中幼龄林抚育机械化工艺及机械系统探讨

加强中幼龄林抚育管理已是我国林业的紧迫任务。由于任务繁重,采用机械化抚育方式已势在必行。本文在调查研究和试验的基础上,根据地形,坡度划分三种机械化类型区,并确立制定中幼龄林抚育机械系统的4项主要因素。提出4种不同类型的抚育机械化工艺路线及可供选择的机械系统类型。建议在我国宜发展中小型机械,配合有效的手工工具,在发展机械化的同时,必须重视半机械化和工具化。实现中幼龄林抚育机械化的困难很多,可以适当地搞一些不同类型机械化抚育试验点,总结经验,全面推广。

STUDY ON MECHANICAL PROCESS AND SYSTEM OF TENDING OF CULTURE

It is emergent task to strengthen the management and tending of cultures in China forests. Based on the series of investigations and tests, the areas have been divided into three kinds according to the geography and slopes, thus the four factors have been definited about the machinery system of tending of cultures. We have put forward four processes of tending and machinery system which can be selected. We suggested that it is necessary to develop small and medium machines ,fit with efficient hand tools. While developing machinery in our country, semi-machines and hand tools should be paid attention.There will be a lot of difficulties to realize the mechanization of tending of cultures. So it is possible to set experimental area in which the machinery of tending of cultures is put in effect ,from which experiments can be summed in order to popularize in China.
