Teak Stump Sprouting Capacity Under Compound Coppice Regime Process

ABSTRACT This work aimed to evaluate the teak stump sprouting capacity under compound coppice process. The experiment was implemented at spacing of 3.0 × 2.0 m and 3.0 × 3.0 m. At 8-years old, the experiment was systematically thinned in 50%. After thinning, with new spacing of 3.0 × 4.0 m and 3.0 × 6.0 m, the stump sprouting capacity of the thinned trees was evaluated. The experimental design used was randomized blocks, whit two treatments and 5 repetitions. The treatments were T1 = conduced sprouting under compound coppice process at the spacing 3.0 × 4.0 m and T2 = conduced sprouting under compound coppice at the spacing 3.0 × 6.0 m. Teak presented sprouting capacity under compound coppice until 12-years old for both treatments.

摘要 本研究旨在评估复合矮林作业模式下柚木伐桩的萌芽能力。试验初始种植株行距设置为3.0×2.0 m与3.0×3.0 m。林分生长至8年生时，对试验林开展50%强度的系统性疏伐。疏伐完成后，保留木株行距调整为3.0×4.0 m与3.0×6.0 m，随后对疏伐后留存木的伐桩萌芽能力进行评估。试验采用随机区组设计，设置2个处理与5次重复。处理组T1为株行距3.0×4.0 m下采用复合矮林作业模式的萌芽培育，T2为株行距3.0×6.0 m下采用复合矮林作业模式的萌芽培育。两种处理模式下，柚木在12年生以内均具备复合矮林作业下的萌芽能力。
