为解决北方寒地绿色水稻栽培生产中存在的单一绿色防控能力弱和模式组装应用效果差等问题,采用核心区、辐射区和常规区示范推广方式,探讨了不同绿色栽培模式对水稻产量、品质和经济效益的影响。结果表明,与常规种植区相比,核心区与辐射区水稻产量要低,其中核心区差异达显著水平;功能性元素镁、硒、锌含量显著提高,稻米加工品质改善;经济效益显著提高,核心区和辐射区较常规区经济效益分别增加17 682元/hm²和5 670元/hm²,且核心区稻米符合A级绿色产品标准。可见,绿色栽培技术模式是适于寒地水稻推广的一种模式。

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.
