摘　　要：研究了不同修枝处理对木麻黄无性系人工林的树高、胸径、单株材积、抗风性和抗青枯病的影响。结果表明:修枝1m和修枝2m处理均能显著提高木麻黄的树高、胸径和单株材积的生长,其树高分别比不修枝的对照增加15.2%和22.7%,胸径比对照增加16.1%和14.3%,单株材积比对照增加54.5%和31.8%;2种修枝处理均能降低木麻黄人工林经台风袭击后的风倒率,但只有修枝2m处理的风倒率(6.5%)显著低于不修枝对照(33.3%)的风倒率;修枝处理也能降低台风袭击后木麻黄人工林的青枯病发病率,但3个处理间差异未达到显著程度。Effects of different pruning treatments on growth of height(H),DBH,individual volume(IV),wind-resistance(WR)and disease-resistance(DR)in clonal Casuarina equisetifolia plantation were studied.According to the obtained results,both of two pruning treatments can promote significantly the growth of H,DBH and IV.Treatment 1(pruning with 1m)and treatment 2(pruning with 2m)increased by 15.2% and 22.7% respectively than treatment 3(control,no pruning)at H,and increased by 16.1% and 14.3% respectively at DBH,and increased by 54.5%and 31.8%respectively at IV than treatment 3.In addition,both of the two pruning treatments can decrease loss of typhoon attack,but the wind-fall rate(6.5%)of treatment 2are significantly lower than that of treatment 3(33.3%).Pruning also can decrease incidence of bacterial wilt(Ralstonia solanacearum)of Casuarina equisetifoliaafter typhoon attack,but no significant difference was found among three treatments.
