目的探讨几种矿物材料用作空间高等植物根部基质的栽培效果 ,拟选出合适的根部栽培基质。方法在大量调研和分析的基础之上 ,选用了 4种人工合成和天然的矿物材料作为栽培基质 ;营养液通过毛细吸水材料进入栽培基质 ,植物的根部从其中获得水分和矿质营养元素 ;随后进行株高和光合作用效率等相关数据的测试与分析。结果用粗细各半的陶瓷颗粒栽培的效果最佳 ,细陶瓷颗粒较好 ,斜发沸石较差 ,麦饭石最差。结论粗细各半的陶瓷颗粒既具有良好的吸水性 ,又具有适宜的通气性 ,可以用作空间高等植物的栽培基质。
Objective To study the cultivation effects of several mineral materials on the root substrate of space higher plants, and to choose the suitable root culture substrate. Methods Based on extensive investigation and analysis, four kinds of synthetic and natural mineral materials were selected as the cultivation medium. The nutrient solution entered into the cultivation medium through the capillary water-absorbing material, and the roots of the plants obtained the water and mineral nutrients from the roots. Subsequently, Plant height and photosynthesis efficiency and other related data testing and analysis. The results with half the thickness of the ceramic particles cultivated best, fine ceramic particles are better, clinoptilolite poor, the worst stone. Conclusion The ceramic particles with half the thickness have good water absorbency and breathability, and can be used as the cultivation medium for higher plants in space.
