摘要: 本研究采取不同比例的波特兰水泥、壤质砂土、菇类堆肥, 以及对照组100%菇类堆肥配方, 共13组试验配方, 于各基材配方中分别添加多花黑麦草及相思树等种子进行室内发芽试验, 探讨不同比例的基材配方对于植物种子发芽的影响, 为喷植工法资材应用效益提供佐证与参据。试验结果表明, 各试验配方多花黑麦草种子发芽率仍达85%以上, 显示植物种子发芽受水泥比例影响不显著;团粒湿筛稳定分析及保水力中比较, 以菇类堆肥90%+壤质砂土10%+水泥7%配方的抗冲蚀性和28d加水后含水量为最高, 为各试验配方中最佳, 发芽率亦达90%以上, 对于植物种子发芽均能达到较佳效果。Abstract: The study is application and improvement of mixed materials for continuous development on landslide in Taiwan.Total 13test recipes are selected for this study, containing four types of Portland cement, three types of loamy sandy soil, three types of mushroom compost, and the control group of 100% mushroom compost.From the test results, the germination percentage of Lolium multiflorum with various recipes reaches up to 85%, revealing that the seed germination is not significantly affected by cement ratio.In the comparison of aggregate stability analysis with wet-sieving and water retention, the erosion resistance of the recipe of mushroom compost 90% + loamy sandy soil 10%+cement 7% appears the highest water content after adding water for 28days that it is the optimal recipe.The germination percentage also achieves more than 90% that it is regarded as the best mixed material in this study.
