Of Chongqing Three Gorges Reservoir Area Facilities, The Cultivation Of Greenhouse Cooling Systems

The paper points out that a great gap exists on the technique of greenhouse cooling between different regions on analyzing its development in and out of the country. The technique of greenhouse cooling is more developed in the north area of China; the corresponding installations, facilities and management techniques mainly aim at the nature and weather condition in the north. Currently, the installation cultivation technique of Chongqing Three Gorges Reservoir has already shown promising trend of development with the application of West Exploit strategy, agricultural structure adjustment and the improvement of people's living standards, and the extrovert agriculture's higher demands on the products. However, the facilities and techniques are mainly introduced from the north and abroad. Due to the various geographical climates, applying the same mode is evidently unconscionable. Therefore, according to the unique weather condition of Chongqing Three Gorges Reservoir, it is of great significance to study its project and management techniques in a broad view.The main objective of the paper is to selectively assemble the facilities which are fit for Chongqing Three Gorges Reservoir greenhouse cooling. The main research contents include: first, to research comparatively and assemble the facilities which are fit for Chongqing Three Gorges Reservoir greenhouse cooling. Second, it is to study the relationship between the main factors of facilities cultivation environment of Chongqing Three Gorges Reservoir.The technical route adopted in the paper is: selecting and confirming the research base; collecting materials; field-examining the changing law of temperature factors; studying comparatively and selectively assembling the facilities of the greenhouse cooling; proposing the research report.The key technique of the paper is to study comparatively and assemble the facilities which are fit for Chongqing Three Gorges Reservoir greenhouse cooling.The corresponding achievement:The plan of selectively assembling installations and facilities of the main temperature factors has been proposed. The following cooling ways are studied: Ventilation cooling, Water curtain-wind machine cooling, Sun-shading cooling.In modern greenhouse, two or more ways are adopted at the same time to improve the cooling effect and reduce power waste, e.g. sun-shading and water curtain-wind machine cooperate, spray cooling and water curtain-wind machine are adopted together, etc.Based on theory analysis and experiment, the paper discusses the greenhouse cooling effect and put forward the many kinds of the better plans for the greenhouse...
