摘要
以青椒为试验材料研究在日光温室中青椒的水分生产函数。试验将青椒的生育期分为苗期、开花着果期、结果期3个阶段,以土壤体积含水率作为灌水控制指标。采用回归分析方法和SPSS数据分析应用软件,分别分析了现有的国际上应用广泛的Jensen模型、Stewart模型、Singh模型3个水分生产函数模型。从敏感系数、模型的拟合优度、残差平方和和F检验结果方面来看,Jensen模型所得到的结果最符合青椒的水分生产函数,其敏感系数苗期、开花着果期、结果期分别为0.152、0.308、0.334。
This paper studied and presented on water production function of pepper in greenhouse under furrow irrigation.The whole growing season of pepper was divided into 3 stages of seedling period,flowering and fruiting period.Irrigantion intervals was based on the measured soil moisture content in this research.Both regression analysis method and SPSS software were used to respectively analyze the widely-used models in the world：Jensen model,Stewart model and singh model.According to the performance of sensitive coefficient,goodness-of-fit of model,squared residuals and Ftest,the Jensen model went well along with the pepper water-use relationship,and seedling,flowering and fruiting period of the sensitive coefficients were 0.152,0.308,0.334 respectively.
