日光温室的集雨灌溉与沼气增温增二氧化碳技术

Water and Energy Saving Technology for Chinese Solar Greenhouses

针对我国目前日光温室等设施农业的特点和发展现状,讨论了我国日光温室的节水节能技术的应用与发展方向,这些技术包括温室棚面集雨灌溉和利用沼气给日光温室加温以及利用沼气为改善作物发育环境而补充二氧化碳。提出了集雨设施的合理配套、沼气池池容与日光温室的合理配套以及温室提高二氧化碳环境浓度对温室节水的意义。

Based on current installation of agriculture specialties in China such as Chinese solar greenhouses and their developing actuality, this article discusses application and developing way of water-and energy-saving technology for solar greenhouse, which covers rainfall collection system of greenhouse roof, methane warming for greenhouse and improving CO2 environment by methane. The paper submits the proper integrity of rain-fall collection facility with solar greenhouse, the fitness of methane tank volume to solar greenhouse size and the significance of enhancing environ-mental CO2 concentration in greenhouse for greenhouse water-saving.
