The Physicochemical Property of Different Vegetation Materials with Cement and Mushroom Waste Compost for Hydroseeding

Abstract

噴植工法應用於崩塌裸露地，可快速植生綠化，迅速形成覆蓋，減少逕流，降低二次災損，並提供植物生長之基盤條件。本研究選擇四種波特蘭水泥比例（分別佔基材乾重比例為1％、3％、5％與7％），三種壤質砂土比例（分別佔基材體積比例為10％、20％與40％），三種菇類堆肥比例（分別佔基材體積比例為90％、80％與60％），以及對照組100％菇類堆肥，共13組試驗配方。經不同基材配方理化性分析結果，菇類堆肥80％+壤質砂土20％+水泥5％配方可有效改善原僅以菇類堆肥為生長基材之配方之理化性質，達到增進保水能力及抗沖蝕能力之功效。

The application of hydroseeding allows fast planting and greening for rapidly covering landslides and reducing runoff to decrease second damage and provide basement conditions for plant growth. The application and improvement of mixed materials are continuously developed. Total 13 test recipes are selected for this study, containing four ratios of Portland cement (with mixed material dry weight ratio of 1％, 3％, 5％, and 7％), three ratios of loamy sandy soil (with mixed material volume ratio 10％, 20％, and 40％), three ratios of mushroom compost (with mixed material volume ratio 90 ％, 80％, and 60％), and the check treatment of 100％ mushroom compost. According to the physicochemical property analysis of various mixed materials recipes, the result shows that the prescription of 80 % mushroom compost +20% loamy sand +5% cement can effectively improve the physicochemical properties of the material which were only cultivate on mushroom compost, to increase the water retaining capacity and erosion resistance efficiency.
