以‘东湖早’和‘早钟6号’枇杷为材料,分析比较其叶片营养状况,探讨枇杷养分吸收特性。结果表明,‘东湖早’枇杷春梢叶片氮含量、可溶性蛋白、叶绿素和类胡萝卜素含量均显著高于‘早钟6号’,而2个品种的夏梢、秋梢、冬梢均无显著性差异;2个品种的春梢、夏梢、秋梢和冬梢叶片全磷含量均无显著性差异;2个品种的春梢叶片全钾含量无显著性差异,‘东湖早’枇杷夏梢叶片全钾含量显著低于‘早钟6号’,秋梢和冬梢叶片均显著高于‘早钟6号’。2个品种氮的吸收高峰均在冬梢,磷和钾的吸收高峰均在春梢。
以‘東湖早’和‘早鐘6號’枇杷為材料,分析比較其葉片營養狀況,探討枇杷養分吸收特性。結果錶明,‘東湖早’枇杷春梢葉片氮含量、可溶性蛋白、葉綠素和類鬍蘿蔔素含量均顯著高于‘早鐘6號’,而2箇品種的夏梢、鞦梢、鼕梢均無顯著性差異;2箇品種的春梢、夏梢、鞦梢和鼕梢葉片全燐含量均無顯著性差異;2箇品種的春梢葉片全鉀含量無顯著性差異,‘東湖早’枇杷夏梢葉片全鉀含量顯著低于‘早鐘6號’,鞦梢和鼕梢葉片均顯著高于‘早鐘6號’。2箇品種氮的吸收高峰均在鼕梢,燐和鉀的吸收高峰均在春梢。

The nutritional status on leaves of loquat (Eriobotrya japonica 'Zaozhong 6' and 'Donghuzao') was compared, and their characteristics of nutrient absorption were probed. The results showed that the contents of the nitrogen, soluble protein, chlorophyll and carotenoids of loquat leaves on spring shoots in variety 'Donghuzao' were all significantly higher than in variety 'Zaozhong 6'. However, there were no significant difference of leaves on summer, autumn and winter shoots between two loquat varieties. There was no significant difference of the contents of phosphorus of leaves on spring, summer, autumn and winter shoots between two loquat varieties. The contents of potassium of leaves on spring shoots of two loquat varieties had no significant difference. While, the contents of potassium of leaves on autumn and winter shoots in variety 'Donghuzao' were all significantly higher than in variety 'Zaozhong 6', summer shoots significantly lower. The absorption peak of nitrogen of two loquat varieties were both in winter shoots, and that of phosphorus and potassium were both in spring shoots.
