摘　　要：为研究椰子抽花和座果规律,以‘文椰2号’、‘文椰3号’和‘文椰4号’为研究对象,对其不同月份花序数量、雌花数量及坐果率进行统计。试验表明,在无水肥管理的条件下,‘文椰2号’全年抽生花序12.85个,雌花数量234.93个,8月龄果坐果率19.67%;‘文椰3号’全年抽生花序12.36个,雌花数量193.64个,8月龄果坐果率18.83%;‘文椰4号’全年抽生花序16.05个,雌花数量415.10个,8月龄果坐果率9.52%。实际生产中,3个品种在水肥供应充足的情况下,平均每年可产果100个以上,水肥管理对于椰子的增产效果十分明显。The paper aims to study the law of coconut flower blooming and fruit setting.Taking‘Wenye No.2’,‘Wenye No.3’and‘Wenye No.4’as materials,and the number of inflorescences and female flowers,and the fruit-setting rate in different months were counted.The results showed that:under the condition of no water and fertilizer management,for‘Wenye No.2’,there were 12.85 inflorescences and 234.93 female flowers per year,and the fruit-setting rate of 8-month-old fruit was 19.67%.For‘Wenye No.3’,there were 12.36 inflorescences and 193.64 female flowers per year,and the fruit-setting rate of 8-month-old fruit was 18.83%.For‘Wenye No.4’,there were 16.05 inflorescences and 415.10 female flowers per year,and the fruit-setting rate of 8-month-old fruit was 9.52%.In the actual production,under the condition of sufficient supply of water and fertilizer,all the 3 varieties could produce more than 100 fruits per year on average,which shows that the water and fertilizer management has a very obvious effect on the yield of coconut.
