摘要： 为探明薰衣草秸秆堆肥的最佳碳氮比及原料配比工艺参数，设置20、25、30、35 4个碳氮比梯度，依据物料设置6种原料配比方案，精油秸秆、干花秸秆、羊粪干重比分别为0:1:9(T1=20)、1:0:0(T2=25)、0:1:1(T3=25)、0:1:0(T4=30)、2:18:1(T5=30)、1:1:0(T6=35)，探究不同碳氮比处理对堆肥过程中温度、含水率、pH、发芽指数及腐熟度与养分品质等指标的影响。结果表明，T3处理较其他处理升温较快，高温期持续时间较长，其次为T1处理；T6、T5处理高温期维持时间较短，T2、T4处理未达到高温期标准。堆肥过程中各处理含水率均呈现下降趋势，结束时T3处理含水率最低(28%)，显著低于其他处理(P<0.05)；T3处理酸碱度最低(pH 7.9)，显著低于其他处理；T1处理电导率最高，与其他处理不具有明显差异。养分品质方面，T3处理的全氮含量和有机质含量最高，T5处理全磷含量显著高于其他处理，T6处理的全钾含量最高。此外，T2、T3、T5处理的种子发芽指数极显著高于其他处理。T3、T6处理达到国家有机肥腐熟标准。综合评价表明，T3处理的综合评价值最高，腐熟程度最高，腐熟品质最优。

Abstract:

To determine the optimal composting process parameters for lavender straw, based on 4 carbon-to-nitrogen ratio gradients of 20, 25, 30 and 35, 6 different raw material ratios were set according to the material. Lavender straw, dried flower straw and sheep manure were respectively composted at dry weight ratios of 0:1:9 (T1=20), 1:0:0 (T2=25), 0:1:1 (T3=25), 0:1:0 (T4=30), 2:18:1 (T5=30) and 1:1:0 (T6=35). The effects of different carbon-to-nitrogen ratio treatments on temperature, moisture content, pH, germination index, and quality during the composting process were investigated. The results showed that the T3 treatment had a faster temperature rise and a longer duration of high-temperature period compared to other treatments, and T1 treatment followed; T6 and T5 treatments had a shorter duration of high-temperature period, while T2 and T4 treatments did not reach the standard of high-temperature period. The moisture content during the composting process generally showed a downward trend; at the end of the composting process, the moisture content of T3 treatment was the lowest (28%), significantly lower than other treatments (P<0.05); T3 treatment had the lowest pH (pH 7.9), significantly lower than other treatments; T1 treatment had the highest electrical conductivity, with no significant difference comparing to other treatments; T3 treatment had the highest total nitrogen content and organic matter content; T5 treatment had significantly higher total phosphorus content than other treatments; T6 treatment had the highest total potassium content. The seed germination index of T2, T3 and T5 treatments was significantly higher than other treatments. According to the National Organic Fertilizer Maturity Standard, T3 and T6 treatments met the national standards. The comprehensive evaluation showed that the comprehensive evaluation value of T3 treatment was the highest, the maturity degree was the highest, and the maturity quality was the best.
