发展农业机械化应能带来明显的经济效果,这不仅从理论上说应当是推行农业机械化不可违背的根本原则,也早已为国内外大量成功的实践所证实。但从黑龙江省三十年来的农业机械化的历程来看,许多县和社队并未因推行机械化都获得应有的经济效果。从全国来看也大致如此。主要原因是:国民经济有关部门配合不够,同农业生产发展有些割裂,某些农机产品供应同需要脱节和投放机器不注重经济核算等等。归总起来就是一条:从特定条件出发研究农业机械化发展的自然规律和经济规律不够。特别是没有认真把农业机械“化”的科学研究开展起来。农业机械“化”科学技术体系的主要内容可归纳为:农业机器系统、农业生产能源、农机化经营管理、农机化技术推广服务和农机化技术经济五方面。建议用“农业机械化工程”这一新学科名称来概括。通过农业机械化工程的研究,可以为我们社会主义国家提供积极干预农机化事业发展的科学依据,逐步走出一条中国式的农业机械化道路来。针对我们是社会主义国家和人均自然资源较少,工农业技术和经济基础都比较薄弱等情况,我国农业机械化道路应具有以下主要特点:搞农业机械化要给每个农业劳动力安排出路;要搞以增产为主要目标的能源节约型的机械化;机械化资金要社队自力更生与国家资助相结合,要采? The development of agricultural mechanization should bring about obvious economic results. This should not only theoretically be an indispensable principle in the implementation of agricultural mechanization, but also confirmed by the large number of successful practices at home and abroad. However, judging from the history of agricultural mechanization in Heilongjiang Province over the past three decades, many counties and communes and brigades have not obtained the due economic benefits due to the implementation of mechanization. This is also true from the national point of view. The main reason is that the cooperation between the relevant departments of the national economy is not enough, and the development of agricultural production is somewhat fragmented. The supply of certain agricultural machinery needs to be disconnected from the supply and the machines are not paid attention to economic accounting. To sum up is one: starting from a specific condition to study the development of agricultural mechanization of the natural laws and economic laws are not enough. In particular, scientific research that fails to “agriculturalize” agricultural machinery has been carried out. The main contents of agricultural machinery science and technology system can be summed up in five aspects: agricultural machinery system, agricultural production energy, management and operation of agricultural mechanization, technical extension service of agricultural mechanization and technical economy of agricultural mechanization. It is recommended to use the name of “Agricultural Mechanization Engineering” to summarize. Through the study of agricultural mechanization projects, we can provide our socialist countries with a scientific basis for actively intervening in the development of agricultural mechanization and gradually come out of a Chinese-style agricultural mechanization road. In view of the fact that we have less natural resources in the socialist countries and per capita and relatively weaker industrial and agricultural technologies and economic fundamentals, the road to agricultural mechanization in our country should have the following main features: Engage in mechanization of agriculture to give every agricultural labor force a way out; Increase production as the main goal of energy-saving mechanization; mechanization of funds to the community self-reliance and national funding combined, to be taken?
