摘要
在大小年明显的毛竹材用林纯林中,研究了不同施肥时间(5月份和8月份)对毛竹新竹株数、胸径和新竹高的影响。结果表明:施肥能极显著地增加毛竹新竹株数、胸径和新竹高;不同月份施肥对毛竹新竹各项指标的影响存在差异,以5月份施肥毛竹新竹株数、胸径和竹林高度表现最好。因此,在毛竹材用林经营中,要获得竹材高产、经济高效,最佳施肥时间为毛竹春笋小年的5月份。
The effects of different fertilization times（May and August） on the culm number,the DBH and the new culm height in the pure forest of Phyllostachys edulis with distinctly on-and off-year were studied. The results showed that fertilization could significantly increase the number,the DBH and the height of new culms,and the effects of the fertilization in different months on these indexes were different. The best fertilization time was in May which had the best effect on the new culm number,DBH and height. Therefore,the best time to fertilize is in May for Ph. edulis with off-year of spring shoots,which will achieve the high yields and best economic efficiency for moso timber forest management.
