Abstract
A multipurpose operating system was developed to adjust both spray times and ventilation method without a configuration of the moving path and the type of the greenhouse. The multipurpose working system proved to be a reliable system for testing the growth quality of the fruit vegetables in the greenhouse. The results are as follows. The first leaf, diameter of a stem, leaf area, and average stem diameter in the Cucumber seedling growth were repressed by high-speed ventilation, but was not repressed by spray times. The first leaf in the Tomato seedling growth was repressed as ventilation velocity was high, but the average stem diameter was not repressed. While the Tomato was given water three times a day, the diameter of a stem and the leaf area were increased as ventilation speed became higher. However, those were different other factors. The Tomato leaf area was larger when given water twice a day than that in hand spray, but showed no difference with ventilation speed. The first leaf, the diameter of a stem and the leaf area of a Red pepper were lower in automatic spraying with ventilation than those in hand spray.
