摘要
１９９１～１９９３年在乾县中南部灌区，通过采用高产优质品种、实行“三密一稀”种植、科学配方施肥、建立合理群体结构及科学管理等综合配套技术，３年累计开发吨粮田２．０７万ｈｍ￣２，达标１．３９万ｈｍ￣２，产量达１５ｔ／ｈｍ￣２以上。试验证明，吨粮田的建设与开发是大幅度提高粮食产量、促进农村经济发展的战略措施，对解决人多地少、人增地减、粮食匮乏的社会问题有深远意义。
During the period of 1991～1993 in the irrigated area in the mid-south ofQianxian County,the comprehensive perfection techniques of the rational populationstructure and scientific management were established through the adoption of high-yield,fine-quality crop varieties, the practice of“3- close and 1-sparse plantings”,andthe application of scientifically prescribed fertilizers,Within 3 years 20.7 thousand hm￣2 of one-ton- permu grain field were developed,13.9 thousand hm￣2 of them reached thetarget requirements with the yield of over 15 t/hm￣2.The experiment has proved that theconstruction and development of one-ton- permu grain field are a strategical measure toincrease grain yield to a great extent and to promote economic development in the coun-tryside;they also have a profound and lasting significance for solving the social prob-lems of large population with short land,growing population with decreasing arableland,and food shortage.
