This study investigated the effect of vermicomposting on the degradation of rice straw and kitchen waste. Different ratios of straw and kitchen waste mixtures were used as feedstocks. After vermicomposting the substrates for 45 days under 20-25 °C moisture 60%, the vermicomposting resulted in a significant increase in phosphorous (31.38-55.89%) and potassium (33.40-63.15%), whereas a decrease was seen in TOC (38.24-43.49%) as well as TN (9.01-32.52%). The growth rate of earthworm (Eisenia foetida) was obtained in all feedstocks, the optimal rice straw/kitchen waste ratio for the earthworm growth was 3/2, excessive kitchen waste as negative impacts on the growth of earthworms. The result indicated that vermicomposting rice straw and kitchen waste with Eisenia foetida promoted nutrition content in a short period of time.
本研究探讨了堆肥对水稻秸秆和厨余垃圾降解的影响。使用不同比例的秸秆和厨余混合物作为原料。在 20-25°C、60%湿度条件下进行 45 天的堆肥后，堆肥导致磷（31.38-55.89%）和钾（33.40-63.15%）显著增加，而 TOC（38.24-43.49%）和 TN（9.01-32.52%）则减少。所有原料中均获得了蚯蚓（赤子爱胜蚓）的生长率，蚯蚓生长的最佳水稻秸秆/厨余垃圾比例为 3/2，厨余垃圾过多对蚯蚓的生长有负面影响。结果表明，用赤子爱胜蚓对水稻秸秆和厨余垃圾进行堆肥可以在短时间内提高营养成分。
