低芥酸油菜栽培模型及其优化的初步研究

Preliminary Study on Cultivation Models and Its Optimization of Low Erucic Acid Rape (B.napus)

本文采用农业系统分析法对低芥酸油菜栽培农艺措施中五个主要的可控因子进行了模式化、定量化研究,并进一步优化和解析了所获得的产量模型,提出了一套普适性栽培方案.最后,将各目的性状模型,按文中所分析的产量及经济产量优化方案、因子主效应、单因子与产量的关系,边际产量效应,因子交互作用等结论,综合形成栽培决策系统,为生产提供参考.

By use of .means of systematic analysis, a quantitative and modelled research on agronomic measures of low crucic acid rape (B. napus) production one red soil hill land was made, and as -a result, a set of quadratic regressive models were obtained and put in the experimental cultivation. In confirmation of these modles, further optimization and analysis was made on yield model, and summed up a universal design, which intigrated the factors of economic yield, dominant effect, marginal yield effect and their interactions so as to form a cultivation system of low erucic acid rape production.
