摘要:以33年生米老排伐桩为研究对象,分析了不同伐桩基径(≤30cm、3050cm)及伐桩高度(≤5cm、520cm)对其萌芽植株数量、胸径及高度等生长状况的影响。结果表明,4个不同的伐桩基径级之间,30By taking the stumps of 33 a Mytilaria Zaosensis as the research objects, the effects of different stump basal diameters (≤30,30〈X≤40,40〈X≤50,〉50 cm) and heights (≤5,5〈Y≤10,10〈Y≤20, 〉20 cm) on DBH and height of stump sprouting were analyzed. Among four stump basal diameters,the number,DBH and height of stump sprouting were the biggest in the diameter range of 30〈X≤40 cm. The stump basal diameter demonstrated significant effects on the number of sprouting, while the influences of DBH and height of the stump were not significant. When the stump height was between ≤5 cm and 5〈Y≤10 cm,the number,DBH and height of stump sprouting were the biggest,and decreased with the stump height.
