叶片。桃树花全铁含量与5月、10月桃树叶片全铁和叶绿素之间密切相关，但与7月叶片全铁和叶绿素含量之间相关性不高。同时，桃花活性铁与5月10月桃叶片活性铁含量相关性较高，但与7月叶片相关性不高。苹果花全铁含量与5－6月，7－8月和10月叶片全铁和叶绿素含量之间均密切相关。初步表明用苹果和桃花全铁含量更容易区分正常果树和缺铁果树，能更好地预测果树生长早期铁营养状况和及早采取相应的防治措施，可以作为果要对缺铁诊断指标。 |

| Abstract: | Investigations was conducted with 130 peach trees in 25 orchards at Feicheng County, 263 apple trees in 18 orchards at Taian, Dezhou, Yantai area in Shandong Province, and iron concentration in flowers and leaves were analyzed. The results showed that the iron concentrations and the range in peach and apple trees flowers were much higher than it in leaves sampled in May to June, July to August and October. The iron concentrations in peach flowers were correlated well with the iron concentration and chlorophyll content in leaves sampled in May and October, but not with July. Furthermore, active iron in peach flowers were also correlated well with active iron in peach leaves sampled in May and October, but not with that in July. There were good correlations between iron concentration in apple flowers and the iron concentrations and chlorophyll contents in leaves sampled at each time. It suggested that it was easily to distinguish iron deficient fruit trees from ironadequate ones with iron concentration in both flowers, and could be an good iron deficient diagnosing index for predicting iron supply in fruit trees. |
| Keywords: | peach apple flower leaf iron deficient chlorosis diagnosing |
