摘要
目的为未来的空间站受控生态生保系统中高等植物栽培筛选合适的照明光源。方法在空间高等植物栽培地面实验装置中进行 ;利用红蓝两种发光二极管的四种不同组合制成的灯箱作为照明光源 ;利用多孔管和多孔陶瓷颗粒无土栽培技术培养。结果红色发光二极管下生长的植株初期呈匍匐状 ,后期直立、细长 ;红色和蓝色发光二极管组合下的植株生长基本正常 ,但 90 %红色发光二极管 + 1 0 %蓝色发光二极管组合下植株的综合指标最佳。结论植株正常生长可采用红色和蓝色发光二极管的一定组合 ,以 90 %红色 + 1 0 %蓝色发光二极管更为适宜。
Objective To select suitable light source for higher plant cultivation in the controlled eclological life support system of the future space station. Method The experiment was carried out in the Space Higher Plant Cultivation Ground-based Experimental Facility(SHPCGEF); four combinations of two red and blue light-emitting diode(LED) were utilized as light sources; soilless cultivation technique with porous ceramic tubes and porous ceramic particles was utilized in the growth system. Result The plants grown under the shelf of pure red LED showed a lying-down state in early stage, and stood erect in later period with slender and long stems; the plants under various combinations of red and blue LED grew with nearly normal state, but the plants under the combination of 90% red and 10% blue LED possessed the best comprehensive indexes. Conclusion The normal growth and development of plantlets needs two light sources of red and blue LED, and the combination of 90% red and 10% blue LED is the optimum one among those tested combinations.
