| 摘 要： | 通过对沾河林业局现有的兴安落叶松人工林抚育机械即割灌机、油锯、集材机械进行分析和研究,结果表明：国产机型与国外先进机型相比,还存在着很大的改进空间。短距离集材,畜力集材具有优势;随集材距离加大,拖拉机集材效率明显高于畜力集材。影响集材效率的关键因素是回空和重载时间。

| Abstract: | An investigation was conduct to analyze the operation efficiency of tending machines such as brush cutter,chainsaw,and skidder applied in larch plantation in Zhanhe Forestry Bureau,Heilongjiang,China.Results show that the operation efficiencies of current China-made models were lower than those of advanced foreign models and need improvement.Animal skidding has an advantage in short distance;however,with the distance increasing,the efficiency of tractor skidding was significantly higher than that of animal ... |
