在推行采育兼顾伐的采伐方式中,乌敏河林业局在1965年遇到近似同龄的单层林和单层的中壮龄林以及其他林相,根据因林制宜的精神,我们分别采用了“采育兼顾伐”、“二次渐伐”、“抚育伐”以及少部份的“间伐”。对复层异龄林采用“采育兼顾伐”以林业部所规定的三条标准来控制,对近似同龄的单层林采用“二次渐伐”主要是以采伐强度一般不超过60%来控制,对于成过熟林而蓄积量较少者确定为
In implementing the harvesting and harvesting methods, the Wuminhe Forestry Bureau encountered single-layer and single-layer middle-aged forests and other forest types in similar age in 1965. According to the principle of “ The ”mining and taking care of cutting“, ”secondary tapering“, ”tending“ and a small part of the ”thinning“. The stratified anaerobic forest with ”mining and taking care of cutting “ to the three criteria set by the Ministry of Forestry to control the same age single-layer forest using ”secondary fade " mainly in the cutting strength is generally not more than 60% to control, for the over-mature forest and the accumulation of less confirmed as
