摘要
根据文献报道对苹果的化学疏花疏果研究及其应用情况进行了综述和分析。苹果化学疏花疏果从1930年开始研究以来,发现20余种化学药剂有疏花疏果作用,其中实际应用最广泛的有西维因、NAA、石硫合剂,西维因和NAA用于疏果,石硫合剂用于疏花。但由于这些疏花疏果剂及其应用效果都存在一定缺点,近年来各国研究工作者致力于研究和寻找无公害的疏花疏果剂。影响化学疏花疏果的因子基本明确,有关研究报道比较一致。对化学疏花疏果剂的作用机理研究结果不一,尚存在分歧。
Study on chemical thinning for apple trees and its application are summarized. It has been proved that more than 20 kinds of chemical agents axe valuable and useful for chemical thinning of apple trees since the research was started in 1930. Among those chemical agents the most widely used agent is Sevin. NAA is used as fruit thinner and lime sulfur used as flower thinner. Since each of these agents has showed some limitations as being applied on trees, scientists in different countries have begun to focus their study on finding some chemical friendly nonsense-free thinner. It has been definitely known that what factors influencing the effect of chemical thinning of trees, and different reporters share similar views on this, but they get different results when studying on the mechanism of thinners.
