利用作物模拟模型辅助决策小麦新品种推广初探

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，通过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模拟，并与实测值进行比较，最后对品种的生态适应性进行了综合评价。最终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，试图尝试用一条新的途径，辅助

New approaches to wheat cultivars extension assisted by crop simulation model

Based on the field trial and ancestor's research and with winter wheat as study material and CERES-WHEAT model as study tool, the potential application of crop simulation model in new wheat cultivars extension was studied in this research. The purpose of this research was to apply the dynamics and prediction function of crop simulation model and predict the phonological period, the days from sowing to harvesting, yield and yield component of different wheat varieties at different sites by applying the existed variety parameter, soil data and weather data. Meanwhile the predicted values were compared with the measured value. In the end, an integrated evaluation about variety ecological adaptation was conducted. The yield performance and ecological adaptation of a wheat variety can assist the decision during the variety region trial and extension. This attempt may be a new approach to solve some problems existing in new variety extension.
