温室番茄光合作用模拟模型的验证

摘要

对作物模型的验证是模型走向推广和应用的前提.利用山西农业大学设施实验基地温室的试验数据,对已建立的温室内番茄群体光合作用模拟模型进行了检验,结果表明,模型群体光合速率的实测值(0值时除外)与模拟值的相对误差在0～10.0%之间,具有良好的模拟精度,可以很好地预测环境因子对番茄生长发育的影响.%The verification is the precondition of the promotion and application of crop simulation model. Utilizing the test data of greenhouse in Shanxi Agriculture University, the canopy photosynthesis model of greenhouse tomato was evaluated. The simulation result showed that the relative error of photosynthetic rate between observed value (except for 0) and simulated value was 0 ~ 10.0%. The model had good consistency and could predict the effects of environmental factor on tomato growth.
