Abstract:
Objective To develop the volume adjustable vegetable facilities and meet the demands of research on the growing technique of vegetables.Methods Three series of adjustable volume vegetable facilities were developed with light and ventilation module,growth module,cultivation tray module and measurement module.Telescopic structure was adopted in the facilities and the performance testing and characteristics analyses were carried out.Results The facilities could be adjusted at the height range of 250-700 mm.Three kinds of LED lights and replaceable cultivation tray and matrix were installed in the facilities.The parameters including water content,electric conductivity and temperature in the matrix,CO2 concentration in the atmosphere of facilities were monitored.The test results showed that the performances and the indexes of facilities met the subsequent experimental demands.Conclusion Light weight,small volume,and adjustable volume vegetable facilities were developed.The production efficiency of lettuce(12 plants/0.12 m2)grown in the facilities was 49.7 g(FW)plant-1.The development of facilities laid the foundation of construction of on-orbit vegetable facility.
