自七十年代以来,南方林业部门所属的一些科研、教学和生产单位,研制过一批营林机械,成果有几十个,有的成果甚至还得到了各种奖励。但是至今在生产中推广的甚少,即使原来在生产中使用的几种,也因农村经济体制的变化而被废弃了。今天我们应该深入地研究一下造成这个现象的原因,对指导我们今后的工作,是有深远意义的。下面谈谈个人一管之见,供同行参考。 Since the 1970s, some scientific research, teaching and production units affiliated to the southern forestry department have developed a number of silviculture machinery and have achieved dozens of achievements. Some have even won various awards. However, little has so far been promoted in production, even if several of the ones originally used in production have been abandoned due to changes in the rural economic system. Today, we should study in depth the reasons for this phenomenon and have far-reaching significance in guiding our future work. Here to talk about a personal opinion, for peer reference.
