摘要
对孔林暖温带落叶阔叶林和针叶林中312种种子植物的开花、结果的物候情况进行了研究,每半月调查1次,持续观察13个月.生活型包括乔木、灌木、草本3种类型.结果表明:孔林植物群落中植物的开花物候和结果物候都相对集中,花期主要集中于4-9月,其中以6、7两月最多;果期主要集中于6-10月,其中以8、9、10 3个月最高.不同生活型植物在一年中具有不同的开花、结果高峰期.开花高峰期依次出现在乔木层—灌木丛—草本层,木本植物先于草本植物;结果高峰期依次出现在草本层—灌木层—乔木层,木本植物与草本植物的结果高峰期是基本重叠的.
The phenology of 312 seed plants of the warm temperate deciduous broad -leaved forest and conifer forest in Confucius Cemetery, Qufu have been observed half-monthly for 13 months. The life forms monitored were trees, shrubs and herbs. The results show that the flowering and fruiting phenologies both aggregate in a few months. These plants flower mainly from April to September, of which June and July occupy the highest percentage, and fruit mainly from June to October, of which August, September and October occupy the highest percentage. Life forms have flowering and fruiting peaks at different times of the year. The flowering peak appears in trees, shrubs and herbs in turn and woody plants are earlier than herbs. The fruiting peak appears in herbs, shrubs and trees in turn ,woody plants and herbs are nearly at the same time.
