日光温室气雾培生产系统的设计
Design of aerosol-culture production system in sunlight greenhouse
摘要
Abstract
There are the problems of low environmental control accuracy, unstable production system and small planting area in the process of aerosol-culture production at present. Because of the problems advanced new technologies of aerosol-culture production can't maximize the realization of high yield, quality and efficiency. In order to solve the problems, aerosol-culture production system was studied, focusing on the reasonable illumination conditions to expand the planting area and PLC for construction of stable plant growth environment to get accurate, rapid, and flexible. Determining layout parameters of the aerosol-culture production system, optimizing the structure, form, work parameters and size parameters, determining the structure and parameters of PLC control were researched. Afterwards, aerosolculture production system in sunlight greenhouse was designed suitable for the actual production requirements. The test results showed that the each terminal pressure of the regional pipeline in regions changed within 3％; the temperature differences in the terminal cultivation beds were less than 2 ℃ ; the temperature differences of nutrient solution between in terminal cultivation bed in the each region and in the storage tank were less than 2 ℃ ; the humidity in terminal cultivation bed in the each region was less than 1％; reflux time of nutrient solution in reflux pipeline was less than 30 min; all the test indexes met the production requirements. The production system will create conditions for further promoting the application of aerosol-culture technology in facility agriculture.关键词
