Abstract: This paper summarized regional demonstration practices and effects of new agro-technologies developed at the Luancheng Agro-Ecosystem Experimental Station of Chinese Academy of Sciences (or Luancheng Station for short) over the last 30 years. In 1978, Luancheng County was selected as one of three comprehensive experimental bases for national agricultural modernization. New technologies for greenhouse facility, rural renewable energy, straw mulching and model cultivation of winter wheat were initially imported or developed in Luancheng and extended to North China in early 1980s. The peri-urban agriculture model combined with farming, livestock, fruit and vegetable production was developed and demonstrated in the mid 1980s. The resource-saving agriculture model focused on water saving was developed and disseminated in the region in the early 1990s. The urban agriculture model with characteristic information technology and sightseeing agriculture was developed and demonstrated in the early 21 century. Luancheng Station has developed agricultural models/technologies suitable for regional agricultural modernization that adequately serve the local farmers. In the 1970s, the station launched experiments for agricultural modernization practices in China. It had led agro-technological innovations/modernization and established regional agricultural modernization models at different agricultural development stages which promoted the development of agricultural modernization in China.
