摘　　要：[目的]研究混合药剂对番荔枝采后脱叶率的影响。[方法]以"非洲骄傲"番荔枝为材料,采用4因素3水平的正交试验设计,研究采后喷施脱叶剂(三氯乙酸+碘化钾+乙烯利+噻苯隆)对番荔枝脱叶率的影响。[结果]在采后修剪前7 d喷施混合药剂(1.0 g/L三氯乙酸+3 g/L碘化钾+12%乙烯利+5 g/L噻苯隆),可以基本去除番荔枝叶片,脱叶率达92.04%,不仅有利于采后修剪工作的开展,而且能促进枝芽的萌发。[结论]此次试验脱叶效果最好的药剂组合是1.0 g/L三氯乙酸+3 g/L碘化钾+12%乙烯利+5 g/L噻苯隆。[Objective] The aim was to study effects of mixed chemicals on defoliation rate of Annona squamosa after harvesting.[Method] Defo-liant trichloroacetic acid （TCA）＋kalium jodatum（KI） ＋ethephon （ETH） thidiazuron （TDZ） was designed by using an orthogonal experimen-tal with four factors and three levels for spraying after harvest and the effect of the defoliant on defoliation rate of Annona squamos cv.African pride were studied.[Result] The result showed that spraying with the defoliant （1.0 g/L TCA＋3 g/L KI＋12% ETH＋5 g/L TDZ） in the first 7d after harvest pruning can basically remove the leaf of Annona squamosa with defoliation rate as 92.04%,which is conducive to the development of post harvest pruning work and promoting the germination of branches.[Conclusion] The medicament combination of 1.0 g/L TCA＋3 g/L LKI＋12%ETH＋5 g/L TDZ has the best defoliation effect.
