1.向大型化方向发展扩大温室的面积,有利于节省材料、降低成本、提高采光率、节省能耗和提高栽培效益。目前,国外每幢温室的面积基本上都在0.5公顷以上。连栋温室得到普遍推广,温室的栋高在4.5米以上,玻璃面积增大。温室空间扩大后,可进行立体栽培和便于机械化作业。 2.向机械化、自动化方向发展设施内部环境因素(如温度、湿度、光照度、CO_2)浓度等)的调控由过去单因子控制向利用环境、计算机多因子动态控制系统
1. To large-scale development to expand the area of the greenhouse, help to save materials, reduce costs, improve daylighting rate, save energy and improve the cultivation efficiency. At present, the area of each greenhouse in foreign countries is basically above 0.5 hectare. Multi-span greenhouses are generally promoted, the greenhouse height of 4.5 meters above the glass area increased. After expanding the greenhouse space, can be three-dimensional cultivation and easy mechanization. 2. Mechanization, automation direction The development of facilities within the environmental factors (such as temperature, humidity, light intensity, CO 2) concentration, etc.) from the control of the past single factor control to the use of the environment, the computer multi-factor dynamic control system
