我场于一九七二年开始从事研制双轮驱动,单体四连杆仿型的双轴内旋苗间除草机。后因该机型结构复杂、制造困难、作业中故障较多等因素而淘汰。七三年又重新研制了一种单盘转子无动力苗间除草机。七四年样机在二队梳苗一万一千亩大豆,基本上能满足农艺要求,年终梳过苗的大豆亩产达280.6斤。通过该队七年来的应用,证明只要调正合理,运用正确,效果还是很好的,二队大豆平均单产都超过二百斤,三年上了纲要。并且,
I started in 1972 in the field of research and development of two-wheel drive, single four-link profile of the two-axis rotary seedling weeding machine. After the model because of the complex structure, manufacturing difficulties, more failures and other work out. In seven or three years and re-developed a single disc rotor unpowered seedling weeder. Seven or four prototypes in the second team combed 11,000 acres of soybeans, basically to meet the requirements of agronomic, year-end combed seedlings of soybean per-mu reached 280.6 kg. Through the application of the team over the past seven years, it has been proved that as long as the adjustment is correct and the application is correct, the effect is still very good. The average yield of the second team soybeans exceeds two hundred jin and three years has passed. and,
