Experimental Study of Economic Optimization in Greenhouse Cucumber

Put maximize the greenhouse input/output 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 greenhouse input/output and optimum parameters of microclimate system were studied in this paper.The experiment results showed that the most important factor affecting greenhouse input/output was temperature and the important order of factors was temperature,relative humidity,light intensity.The optimized combination of factors was temperature 31℃,relative humidity 85% and light intensity 16 klx.
