小麦栽培科学的发展趋势是提高单产、省工节本、优质高效,逐步实现栽培区域化、技术措施规范化、生长发育指标化、模式化,促使传统栽培向模式化栽培转化。我国在应用电子计算机,通过数学模拟对作物生育与栽培措施进行优化预测与调控的研究方面已取得了初步进展,但仅仅是起步。为了配合小麦高产农艺模式化研究,将技术单元组装配套,进行了综合农艺选优的研究。本试验采用多元回归旋转设计,在同品种的基础上,对播期、密度、肥料三个主要因素进行综合试验,通过电脑运算,建立数学模型,优选 The development trend of wheat cultivation science is to increase yields, save time and cost, achieve high quality and efficiency, gradually realize cultivation regionalization, standardization of technical measures, indexization and pattern of growth and development, and promote the transformation from traditional cultivation to model cultivation. China has made some initial progress in applying computer science to optimize the prediction and regulation of crop growth and cultivation through mathematical simulation. However, it has just started. In order to meet the high yield agronomic model of wheat, the technical unit assembly supporting, carried out comprehensive agronomic optimization research. In this experiment, multiple regression rotation design was used. On the basis of the same breed, the three main factors of sowing date, density and fertilizer were comprehensively tested. The mathematical model was established through computer operation,
