| 摘 要： | 为验证40%福星EC对酥梨果实脱萼的影响,并探讨酥梨花序分离期的最佳施用时间和施用浓度,2008-2009年连续2a进行了田间试验.结果表明,不同时期施用40%福星EC,酥梨脱萼率增加8.7%～20.5%,形成更多的母梨,且距酥梨初花期越近,使用浓度越大,脱萼效果越好.同时,施用40%福星EC能减小果柄长度和果形指数.... |

| Abstract: | In order to study the effect of Nustar(40% Flusilazole EC) on calyx removing of crisp pear and research its optimum treatment time and concentration in calyx removing stage,the field tests were conducted in 2 years(2008-2009) continuously.The results indicated that the Nustar treatment at different time could improve fruit quality of crisp pear due to increasing the calyx removing percent by 8.7%-20.5%.The closer to the beginning of flowering treatment time was,the higher treatment concentration was,the better the calyx removing effect was.Meanwhile,the application of Nustar could reduce the length of carpophore and fruit shape index.Compared with other products,Nustar coule improve calyx removing rate 13%-25%.So,8 000X Nustar dilution solution spraying treatment was recommended to improve calyx removing percentage when it was 2-5 days before flowering. |
