小麦精密播种早在70年代就被农学家试验证实是高产之路,但一直没有好的机具。我厂1988年从中国农机院北京农机化所引进了2BJM 型小麦精密播种机专利技术,取得了成功。1989年我厂在秋播前生产了1050台2BJM 型小麦精播机,全部销售一空,精播小麦180万亩,每亩平均省种5千克,共节省良种约900万千克。若按每千克良种售价1.4～2.0元计,共节约资金1260万元,每亩增产根食50千克,共增产粮食9000万千克,社会效益十分可观。
Precision wheat sowing was proven to be a productive road by agronomists as early as the 1970s, but there has been no good machine. I plant in 1988 from the China Agricultural Machinery Beijing Agricultural Machinery introduced 2BJM precision wheat sowing machine patented technology, and achieved success. In 1989, our factory produced 1050 2BJM wheat precision seeding machines before the autumn seeding. All the sells were sold out. The seeding wheat was 180 million mu. The average saving 5 kg per mu was saved about 9 million kilograms. If the price per kilogram seeds 1.4 ~ 2.0 dollars, a total savings of 12.6 million yuan, 50 kilograms of root yield per acre to increase production of grain 90 million kg, social benefits are impressive.
