占农业用水65%的水稻用水大户,由于缺水严重而影响水稻产量的稳定和提高。如今,科技人员以节水、高产、优质、高效、低耗为目标,从多种方法中找出了水稻节水增产新途径。目前,此项新技术已在黑、吉、辽、冀、蒙、陕、宁、新、鲁、豫、苏、湘、鄂、浙、赣、沪、渝、川、黔等19个省、市、区推广开来。3月29日,源于“九五”国家重中之重的粮食增产综合技术大面积推广项目在北京通过专家鉴定,以卢良恕院士为首的专家委员会认为,“水稻节水增效技术”在20年的研究、开发、推广应用的历史上经受了考验。科技人员发现,19个省、市、区的水稻种植区域广阔,地区气候差异大,不宜用同一节水技术模式。用生物节水、农艺节水、化学节水、工程节水、管理节水,形成综合节水栽培系统工程。还把多元化节水措施进行集成、组装配套,培育出抗旱性强的健壮秧苗,同时再改革稻田耕作方式,以提高资源利用率和产出率。实践证明,一些低洼易涝和盐碱区,一些不适合种旱作物和经济作物的
Large water users, who account for 65% of agricultural water use, have a serious impact on the stability and improvement of rice production due to severe water shortage. Nowadays, with the goal of water saving, high yield, high quality, high efficiency and low consumption, scientists and technicians have found out a new way for saving water and increasing yield of rice from various methods. At present, the new technology has been applied to 19 provinces and autonomous regions including the Heilongjiang Province, Jilin Province, Liaoning Province, Hebei Province, Mongolia, Shaanxi Province, Ningxia Province, Shandong Province, Henan Province, Jiangsu Province, Hunan Province, Hubei Province, Zhejiang Province, Jiangxi Province, Shanghai Municipality, City, district to promote open. On March 29, a large-scale popularization project for grain production technology that originated from the “95” national priority passed the expert appraisal in Beijing. The expert committee led by Academician Lu Lian-shu holds the view that the technology of rice water saving and efficiency enhancement "In 20 years of research, development, promotion and application of the history of the test. Science and technology personnel found that 19 provinces, cities and districts have a vast rice planting area and large regional differences in climate. They should not use the same water-saving technology mode. With biological water-saving, agronomic water-saving, chemical water-saving, water-saving projects, water-saving management, the formation of a comprehensive water-saving cultivation systems engineering. In addition, diversified water saving measures are integrated, assembled and matched to cultivate robust seedlings with strong drought resistance, and at the same time, the cultivation methods of paddy fields are reformed to improve resource utilization and output rate. Practice has proved that some low-lying floods and salina areas, some are not suitable for crops and cash crops
