| 中文摘要: |
| 以6 年生砂糖橘（Citrus reticulata Blanco）结果树为对象，研究了幼果期“以梢控梢”保果对
其坐果、果实品质等的影响及其综合效益分析。结果表明，与传统的人工抹梢保果方式（CK）相比，在树
冠顶部保留适量夏梢生长，可显著抑制树体中下部夏梢的抽生，从而达到高效、节本保果目的。从3 个“以
梢控梢”保果处理的综合表现可知，按每1 m2 树冠投影面积保留10 条夏梢的保果方法，夏季树体夏梢抽
生数量比对照下降93.6%，座果率、平均单株产量分别提高6.95% 和10.3%，保果成本下降66.1%，且果实
品质优良，是砂糖橘高效节本保果的最佳方案。 |
| 英文摘要: |
| Six-year-old mature trees of‘ Shatangju’ mandarin（Citrus reticulata Blanco） were used to
investigate the fruit retention influence of summer shoots control with other shoot growth in summer，and the
comprehensive benefit was also analyzed. Compared with traditional manually removing shoot to control fruitlet
abscission（ CK），the reservation of suitable summer shoot on the top canopy，can significantly inhibit the emergence
of other summer shoots in the middle-lower part of trees，and the purpose of high efficient and cost-cutting can also
be realized. Among these three summer shoots control with other shoot growth treatments，the preservation of ten
summer shoots per square metre of crow projected area was the optimum scheme for fruit setting of citrus‘ Shatangju’
with high efficiency and low cost. Compared with the control，the amount of summer shoots reduced by 93.6%，the
rate of fruit setting and the average yield of single plant increased respectively by 6.95% and 10.3%，and the cost of
fruit setting reduced by 66.1%. |
