【摘要】：為明確堆肥過程中溫室氣體和氨氣排放規(guī)律以及產(chǎn)生的總溫室效應,在云南省大理州開展堆肥試驗,并以奶牛糞便為試驗材料,研究了農(nóng)民堆肥(FC)、覆蓋堆肥(CC)、覆蓋-翻堆堆肥(CTC)和覆蓋通風-翻堆堆肥(CATC)4種堆肥方式對溫室氣體和氨氣排放的影響。結果表明:覆蓋通風-翻堆堆肥(CATC)可提高堆肥腐熟度,有效降低CH4和N_2O排放,但并沒降低CO2和NH_3排放;與農(nóng)民堆肥(FC)相比,覆蓋堆肥(CC)的CH4排放量增加了48.7%,而N2_O和NH3排放量與農(nóng)民堆肥(FC)基本一致;覆蓋-翻堆堆肥(CTC)雖然提高了腐熟度,但CH_4、CO_2和NH_3排放量較大;堆肥結束時,4個處理的總溫室效應分別為25.6、32.9、38.1及18.0 kg/t;溫度與CH_4、CO_2、N_2O和NH_3排放速率均極顯著相關,pH值顯著影響N_2O和NH_3的排放。因此,覆蓋通風-翻堆堆肥(CATC)不僅能夠滿足堆肥產(chǎn)品的腐熟度要求,而且能夠減少總溫室效應,再加上其操作簡便,能夠在生產(chǎn)中推廣應用。
[Abstract]:In order to clarify the emission rule of greenhouse gas and ammonia gas and the total Greenhouse Effect produced during composting, the composting test was carried out in Dali Prefecture, Yunnan Province, and cow dung was used as the test material. The effects of four composting methods, including FC, CC, CTC and CATC, on greenhouse gas and ammonia emissions were studied. The results show that CATC can increase compost maturity and reduce CH4 and N2O emissions, but not CO2 and NH3 emissions, compared with farmers' composting (FC), CATC can effectively reduce CH4 and N2O emissions, but not reduce CO2 and NH3 emissions, compared with farmers' compost (FC), CATC can effectively reduce the emission of CH4 and N2O. The CH4 emission of CC increased 48.7, while the discharge of N2O and NH3 was basically the same as that of farmer compost (FC), although CTC increased the maturity of compost, the emission of CH4CO2 and NH3 was larger. At the end of composting, the total Greenhouse Effect of the four treatments were 25.6o32. 9kg / t and 18.0 kg / t, respectively, and the temperature was significantly correlated with the CH4CO2C / N2O and NH3 emission rates. The pH value of the four treatments significantly affected the emission of N2O and NH3. Therefore, CATC can not only meet the requirements of maturity of compost products, but also reduce the total Greenhouse Effect. Besides, it is easy to operate and can be widely used in production.
