小麦、玉米、棉花是华北地区的三种主要作物,这三种作物的机械化是当前生产中迫切需要解决的问题。本文总结了近年来华北地区这方面的群众技术革新经验。对经过大面积生产实践行之有效的,予以了肯定,对目前尚存在问题的,也较明确地作了分析归纳,以使广大群众所创造的分散的、但是具有无限生命力的经验,集中为较系统的技术措施,用于生产,促进科研。这件事实说明,农机科研工作者只要认真按照党所指引的方向,把自己的工作与蓬勃发展的群众技术革新运动相结合,虚心向群众学习,他们是有着无限广阔的天地的,他们是大有作为的。我们相信,随着科研人员思想进一步革命化,今后一定会踊现出更多象这样来自群众,来自生产的好文章。 Wheat, corn and cotton are the three major crops in North China. The mechanization of these three crops is an urgent problem to be solved in current production. This article summarizes the mass technological innovation experience in this area in North China in recent years. It is affirmed that what has been done through large-scale production practice has been affirmed. At present, there are still some problems that have been analyzed clearly and concisely so that scattered but unlimited vitality experiences created by the broad masses of people are concentrated in the More systematic technical measures for the production and promotion of scientific research. This fact shows that as long as the agricultural scientific research workers seriously follow the direction of the party and combine their work with the thriving masses’ technical innovation movement and humbly learn from the masses, they have a vast and open world, and they are promising of. We believe that with the further revolutionization of the scientific research personnel’s thinking, more good articles like this from the masses and from production will surely be revealed in the future.
