当前,我省西部地区各国营林场杨树低质林采伐后,在迹地伐根清理工作中,存在着“挖疙瘩难”。突出表现为人工挖疙瘩雇工难、工价高、效率低、质量差。但从国内资料上看,现有的掘根机械都是针对伐区的较大伐根设计和制造的。其作业方式是单株间断式拔根作业,用来清理“低改”迹地上较小伐根,显然是效率低、成本高。为了解决人工林采伐迹 At present, after the cutting of poplar low-quality forests in the state-owned forest farms in the western region of our province, there is a problem of “digging pimples” in the cleanup work of cutting down roots. Outstanding performance for the artificial dug pimple hired hard, high prices, low efficiency, poor quality. However, judging from the domestic data, the existing tunneling machines are all designed and manufactured for the larger section of the cutting area. The mode of operation is intermittent single root removal operation, used to clean up the “low change” traces of the small spikes, apparently inefficient, high cost. In order to solve the cutting of planted forest
