Optimization on the Effect Parameters of Greenhouse Environment on the Growth of Tomato

Tomato is one of the major vegetables in greenhouse production.Putting maximize the tomato fresh weight as control objective.So it could create favorable microclimate parameters and conditions to fit crop growth and development.The influence of parameters of microclimate(temperature,relative humidity,light intensity)upon the tomato fresh weight and optimum parameters of microclimate system were studied in this paper.The experiment results showed that the most important factor affecting tomato fresh weight was temperature,relative humidity,light intensity.The optimized combination of factors was temperature 24℃,relative humidity 80% and light intensity 17.2 klx.
