我区水稻旱种是春播旱种,即以足墒为基础,旱整地、早播种、幼苗期旱长,分蘖期后采取湿润灌溉技术为主的一种节水型种稻方式,具有省工、节能、投资少、效益高、适于机械化作业等优点,是发展水稻生产的新技术,应予足够的重视,在类似内蒙这样降水少的地区推广水稻旱种,意义尤为重要。我国北方水源不足是发展水稻的限制因素,自1983年全国农技推广总站把水稻旱种列为重点推广项目以来,现已发展到全国十三个省、市、自治区,面积达240多万 Rice cultivation in our region is a spring sowing drought species, that is, based on adequate moisture, drought and sowing, early sowing, seedling drought, tillering stage to take wet irrigation technology based a water-saving rice planting, with provincial workers , Saving energy, less investment, high efficiency and being suitable for mechanized operation. It is a new technology for developing rice production. Attention should be paid enough to popularize rice dry cultivation in areas with less precipitation such as Inner Mongolia. Therefore, it is particularly important. Inadequate water supply in northern China is a limiting factor for the development of rice. Since 1983, when the National Agricultural Technology Extension Station listed dry cultivation of rice as a key promotion project, it has now developed to more than 2.4 million of the 13 provinces, municipalities and autonomous regions in the country.
