Analysis of Heat and Humidity in Single-Slope Greenhouses with Natural Ventilation

A single-slope greenhouse (SSG) is the general name of a kind agricultural facility widely used in China. Microclimate studies for SSGs Weifang, Shandong Province, are relatively scarce. This paper mainly discusses test data nine including temperature, humidity, solar global radiation intensity, CO2 concentration, wind speed, and vapor pressure deficit (VPD) trend. Moreover, conservation quality method to estimate ventilation volume humidity growth after opening top vent greenhouse. Through analysis this paper, local SSGs, internal environmental change has commonality but its environment still influenced by many factors, such as plant planting density, cover, height, time. In addition, can provide quantitative tool calculating controlling researchers workers basis strategies.
