The effects of different additives on the compost of Camellia oleifera shell were characterized and a maturity evaluation system for the obtained compost was established. Four treatments were designed as C. oleifera shell with C. oleifera seed meal (A1), with C. oleifera seed cake (A2), with sheep manure (A3), and with spent mushroom substrate (A4). A3 had the longest thermophilic phase (over 50 °C) and shortest cooling phase. Compared with A1, the thermophilic phase of A2 was postponed 11 days due to the high lipid content, but terminated almost at the same time. The temperature of A4 increased slowly and took longer time to reach ambient. C/N, pH, E4/E6, and NH-N decreased along with composting process, while TN, GI, and NO-N were opposite. Based on the Pearson correlation analysis with the Solvita maturity index as a reference, the result indicated that TN, C/N, GI, NH-N, and pH can be used for the maturity evaluation.
研究了不同添加剂对油茶果壳堆肥的影响,并建立了获得堆肥的成熟度评价体系。设计了四种处理方式,分别为油茶果壳与油茶籽饼(A1)、油茶籽粕(A2)、羊粪(A3)和废菌棒(A4)。A3 的高温期(超过 50°C)最长,冷却期最短。与 A1 相比,由于 A2 中的高脂质含量,其高温期推迟了 11 天,但几乎在同一时间结束。A4 的温度上升缓慢,达到环境温度所需的时间较长。C/N、pH、E4/E6 和 NH-N 随着堆肥过程而降低,而 TN、GI 和 NO-N 则相反。基于与 Solvita 成熟度指数的 Pearson 相关分析作为参考,结果表明 TN、C/N、GI、NH-N 和 pH 可用于成熟度评价。
