摘要
对种植于贵州安顺市的白玉枇杷的枝梢生长特性进行了观察,结果表明:白玉枇杷枝梢一年四季没有明显的休眠季节.1月底开始抽生新梢,一年有3次生长高峰:2月上旬至4月下旬抽生春梢,是第一次生长高峰,生长时间最长,枝梢抽生整齐、数量较多,数量仅次于夏梢,生长量不大;6月上旬至7月下旬抽生夏梢,是第二次生长高峰,枝梢抽生整齐、数量多,生长量为一年之最;8月中下旬至9月上旬抽生秋梢,生长总量仅次于夏梢,是第三次生长高峰.在一定范围内,枝梢的生长量与气温呈正相关.
The shoot growth characteristics of baiyu loquat in Anshun,Guizhou Province,has been investigated in the current work.The results show that baiyu loquat shoots grow without stop in a year.The end of January,baiyu loquats sprout new shoots,and there are three growth peaks with a year.The first peak takes place from early February to late April,and shoots sprout almost in the same time,whose number is less than the summer shoots.The second growth peak emerges from early June to late July,and the number of summer shoots is the largest in a year.From late August to early September,autumn shoots occur.Furthermore,the close correlations between the temperature and shoot growth have been investigated herein.
