| 摘 要： | 该文对杨树生物能源林参试品种不同密度的生长节律进行观测研究,得出杨树各品种树高和地径生长速峰期均处于6~8月份,与华北地区水、热同期,有利于生物量的积累;且地径生长高峰期比树高生长高峰期滞后或基本同步。对各品种不同密度的生长节律进行比较得出：不同密度对各杨树品种树高和地径的生长量有明显的影响,而对整个生长期内的生长节律无太大影响。

| Abstract: | The growth rhythm of different poplar species was tested in poplar energy forest with different afforestation density.The result showed that peak period of tree height and diameter at butt end growth were same with precipitation and caloric in North China in June,July and August.It was in favor of accumulation of biomass.The peak period of thickness growth was happen after or same with high growth.The effect of afforestation density on tree height and diameter at butt end growth was marked,but the growth rh... |
