水稻是国际公认的营养价值和经济效益均较高的高产粮种,原产于亚热带。随着人类生产的日益发展和科学技术的不断进步,水稻的栽培品种在各种复杂的生育环境条件下逐步得到改良,其栽培区域也从历史划定的极限地一再北移,目前我国水稻栽培已由南方暖地推进到北纬50度的黑龙江畔。黑龙江省地处寒地稻区的北部边陲,水土资源丰富,发展水稻生产潜力很大。为全面系统地总结寒地稻区多年来在水稻科研、生产上取得的各项成果和经验,使之形成适合寒地稻区特点的栽培体系,黑龙江省农科院邀请省内20多位水稻专家、学者,共同编写了《寒地稻 Rice is an internationally recognized high-yielding grain with high nutritional value and economic benefits, native to the subtropical zone. With the continuous development of human production and the continuous improvement of science and technology, rice cultivars have been gradually improved under various reproductive environment conditions. The cultivation areas have also moved north and south repeatedly from the limit of historical delineation. At present, Has been promoted by the southern warm to 50 degrees north latitude Heilongjiang River. Heilongjiang Province is located in the northern margin of the cold paddy rice region, rich in soil and water resources and has great potential for developing rice production. In order to comprehensively and systematically summarize the achievements and experiences made in the scientific research and production of paddy rice over the years and make it a suitable cultivation system for the characteristics of the paddy region in cold region, Heilongjiang Academy of Agricultural Sciences invited more than 20 rice Experts, scholars, co-wrote the "Cold Paddy
