| 摘 要： | 应用某日光温室青椒试验场的试验数据,以Jnesen模型为例,利用SPSS软件计算作物水分生产函数。结果表明,青椒在苗期、开花期和结果期3个生育阶段敏感指数分别为0.152、0.308、0.334。模型的拟合优度为0.75,应用F检验法对模型进行显著性检验,证明Jensen模型计算结果合理,SPSS软件计算作物水分生产函数方便可行。

| Abstract: | Crop water production function was caculated based on SPSS software , taking Jensen model as an example , through the application of a pepper testing field data in a greenhouse.The results showed that the sensitivity coefficients in three green pepper periods of seeding , flowering and fruiting were 0.152 , 0.308 , 0.334 respectively.Goodness of fit was 0.75 , significance test was carried out by using F Test , Jensen model calculation result was proved to be reasonable and crop water production function caculated by SPSS software was feasible. |
