一、试验的目的播种机的工作性能是决定农业作物产量的重要因素之一。解放后几年来各国营农场先后采用了苏联制的和我国仿制的机引播种机来播种小麦和大豆。这些谷物播种机虽然基本上满足了农业生产上的需要,但无论在播种质量上和使用性能上都存在着不同程度缺陷。于是对这些播种机的工作质量进行系统的评定试验以确定他们对我国农业生产的适应性,就成为进一步发展我国农业机械化事业的重要问题之一。本试验的主要目的就是要在室内和实际生产过程中(黑龙江省),来评定几种机引 First, the purpose of the test The performance of seeder work is an important factor in determining the output of agricultural crops. In the last few years after liberation, all state-owned farms successively used the Soviet-type and China’s mock-up machine to sow wheat and soybean. Although these cereal seeders basically meet the needs of agricultural production, they have some defects in quality of sowing and performance. Therefore, it is one of the most important issues to further develop the cause of agricultural mechanization in our country that carrying out a systematic assessment of the quality of the work of these planters to determine their adaptability to agricultural production in our country. The main purpose of this experiment is to evaluate several kinds of machines in indoor and actual production process (Heilongjiang Province)
