| 摘要: |
| 简括综述了果树叶片是果树 N 素库之一、叶片 N 素回撒的时间和形态、叶片回撤 N 素的贮藏部位和形态、早春果树生长发育对叶片回撒 N 素的再利用及其生物学效应;讨论了增加叶片回撤 N 素的措施。在果树局部叶片施用(15)~N-尿素的示踪研究中,阐明了局部贮藏占优势及其次年再利用的特点;讨论了应用植物生长调节剂如 NAA 和乙烯利(CEPA)对促进叶内氮素回撤、节约氮素的实用意义。 |

| Abstract: |
| The major part of this minireview is author' s research work in recent years,addition to some others'.It briefly reviewed some research acqui- sitions as follows:the role of storage nitrogen in fruit trees;the role of lea- ves as a nitrogen pool in fruit trees; the time and form of nitrogen transported out of leaves;the site and form of storage nitrogen come from leaves; in the spring the reutilization and biological effects of nitrogen come from leaves last year;and the way which cou|d promote nitrogen tra... |
