对紫薇进行疏果试验的结果表明：采用40％乙烯利WC100mlM667m2进行疏果，药后30天单株落果率为67．08％、果序重355．6g，明显好于其他激素的疏果效果，且对苗木较为安全，基本上能达到疏果目的；75％赤霉酸SP0．5g／667m2、80％萘乙酸SP5g／667m2疏果效果不明显。
對紫薇進行疏果試驗的結果錶明：採用40％乙烯利WC100mlM667m2進行疏果，藥後30天單株落果率為67．08％、果序重355．6g，明顯好于其他激素的疏果效果，且對苗木較為安全，基本上能達到疏果目的；75％赤黴痠SP0．5g／667m2、80％萘乙痠SP5g／667m2疏果效果不明顯。

With 40% ethephon WC, 75% gibberellic acid SP, 80% naphthylaeetic acid sp for fruit thinning of Lagerstroemia indica tests. The results showed that 40% ethephon WC for fruit thinning, the rate of fruit drop after the 30d strain was 67. 8%, the weight of fruiting - cymes was 355. 6 g, significantly better than the other of weeds effects, and more security, can basically achieve the purpose of fruit thinning. The thinning effect of 75% gibberellic acid SP and 80% naphthylacetic acid sp was not obvious.
