【摘要】 【目的】研究不同添加物对尾菜堆肥腐熟及养分的影响。【方法】以白菜、芹菜为原料，以玉米秸秆、羊粪为添加物，设置8个处理，A（纯白菜，对照）、B（白菜+25%秸秆）、C（白菜+25%羊粪）、D（白菜+40%羊粪）、E（纯芹菜，对照）、F（芹菜+25%秸秆）、G（芹菜+25%羊粪）、H（芹菜+40%羊粪），研究不同处理对堆肥腐熟和养分变化的影响。【结果】纯尾菜和添加25%羊粪的处理（A、C、E和G）始终属于厌氧状态，添加25%的秸秆和40%羊粪的处理（B、D、F和H）均处于好氧堆肥状态。堆肥结束时，除对照外其余处理均达到堆肥腐熟标准；所有处理的有机质含量分别为37.06%、66.19%、56.48%、61.37%、54.71%、71.96%、67.88%和67.20%，总养分含量分别为6.08%、4.64%、3.92%、4.8%、6.29%、4.26%、3.92%和4.67%。不同处理的碳损失表现为A>B>C>D,E>F>G>H，氮损失表现为A>C>D>B,E>G>F>H。【结论】添加物能促进尾菜堆肥腐熟和减少碳氮损失，添加25%秸秆和40%羊粪的处理效果较好。更多还原

【Abstract】 【Objective】 The study aimed to clarify the effects of different additives on compost maturity and nutrients of vegetable wastes.【Method】 Chinese cabbage and celery were used as raw materials,and corn straw and sheep dung as additives; and eight treatments were set up,which were denoted by A(Chinese cabbage,control),B(Chinese cabbage + 25% corn straw),C(Chinese cabbage + 25% sheep dung),D(Chinese cabbage + 40% sheep dung),E(Celery,control),F(celery + 25% corn straw),G(celery + 25% sheep dung) and H(celery + 40% sheep dung),respectively,in the experiment on compost maturity and nutrient changes.【Result】 The treatments of vegetable wastes and adding 25% sheep dung(i. e.,A,C,E,and G) were always anaerobic,and the treatments of adding 25% corn straw and 40% sheep dung(i. e.,B,D,F,and H) were in the state of aerobic composting. At the end of composting,all treatments except the control reached the maturity standard of composting. The organic matter contents of all treatments were 37. 06%,66. 19%,56. 48%,61. 37%,54. 71%,71. 96%,67. 88% and 67. 20%,respectively,and the total nutrient contents were 6. 08%,4. 64%,3. 92%,4. 8%,6. 29%,4. 26%,3. 92% and 4. 67%,respectively. The carbon losses of different treatments were ranked in the order as follows:A>B>C>D,E>F>G>H,and the nitrogen losses were A>C>D>B,E>G>F>H.【Conclusion】 The additives used in the study could promote compost maturity of vegetable wastes and reduce carbon and nitrogen losses,and the additions of 25% corn straw and 40% sheep dung had much better effects.更多还原
