背景和目的：许多模型已被开发用于评估作物生长和发育，但很少有能够模拟葡萄藤系统。本研究进行了评估的STICS模型的能力，代表葡萄藤物候，生物量生产，产量和土壤含水量在两种情况下不同的降雨分布和水管理strategies.Methods和Results：模拟进行了灌溉葡萄园在智利和灌溉和非灌溉葡萄园在法国。作物模型给出了一个很好的估计葡萄藤物候的主要阶段（模拟值和观测值之间的差异小于6天）。土壤含水量是最好的模拟变量（R2 = 0.99），而葡萄藤蒸散量只观察到在智利（R2 = 0.43）和叶面积指数只观察到在法国（R2= 0.80）是最差的模拟变量。正确模拟生物质产量、产量及其组分（在平均观察值周围的95%学生置信区间内）。通过对土壤水分和葡萄树水势的测定值与STICS模型计算的水分胁迫指数的比较，表明STICS模型能够正确地估计葡萄藤树水分胁迫的时间和持续时间。结论：STICS模型在模拟葡萄树的生长发育和确定葡萄树水分状况的关键时期方面是相当成功的。STICS模型可用于评估各种水分管理策略及其对葡萄生产的影响。
Background and aims: Many models have been developed to evaluate crop growth and development, but few are capable of simulating grapevine systems. The present study was carried out to evaluate the ability of the STICS model to represent grapevine phenology, biomass production, yield and soil water content in two situations differing with respect to rainfall distribution and water management strategies.Methods and results: Simulations were performed for an irrigated vineyard in Chile and an irrigated and a non-irrigated vineyard in France. The crop model gave a good estimation of the main stages of grapevine phenology (less than six days difference between simulated and observed values). Soil water content was the best simulated variable (R2 = 0.99), whereas grapevine evapotranspiration observed only in Chile (R2 = 0.43) and leaf area index observed only in France (R2= 0.80) were the worst simulated variables. Biomass production, yield and their components were correctly simulated (within the 95 % Student confidence interval around the mean observed value). A comparison of the fraction of transpirable soil water and vine water potential measurements with the water stress indices calculated by the STICS model showed that the time and duration of the grapevine water stress period was correctly estimated.Conclusions: Therefore, the STICS model was reasonably successful in simulating vine growth and development, and identifying critical periods concerning the vine water status.Significance of the study: The STICS model can be used to evaluate various water management strategies and their impacts on grape production.
