In order to solve the problems of weak single green control ability and poor application effect of model assembly in the cultivation of green rice in the cold area of north China. Using the demonstration and promotion methods of core area, radiation area and conventional area. The effects of different green cultivation modes on grain yield, quality and economic benefit were discussed. The results showed that, compared with the conventional planting area, the grain yields of the core area and radiation area were relatively low, and the difference between the conventional planting area and the core area reached a significant level; the content of functional elements magenesium, selenium and zinc in grain in the core area and the radiant area were significantly increased, and the quality of rice, especially the processing quality was improved; the economic benefits of the core area and the radiation area were significantly improved by 17 682 RMB/hm2 and 5 670 RMB/hm2 than the conventional planting area. The green cultivation mode is suitable for the promotion of rice in cold areas of north China.
