蜜蜂授粉与喷施赤霉素对枣树坐果及品质的影响

摘要

采用田间试验与实验室测定相结合的方法,研究了蜜蜂授粉与喷施赤霉素对枣果坐果、生长、产量、品质与有仁百分比的影响.结果表明,蜜蜂授粉比喷施赤霉素后枣树的的坐果率可提高0.07百分点,株产量增加34％,单果质量提高16.75％,总糖提高4.4百分点.可见,枣树可以采用蜜蜂代替喷施赤霉素进行授粉,以达到增产的效果,实现绿色果品生产.%Using field experiment and laboratory determination method, effects of bee pollination and gibberellin on jujube fruit setting, growth, yield, quality and percentage of pit were studied. The results showed that bee pollination was better than gibberellin, fruit setting rate increased 0.07 percentage point, per plant yield increased 34%, single fruit weight increased 16.75%, total sugar increased 4.4 percentage point. These data indicated that the Jujube pollination could use the bees pollinated instead of spraying gibberellic acid pollination to increase yield and achieve the green fruit production.
