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 investigate the cultivating effects of several mineral matters used as root-zone media for higher plant growth in space. Method Four kinds of artificial and natural mineral matters were used as plant root-zone media based on lots of investigation and analysis. Nutrient liquid was delivered into the media by a long capillary material, and roots of plants obtained nutrition and water from the media. The related parameters such as plant height and photosynthetic efficiency were measured and analyzed. Result The growing effect in a mixture of coarse and fine ceramic particles with equal quantity proportion was the best, that in fine ceramic particles was the second best, that in clinoptilolite particles was the third and that in diorite particles was the last. Conclusion The mixture of coarse and fine ceramic particles with equal quantity possesses not only fine capillary action, but also good aerating ability, and therefore is capable of being utilized as an effective root-zone media for higher plants intended to be grown in space.
