摘　　要：试验通过对不同配方甘蔗渣堆肥腐熟进程的"C/N比值"变化特征分析及堆肥后的基质的理化性状的测定,筛选出适宜的育苗基质配方。结果表明:基质配方6#、7#在理论上最为理想,即以地面堆沤方式,粪肥占堆体积的10%或者每立方米加入1 kg尿素,C/N比值在15～20,且能满足育苗需要的理化性质要求。理想配方的容重在0.5～0.8 g/ml范围内,总孔隙度70%～90%,持水孔隙度不低于50%。The experiment to get the most suitable substrate formula was carried out by analyzing the characteristics of ＂C/N ratio＂ in different formula of bagasses compost and physicochemical properties of bagasse compost. The result showed that formula 6# and 7# were the best in theory by the mean of corn- posting on the ground in the condition of experiment, composted with 10% manure or with lkg urea in 1 m3 pile, ＂C/N ratio＂ ranged between 15 and 20, and two formulas could meet the seedling growth need of physicochemical properties. The ideal formula was named as unit weight was 0.5-0. 8g/ml, total po- rosity was about 70% and 90% , and water holing capacity was not less than 50%.
