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.
In this study, by using regression design method, this paper discussed the measurable technical measures of spring wheat in the groundwater of Yanbei area in Shanxi Province - the relationship between the number and period of irrigation, sowing amount, farmyard manure and nitrogen and phosphorus fertilizers and spring wheat yield and economic income Point experiment, obtained the mathematic model of ecotypes of different wheat fields.The optimal scheme proved to be practical and gaining certain economic benefits through the demonstration comparison and small-area extension in 1986 and 1987.
