旱稻生产比水稻生产至少节约50%以上的水资源,并可避免或减少旱灾损失,有利于节约能源和减少环境污染。种植旱稻不仅可以节约水资源,还可缓解因过度灌溉产生的土壤盐渍化,减少水土流失,产生生态效益。推广旱稻其社会经济效益是综合的,可同时缓解水资源、粮食和生态三大瓶颈问题
Upland rice can save at least 50% more water than rice production, avoid or reduce drought loss, save energy and reduce environmental pollution. Upland cultivation can not only save water resources, but also alleviate soil salinization caused by over-irrigation and reduce soil erosion, resulting in ecological benefits. The promotion of Upland rice is a comprehensive social and economic benefits, which can alleviate the three major bottlenecks of water resources, food and ecology
