Abstract:

In order to do the microclimate forecast, the author used the observed data of the cucumber greenhouse which seated in Shouguang City, Shandong from 2007 to 2010, and analyzed the change rules and distribution of microclimate that in greenhouse, such as temperature, humidity and soil temperature under different weather types in winter and spring. The author used statistical method to choose the factors and built simulate models for next 24 h temperature forecasting. According to different months, different weather types and different time in a day, the simulation results were good except the April. Exam models of forecast temperature in greenhouse with observed data and weather forecast of February to May in 2010, and results were good; models could be used in microclimate factor forecast.
