水稻是我国主要粮食作物,约占粮食总产的40%,稻米是口粮消费的主体,消费量占口粮消费量的60%左右。人口增加和耕地减少是我国的基本国情,随着我国粮食消费需求呈刚性增长,稻谷供需总量将长期偏紧。所以,水稻生产不仅担负着确保我国粮食安全的重任,还肩负着实现种粮增效、稻农增收和全面推进新农村建设的重大使命,也是新阶段我国农业和农村经济发展的中心任务之一。黄淮稻区光热水资源充裕,环境优良,水稻灌浆期与当地最佳气候相适应,昼夜温差大,比较
Rice is the main food crop in China, accounting for about 40% of the total grain output. Rice is the main part of the consumption of rations, accounting for about 60% of the total consumption. The increase of population and the reduction of arable land are the basic national conditions in our country.

Therefore, not only is rice production responsible for ensuring food security in our country, but it is also shouldering the major mission of increasing grain output, increasing incomes of rice farmers and comprehensively promoting the new rural reconstruction. It is also one of the central tasks of our country’s agricultural and rural economic development in the new phase . Huanghuai paddy area abundant hot and cold water resources, the environment is good, the rice filling period and the best local climate adaptation, temperature difference between day and night, compare
