摘要
Abstract
Measurement and analysis were conducted on temperature of back roof,air and soil in a greenhouse located in Shenyang Agriculture University. Based on the model of the thermal balance, applying the diathermanous theory, the forecasting dynamic thermal model of the temperature of the back roof inside greenhouse was analyzed. Nonlinear regression was conducted by Matlab software, and the parameters of this model were obtained. The model reflected the characteristics of the temperature of the back roof,and provided the foundation for forecasting the temperature change and realizing the automatic control. The model provided measures and references for researching heat preservation and realizing the control in advanced of intelligent greenhouse.关键词
