摘  要：
在田间试验和前人研究的基础上,以比较成熟的CERES-WHEAT模型为研究工具,以我国的主要作物小麦为研究材料,探讨了作物模型在区域试验和良种评价方面的潜在应用。目的在于应用作物模型的动态性和预测性功能,利用品种已有生理和遗传参数以及各地的气象、土壤资料,对冬小麦不同品种同一地点和同一品种不同地点的生育期、物候期、产量和产量构成因素进行预测,并与实测值进行比较,最后对品种的生态适应性进行综合评价,并在品种产量表现和生态适应性等方面为品种区域试验和良种推广提供决策的依据。辅助指导和决策河北省小麦新品种引进、试验和推广,提出了作物模拟模型辅助决策小麦新品种推广的应用模式。

摘  要：
Based on the data from field trial, new wheat varieties extension assisted by crop simulation model was studied. In this paper, six wheat varieties were also examined at five sites by using CERES-WHEAT model. After we inputting variety genetic parameter, soil parameter and weather data, CERES-WHEAT model was run to predict the phonological period, growth duration, yield and yield components of the six wheat varieties at five sites. Meanwhile the predicted values were compared with the measured values. Finally an integrated evaluation about variety ecological adaptation was conducted. The yield performance and ecological adaptation of a wheat variety can assist the decision in the course of the new variety extension. In addition, the author brought forward the application model of new wheat variety extension assisted by crop simulation model, which may be a new approach to cut down the cost and accelerate the new variety extension.
