果树高产素的研制及其增产效应的研究

Introduction of asynthetic Growth Substance for Fruit Trees with Reference toIts Production Promoting Effects

果树高产素是根据果树生长发育规律和合成代谢规律进行研制的。１９８９～１９９２年连续４年对其进行大面积、多品种、多点测试，结果证明，果树高产素不仅能有效防治苹果早期落叶病和果锈病，提高叶片光合效率，延缓器官衰老与果树落叶，而且具有提高苹果树花序座果率和花朵座果率、克服大小年结果、促进膨果、增加果实着色度和糖含量、提高苹果产量的功能。

ABSTRACT This synthetic growth substance for fruit trees. or fruit yield promoter. wasdeveloped in accordance with the metabolic law of fruit trees. The extensive performance testof it with the apple tree from 1989 through 1992 indicated that it could not only prevent thepremature shedding of leaves and control fruit rust. but it could also raise the fruit- set per-centage. avoid the alternate bearing problem.speed expansion of the fruitlet. promote fruitcoloration. and increase the sugar content of the fruit.
