我省小麦、玉米的机械化生产沿袭传统的耕、种工艺,耕、耙、播单独进行,造成了农机具型号多、作业效率及机具利用率低等缺点。为此,省科委下达我所研制与50马力级拖拉机配套的玉米、小麦耕播联合作业机任务。两年来,完成了样机的设计、试制和性能测试,並经过大面积的玉米、小麦耕、播试验和生产考核(播 The mechanized production of wheat and corn in our province followed the traditional methods of farming, planting, cultivation, raking and sowing alone, resulting in many shortcomings such as the large number of farm machinery, low operating efficiency and low utilization of machinery. To this end, the Provincial Science and Technology Commission issued by me to develop and 50-horsepower tractors supporting corn, wheat plowing joint operations tasks. In the past two years, the prototype design, trial production and performance testing have been completed. After a large area of ​​corn, wheat cultivation, sowing test and production evaluation
