摘要
秋茄种子雨的质量和数量与时间分布影响着秋茄群落的更新演替。采用野外固定样方凋落物收集法,研究了雷州半岛太平镇麒麟村秋茄的凋落物数量质量特征,包括秋茄种子雨密度、种子雨强度、以及种子雨的时序特征等。结果表明:秋茄种子雨从当年12月初开始持续到次年5月下旬结束,种子雨有3个降落高峰,但以4月中旬降落的种子数量最多。
The quantity and quality distribution of seed rain of K. candel community affect the communityg succession. In this paper, The field station sampling method was used to investigate the characteristics of K. candel seed rain in Qiling Village, Taiping, Leizhou Peninsula. The investigation recorded the number, length and quality characteristics of K. candelg seed rain during fruiting phase and its seed rain distribution pattern, which indicated the natural seed rain peaked from March to April, when its seed rain season happened during the fruiting period from the early December, 2010 to the end of May, 2011 and the seed rain showed 3 raining peaks with the most heaviest rain peak happened in April.
