京郊国营农场自五十年代起,即把制定作业规程当作一项管理制度来执行。为了使作物栽培的理论和科学试验成果形成具体措施,便于基层管理人员理解和掌握,我们从1960年一1963年就对小麦各生育期的合理长相指标与麦田管理标准进行了研究,根据对①小麦生长发育规律的定株定点观察;②灌水、施肥、播期、播量等基本措施的栽培试验;③不同产量水平麦田的总结分析;④田间问题(如黄苗、倒伏、田间整齐度)调查等总结出一套管理指标。
Since the 1950s, the state-owned farms in the suburbs of Beijing have been implementing the operation rules as a management system. In order to make the crop cultivation theory and scientific test results form concrete measures to facilitate the grass-roots managers to understand and grasp, we from 1960 to 1963 on the reasonable growth of wheat each phase growth indicators and wheat field management criteria were studied according to ① Wheat growth and development of fixed-point fixed observation; ② irrigation, fertilization, sowing date, sowing and other basic measures of cultivation tests; ③ different yield levels of wheat field summary analysis; ④ field problems (such as yellow seedlings, lodging, field uniformity) Survey summed up a set of management indicators.
