在河北省灵寿县进行了采伐季节、伐桩直径、桩高及树龄对刺槐当年萌芽更新效果影响的初步研究。结果表明:①非生长季采伐的萌芽更新效果明显优于生长季节内采伐,即前者的萌条数量、萌条径高生长及生物量显著高于后者;②伐桩直径对萌条数及伐桩萌条总生物量有显著影响,而各径级伐桩萌条的径高生长差异不显著;③在6～15a生的年龄范围内或伐桩高度低于30cm时,伐桩萌芽力是均等的,即树龄和桩高对伐桩的萌芽更新没有显著影响。
In Lingshou County, Hebei Province, a preliminary study was conducted on the effects of cutting season, pile diameter, pile height and age on the germination and regeneration of Robinia pseudoacacia. The results showed that: (1) The regeneration effect of harvesting in non-growing season was significantly better than that in the growing season, that is, the former number of sprouting, growth of sprouting height and biomass were significantly higher than the latter; (2) There was significant difference in the total biomass of sprouted stumps but no significant difference in the height growth of stumps of various diameters of stumps. (3) In the age range of 6 ~ 15 years old or when the height of stumps was less than 30 cm, Is equal, that is, tree age and pile height have no significant effect on the sprout regeneration of stumps.
