中文摘要 | 針對崩塌地現行之主要噴植基材組合要項及其配比設計,分析其影響植生成效之相關問 題,進行菇類廢棄木屑堆肥(或稱太空包資材)與黏著劑之試驗,期望探討提升其基材之保水力, 並試驗基材配比對多花黑麥草(Lolium multiflorum )之萌芽率與初期生長之影響。本研究先由太 空包資材物理化學性質分析結果中,發現菇類廢棄木屑具有低酸鹼值(pH=5.24) 、高電導度(EC =3.97 mS/cm) 及高碳氮比(C/N=39.6) 等不良之情形,會對種子發芽及植物初期生長造成影 響。再進行高分子黏著劑之性質分析,並測定0.1%、0.08%、0.05%、0.03%、0.015%及0.01% 六種不同濃度之黏度,以及各濃度對於萌芽率之影響。從研究結果顯示,高分子黏著劑使用少 量時(0.01%~0.1%),就有著相當良好之黏著效益,各濃度之發芽狀況亦相當良好(皆達萌芽率 85%),其中以黏著劑濃度0.015%之發芽狀況最佳(萌芽率92%)。 |
英文摘要 | Aiming at the assembly items and the proportion design of presently major hydroseeding materials for landslides, it tends to analyze the factors in vegetation, to proceed the experiment on mushroom waste sawdust compost (or growth bag material) and adhesive, expecting to promote the waterretention capacity of the materials, and to test the effects of material proportion on the germination rate and the initial growth of Lolium multiflorum. First, it is found that mushroom waste sawdust presents low pH value (pH=5.24), high conductivity(EC=3.97 mS/cm), and high C/N ratio (C/N= 39.6) in the physical and chemical property analysis of growth bag material, which could affect the seed germination and the initial growth. Furthermore, the property of high polymer adhesive is analyzed to measure the effects of viscosity with various concentrations of 0.1%, 0.08%, 0.05%, 0.03%, 0.015%, and 0.01% and such concentrations on germination rate. The research outcomes show that a small amount of high polymer adhesive (0.01%~0.1%) could appear well favorable adhesive benefits, and the germination in various concentrations is also satisfactory (achieving the germination rate 85%), in which the adhesive concentration 0.015% appears the optimal germination (the germination rate 92%). |
