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。

Abstract:

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.

Key words: coconut, flower blooming law, female flowers, fruit-setting rate, yield
