The Study on Related Model for Water Evaporations and Environmental Factors under Different Soil in Greenhouse
Evapotranspiration is the fundamental basis for the study of greenhouse water balance and the planning of irrigation. In this paper, based on the analysis and experimental data, the result is that the evaporation of soil water was mainly affected by the indoor temperature, indoor humidity and indoor lighting. Among three environmental factors such as the indoor temperature, indoor humidity, indoor light and evaporation of soil water, the regressions analysis was done. In this study, through the experimental observations of soil water evaporation, variation characteristics for soil water evaporation and quantitative relationship among the climatic factors have been analyzed under the conditions of greenhouse microclimate in summer. Quantitative relationship tested with data for experimental observations. Therefore, only based on the indoor lighting, the determination for the fertilizer and water irrigation index is not accurate. And the impact of indoor humidity should also be considered. The study was done in order to provide a theoretical basis in the environmental optimization of modern greenhouse fertilizer and water irrigation management control in summer.
