摘要
为了探讨单氰胺对大樱桃萌芽和成熟期的影响,萌芽前,在平度、泰安两地的“红灯”樱桃树上喷洒单氰胺1.5%和2.5%溶液。平度保护地的施药时间为2003年12月24日,泰安保护地和露地的施药时间分别为2004年1月12日和2月10日。试验结果表明,单氰胺能有效促进大樱桃萌芽和开花。平度试验点:经单氰胺处理的樱桃萌芽、开花、成熟期分别比对照提前13d、8d、7d,单果重略小于对照。泰安试验点:经单氰胺处理的萌芽期比对照提前7d,但果实成熟期与对照差异不明显。因此,单氰胺在大樱桃上的作用效果与施药时期有关。
Experiments were conducted in Pingdu and Taian of Shandong Province to determine the effects of hydrogen cyanamide （Dormex） sprays on vegetative and reproductive growth of sweet cherry（Hongdeng）. In Pingdu greenhouse, cherry plants were sprayed to drip with 1.5% and 2.5% of hydrogen cyanamide on 24 Dec. 2003. In Taian greenhouse and field, cherry plants were sprayed with the same concentration on 12 Jan. and 10 Feb. 2004 respectively. For all experiments, plants were dormant and leafless at the time of spray applications. The results showed that hydrogen cyanamide effectively induced vegetative budbreak and flowering. In Pingdu, hydrogen cyanamide sprays advanced budbreak, flowering and fruit harvast time by 13, 8 and 7 days, but decreased mean fruit fresh weight compared to untreated. In Taian, hydrogen eyanamide advanced budbreak by 7 days, but fruit ripening no marked difference with control. The effects of hydrogen cyanamide on sweet cherry had relation to the treating time.
