摘要

由於屏東科技大學校園面積廣大，除草所產生之雜草(草屑)可視為校園的廢棄物，其體積和重量相當龐大且分解週期長，為目前廢棄物不易處理的廢棄物。在台灣主要以機械和人工方式清除，清除後再處理與再利用的相關文獻仍然很少。
本研究主要以破碎後的雜草混和副資材添加物與迴流菌種(少量腐熟堆肥)，以50：20：30之比例混合進行傳統堆肥法，副資材添加物的種類有：米糠、木屑、稻殼與豆粕，針對物理、化學及生物分析結果進行比較。在溫度、含水率、pH 、C/N比及發芽率的變化結果顯示，米糠堆肥於50℃以上高溫持續12天為最久，醱酵期間含水率皆有控制在50~70%之間，而各堆肥pH值皆為8.0以下；在化學分析部分，只有米糠堆肥之C/N比19.9，達到文獻堆肥腐熟界定範圍；發芽率測試結果顯示，各堆肥之成品發芽率皆達到90％~100%，已符合文獻建議應大於90％之腐熟標準。
本研究結果顯示，米糠堆肥於堆肥化過程中已達腐熟，且與各堆肥相較下腐熟程度為最佳。

The National Pingtung University of Science and Technology campus area, and weeding the weeds (grass clippings) can be regarded as the campus waste. However, the campus waste volume and weight are quite huge and decomposition long cycle, which becomes one of the present processing problems. In Taiwan, mainly mechanical and manual removal. Clear after the treatment and reuse literature is still very small.
In this study, the broken weeds mixed deputy materials and reflux bacteria(a small amount of compost). Mixed in the ratio of 50:20:30 of traditional composting. Deputy materials: rice bran, sawdust, rice husk and soybean meal. The variation of temperature, moisture content, pH, C/N and germination ratio, showed that the regulation above 50℃ high temperature with rice bran compost for 12 days long. The moisture content shows that the during fermentation has control in 50 to 70 percent. The regulation pH value is below respectively 8.0. In the chemical analysis part, only rice bran compost C/N ratio 19.9, reaching journal of compost maturity defined range. The germination rate test results showed that the germination rate of the finished compost are 90% to 100%, in line with the literature suggests which should be greater than 90% of the maturity standard.
The study has shown that, rice bran compost range in the composting processing has reached maturity. Maturity degree of compost compared to the best.
