Our research showed that the closed transplant production system with artificial light and controlled environments is suitable for producing high quality transplants in a reduced time period with reduced resource and environmental pollution. The production period could be reduced by 30%. The water consumption in the closed was about 10% of that of open system (i.e. greenhouse). Percentage of COィイD22ィエD2 fixed by transplants through photosynthesis over COィイD22ィエD2 supplied into the closed system was about 90%. Energy consumption per transplant was about 0.4 MJ and its cost was about 1.5 Yen. This cost is relatively low compared with the price of vegetable transplants (50-100 Yen). Then, the closed system with artificial lighting can be used for commercial production of value-added transplants. More research is needed for examining the physiological responses of transplants to environments and the energy/mass balance of the closed system.

研究表明，采用人工光照、环境可控的封闭式移栽生产系统，适合于在较短的时间内生产出高质量的移栽，减少资源和环境污染。生产周期可缩短30%。封闭式温室耗水量约为开放式系统(即温室)的10%。移栽植株通过光合作用固定COィイD22ィエD2的比例高于供给封闭系统的COィイD22ィエD2的比例约为90%。每次移植的能耗约为0.4MJ，成本约为1.5日元。与蔬菜移植的价格(50-100日元)相比，这一成本相对较低。然后，带有人工照明的封闭系统可以用于增值移植的商业生产。需要更多的研究来检验移植物对环境的生理反应和闭合系统的能量/质量平衡。
