摘 要: | 目的]探究猪粪堆肥过程中调理剂的配比及养分变化情况。方法]猪粪与水稻秸秆的质量比在4:1、6:1、10:1的条件下,研究3个处理(①:120kg猪粪+30k稻草;②:135.0kg猪粪+22.5kg稻草;③140kg猪粪+14kg稻草)的温度、pH值、TN、TP、TK等理化指标的变化情况。结果]3个处理的温度维持在50℃以上的时问分别为4、10、3d,最高温度分别达到51.0、57.0、60.5℃,在第25天时,3个处理的总养分含量分别达到11.33%、12.07%和13.19%。pH值分别上升至8.73、9.00、8.79。结论]以猪粪和水稻秸秆的质量比为6:1时,混合腐熟的效果最佳。

Abstract: | Objective ] The study aimed to research mixture ratio of conditioners and variation of nutrient in the process of pig manure composting maturity. Method] In the conditions of proportions of pig manure and rice straw were 4: 1,6: 1, 10: 1, the change of temperature, pH, TN,TP,TK of three treatments ((1): 120 kg pig manure + 30 kg rice straw; (2): 135.0 kg pig manure + 22.5 kg rice straw; (3): 140 kg pig manure + 14 kg rice straw) were studied. Result ] The results showed that the highest temperatures three treatments were 51.0, 57. 0, 60.5℃. The time maintaining above 50 ℃ were 4, 10, 3 d. the contents of main nutrition (N + P2O5 + K2O) were 11.33% , 12.07 and 13.19% at 25th day. The pH value of three treatments all increased and reached 8.73, 9.00 and 8.79 respectively. Conclusion] Pig manure and rice straw proportion 6:1 was best for composting maturity. |
