摘要： 本研究用回归设计方法，探讨了山西省雁北地区水地春小麦可定量技术措施--灌水次数和时期、播种量、农家肥及氮磷化肥与春小麦产量和经济收入的关系。经1985年多点试验，获得了不同麦田生态型的数学模型。优选方案经1986和1987年的示范对比和小面积推广，证明是切实可行的，获得一定经济效益。

Abstract: With a regression design this study deals with the quantitative technical measures irrigation frequency and dates,weight of seeds sown per hectare,(rate of seeding),application of manure and chemical nitrogen and phosphorus fertilizers in relation to the yield of spring wheat grown in irrigated fields in the Yanbei Prefecture of Shanxi Prowince and financial income.Through multipoint test,various mathematical models of eco-systems of wheat fields have been obtained.After application on a small scale and comparison in 1986 and 19g7,the optimization plans proved to be feasible and profitable.
