- 摘要：在科学施肥的基础上，对20 a树龄的库尔勒香梨进行了生育期树体长势与产量监测，分析了香梨在年生长周期及不同时期（春季、夏季、秋季）树体基径、树高、梢条和叶片的动态变化。结果表明：4～10月为香梨生长期，夏季（5月5日至8月7日）为香梨枝干生理生长最快时期，基径、树高、梢粗和梢长的增长量最大；春季（4月1日至5月5日）为香梨叶片生理生长最快时期，叶片厚度、叶绿素含量及叶面积指数增长量也最大；香梨单果重119.24 g，产量1 745.24 kg/667m2，属中产水平。
- Abstract:
- On the basis of the scientific fertilization，the growth and yield of 20 years Korla fragrant pear in growth period in the field were monitored，and the dynamic variation of basal diameter，plant height，shoot and leaf of Pyrus brestschneideri Rehd tree in the annual growth cycle and in different periods (spring，summer，autumn) were analyzed.The results showed that the annual growth cycle of Pyrus brestschneideri Rehd tree was between April and October，the branches physiology growth of Pyrus brestschneideri Rehd tree was the fastest in summer(from May 5th to August 7th)，the growth of basal diameter，plant height，shoot diameter and shoot length were the largest.The physiological growth of leaves was the fastest in spring (from April 1st to May 5th)，the growth of leaf thickness，chlorophyll content and LAI were the largest too.The single fruit weight of Korla fragrant pear was 119.24 g，the yield was 1 745.24 kg/667m2，and it belonged to middle level.
