水稻栽培技术路线、模式表与回归数模配套应用的研究

针对安徽省水稻产量结构的薄弱环节与主要技术障碍,提出高产优质高效的栽培技术路线.以此路线为纲,拟订“模式表”,选定供试栽培技术因子,多点同步进行“模式表”应用验证和正交旋转组合设计试验,供试因子零水平与其它栽培条件力求与“模式表”保持一致.试验数据经统计分析求得“回归数模”,模拟选优并参考示范验证结果修订“模式表”.“栽培技术路线指明了主要栽培技术目标和措施;在供试5项栽培措施方面“回归数模”可以指导“模式表”的灵活应用;按“模式表”栽培既可以确保“技术路线”的具体实施,又可以为“回归数模”的应用创造必要的条件.

STUDY ON APPLICATION OF ROUTE OF CULTIVATION TECHNIQUES,MODEL TABLE AND REGRESSION MODEL OF RICE

In accordance with weak link and main technical obstacles of rice yield composition in Anhui Province,We put forward the route of cultivation techniques with high yield,top quality and best efficiency in this paper.We worked out a model table and elected factorsof cultivation techniques for experiments based on the route.At the same time,both applica-tion and verification of model table were conducted with the design of quadratic orthogonalrotation combination on several experimental sites,adopting the factors of experiment as zerolevels and keeping both the factors and other cultivated conditios in line with the modeltable.Obtaining the negression model by statistical analysis for the data,the model table wascorrected in imitating optimization and refering to the results of field demonstration.Theroute of cultivated techniques indicated the main aim and measures for cultivated techniques.The regression model can guide flexible application for model table in the five cultur-mea-sures for experimentsAclording to the model table for the cultivation,the route of techniques can be guaranteed to put into effect and the necessary conditions were created for application of regression model.
