小麦高产、优质、规范化栽培数学模型研究初报

本试验利用旋转设计测得参数,建立起冬前苗情、产量、品质的回归模型。通过计算机模拟筛选了亩产500公斤以上的农艺组合方案,并对各农艺措施的单因素效应或交互效应进行了分析,找到了亩产425～475公斤是高产优质栽培的适宜区间,同时筛选出在这个产量范围内提高品质的农艺组合方案,为实现高产优质规范化栽培提供了科学依据。

THE FIRST REPORT ON THE RESEARCH OF MATHEMATICAI MODEL ABOUT THE STANDARDIZED CULTIVATION FOR THE HIGH OUTPUT AND GOOD QUALITY OF THE GRAINS OF WINTER WHEAT

This artical is the regressive models about the cases of the seedlingsbefore the overwintering time. Yield and quality of winter wheat grainsthat are formed in the light of the parameters that are obtained by meansof the rotative regressive design on the basis of the former cultural tech-nical standard of the high yield of winter wheat grains at Huang County. Through the analogy of computer, it is screened out that is thecombined agricultural plan over 500kg per mu grain yield, and analysedthe effect of single factor or each other on every agricultural measure;and discovered the suitable range of the cultivation of high output andgood quality that is 425-475kg per mu, and in the meantime we screenedout the combined agricultural program that can improve the quality ofwheat grains in the range.Consequently,this artical provided the scien-tific basis for the standardized cultivation on the high output and goodquality of wheat.
