摘要
收集2018年8—9月塑料大棚内观测的气象数据,构建了基于线性逐步回归的草莓生产大棚内的地温预测模型,采用1号大棚内的地面温度、气温、风速、总辐射,构建1个模拟方程,在构建的过程中,逐一剔除不显著的自变量。将通过信度为0.05水平的显著性检验的要素模拟出地温模型。通过2号棚的相应数据验证模型。该模型所需参数少,实用性强,模拟精度较好,可为设施夏季草莓气象服务和环境调控提供数据依据。
Collected meteorological data observed in plastic greenhouses from August 2018 to September 2018,and constructed a ground temperature prediction model for strawberry production greenhouses based on linear stepwise regression.A simulation equation was constructed using the ground temperature,air temperature,wind speed,and total radiation in greenhouse 1,and insignificant independent variables were removed during the construction process.The elements that have passed the significance test with a reliability of 0.05 level should be simulated into the ground temperature model.Then validate the model using the corresponding data from shed 2.This model requires fewer parameters,has strong practicality,and good simulation accuracy,which can provide data basis for strawberry meteorological services and environmental regulation in summer facilities.
