摘要
对紫薇进行疏果试验的结果表明:采用40%乙烯利WC 100 mL/667m2进行疏果,药后30天单株落果率为67.08%、果序重355.6 g,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SP 0.5g/667m2、80%萘乙酸SP 5g/667m2疏果效果不明显。
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.
