90年代第一个金秋,我们怀着喜悦的心情迎来了《农牧与食品机械》(原名《农机情报资料》)创刊20周年。攀然回首,确如当初所希望的那样,本刊已在农机科研人员心目中有举足轻重的影响。这不仅有作者和编者的心血和汗水还有各级领导和广大读 In the first autumn of the 1990s, we ushered in the 20th anniversary of the founding of “Agriculture, Animal Husbandry and Food Machinery” (formerly known as “Information on Agricultural Machinery”) with joy. Looking back, it is as true as we had hoped, this journal has already had a pivotal influence in the minds of agricultural machinery researchers. This not only has the hard work and sweat of the authors and editors but also leads and broadly reads at all levels.
