摘要

这项研究探索了在农业中利用月球土壤资源的可能性。以TLS-01(泰国人造月球风化层模拟物-01)为试验物质,研究了腐殖微胶囊在提高月球培养应用物理和化学质量方面的有效性。以向日葵(Helianthus annuus L.)为试验植物。TLS-01颗粒分布均匀、整齐,由54.55%的多边形和45.45%的棒状组成,不具有高的持水能力。这些植物生长在TLS-01中,但它们的物理特性是不可接受的。与在商业种植材料中生长的向日葵幼苗相比,在TLS-01土壤中生长的葵花幼苗的发芽率、根和茎长都较低。在物理性质和养分方面有所改善后,从试验种植所用土壤与腐殖酸浓度之间的关系研究来看,没有发现土壤和腐殖酸之间的相互作用。因此,虽然土壤类型有显著差异,但腐殖酸却没有。结果表明,与商品种植材料相比,添加2倍于推荐剂量的腐殖酸的TLS-01∶椰子椰壳的1:1混合物可以提高向日葵的幼苗生长(p≤0.05),发芽率和生长指数分别为85.00%和6.62。然而,为了刺激星际应用的实际用途,椰子纤维状材料和腐殖物质被应用于微胶囊中。此外,腐殖释放试验表明,6小时后,Fickian扩散对腐殖物质的释放率为73.45%,然后有所减缓。包封率为90.37%。

Improving the Quality of Lunar Regolith Simulant Soil for Future Food Security
This research explores the possibilities of using lunar soil resources in agriculture. The effectiveness of humic micro-encapsulated was investigated for physical and chemical quality improvement for lunar culture applications by using TLS-01 (Thailand artificial lunar regolith Simulant-01) as a test substance. Sunflower (Helianthus annuus L.) was used as the test plant. TLS-01 particles were evenly distributed, uncluttered, and consisted of 54.55% polygons and 45.45% rods, without having high water-holding capacity. The plants were grown in TLS-01, but their physical characteristics were unacceptable. Sunflower seedlings grown in TLS-01 soil showed a lower percentage of germination, and root and stem length compared to those grown in commercial planting material. After an improvement in physical properties and nutrients, from the study of the relationship between the soil used in the trial for planting and the humic acid concentration, no interaction between soil and humic acid was found. Therefore, while the soil types were significantly different, the humic was not. The results showed that a 1:1 mixture of TLS-01: coconut coir with the addition of 2 times the recommended dose of humic acid could enhance sunflower seedling relative to commercial planting material (p≤0.05). The germination percentage and growth indexes were 85.00% and 6.62, respectively. However, in order to stimulate actual usage for interplanetary application, coconut fiber-like materials and the humic substances were applied as in microcapsules. Additionally, the humic release test showed that after 6 h, the release of humic substance by Fickian diffusion was 73.45% and it then slowed down. The encapsulation efficiency was 90.37%.
