摘要
以广泛分布于浙江天童国家森林公园内37种主要木本植物为研究对象,采用爆芽的起始时间、高峰时间、持续时间、结束时间等爆芽物候参数研究常绿阔叶林中主要木本植物的爆芽物候同步性的特征.结果表明:(1)大部分植物爆芽起始时间集中在3月下旬,高峰时间集中在3月底4月初,结束时间集中在4月上旬;(2)不同植物爆芽同步性不一,马银花Rhododendron ovatum在所有植物中爆芽同步性最高(CV值为1.23),橄榄槭Acer olivaceum爆芽同步性最低(CV值为0.32),其余植物爆芽同步性介于两者之间;(3)37种主要本木植物爆芽的起始时间、高峰时间、结束时间同步性较高,爆芽开始早的植物,结束时间较早,且持续时间越长,结束时间越晚;(4)根据不同植物种类爆芽动态的特点,爆芽物候的格局分为3类:单峰格局、双峰格局、多峰格局.
To research synchronous characteristic of budburst phenology in evergreen broad-leaves forest, they chose 37 kinds of woody species to do experiments, and observed the budburst course of each individual, then calculated the beginning time, peaking time, ending time, duration of budburst and Cv value. The results show that： （1） Most of species begin to budburst at the last ten- day in of March, the peaking time of budburst concentrate in the end of March and the begin of April, and the end time of budburst is during the middle ten-days of April. （2） It is different of budburst synehrony among all species. Rhododendron ovatum in budburst is the most synchronous of all species, which Cv value is 1.23, while Acer olivaceum is the most asynchronous, which Cvvalue is 0. 32. The others are between the two species above. （3） It is synchronous in the beginning time, peaking time, ending time of all species. The earlier the species budburst, the earlier the species encled the process of budburst, and the longer the species last, the later the species ended budburst. （4） Based on the different budburst characteristic, the pattern of budburst can be divided into 3 types： unimodal pattern pattern, bimodality pattern, multi-peaks pattern.
