摘要: 运用混合线性模型和MINQUE(1)法对作物栽培试验非平衡资料进行分析,揭示了生态环境效应、处理组合与生态环境互作效应对作物产量等目标性状的影响;解决了长期困惑作物栽培试验的非平衡资料分析问题,为估算生态环境随机效应量开辟了新途径.

Abstract: With mixed linear model and MINQUE(1) method, the unbalanced data from crop culture experiment were analyzed, and the effect of ecological environment and its mutual effect with treatment combination on yield and other objective traits were revealed. The long term perplexed problem in analyzing unbalanced data from crop culture experiment was solved, and a new approach for estimating the stochastic effect of ecological environment was developed.
