实现农业现代化是各国农业发展的总体趋势,近百年的世界农业发展史积累了丰富的现代化经验,也形成了多样的现代化模式。新中国成立以来,我国农业现代 Realizing agricultural modernization is an overall trend of agricultural development in various countries. Over the past century, the history of world agricultural development has accumulated rich experience in modernization and has also formed a diversified modernization model. Since the founding of New China, China’s agricultural modernization
