摘要：

为促进芦笋秸秆资源化利用，通过加入不同比例的鸭粪和稻壳于芦笋秸秆中，进行资源化堆肥效果的试验研究。以发酵温度、pH、发芽指数、有机质、氮、磷、钾等为评价指标，研究鸭粪和稻壳添加对堆肥发酵过程的影响。结果表明：单一芦笋秸秆堆肥发酵过程，无高温阶段，未能达到发酵堆肥要求。添加不同比例的鸭粪和稻壳均能促进芦笋秸秆堆肥发酵，高温维持时间12~13 d，高温阶段平均温度为56.3~60.4℃，发酵周期21~29 d，发酵30 d结束时，发芽指数达到了92%~118%，pH>8.0，有机质含量50.70%~57.02%，氮磷钾总养分含量4.64%~5.20%。综合各项指标，在本试验条件下，70%芦笋秸秆+10%鸭粪+20%稻壳粉的配比发酵效果优于其他配比，更适合芦笋秸秆发酵。

Abstract:

To promote the resource utilization of asparagus straw, the experimental study on the resource composting effect of asparagus straw was carried out by adding duck dung and rice husk in different proportions. The fermentation temperature, pH, germination index, organic matter, nitrogen, phosphorus and potassium were used as evaluation indexes to study the effect of adding duck dung and rice husk on composting fermentation process. The results showed that the fermentation process of asparagus straw alone failed to meet the requirements of the fermentation compost without high temperature stage. Adding different proportions of duck dung and rice husk could promote compost fermentation of asparagus straw. The high temperature maintenance time lasted for 12-13 days, the average temperature of high temperature stage was 56.3-60.4℃, and the fermentation time was 21-29 days. At the end of 30 days of fermentation, the germination index reached 92%-118%, pH>8.0, organic matter content reached 50.70%-57.02%, total nutrient content (i.e. N + P2O5 + K2O) reached 4.64%-5.20%. Comparing all indexes, under the condition of this experiment, the fermentation effect of 70% asparagus straw + 10% duck dung + 20% rice husk was better than that of other ratios, which was more suitable for asparagus straw fermentation.
