对银杏３年生幼树采叶后，对新梢长度和粗度影响明显，平均长度减少３１．３％，新梢基部粗度减少１８．２％，且大叶发生数量减少；对成熟的雄株采叶，不利花的正常发育，会造成花粉数量和质量下降；对成熟的雌株采叶，会引起树势减弱，果型缩小，产量下降，总产约减产２９．８％。 After the 3-year-old young leaves of Ginkgo biloba were harvested, the length and thickness of the shoots were significantly affected, with the average length reduced by 31.3%, the shoot base reduced by 18.2%, and the number of large leaves decreased; Strains of leaves, unfavorable growth of flowers, will result in decreased the number and quality of pollen; mature leaves of the female plant will lead to weakened trees, fruit size reduced, the total output of about 29.8% reduction.
