不同种类有机肥施用对一季稻田CH4排放的影响
The Effect of Different Organic Manures Treatments on Methane Emission from Single-cropping Paddy Fields
摘要
Abstract
Methane emission fluxes from single-cropping paddy fields with application different fertilization treatments were studied by using the static chamber-gas chromatograph techniques with manual method. Results showed that the treatments with application fertilizer increased methane emission compared with no fertilizer treatments (NF). Seasonal average methane emission flux of the incorporation of rice straw and mineral fertilizer( RS) was 31.04 mg·m-2·h-1 which increased by 326.4%( P<0.05) and 211.7% compared with that of the mineral fertilized MF) and incorporation of pig manure and mineral fertilizer( PM), respectively. Seasonal average methane emission flux from the incorporation of chicken manure and the mineral fertilizer( CM) increased by 140.4%( P<0.05) and 75.7%(P<0.05) as compared with MF and PM, respectively. The results indicated there was the obvious influence for RS and CM to methane emission. However, there was no significant difference between NF and PM. According to the analysis of related environmental factors, there was significant correlation between methane emission fluxes and the soil temperature at S cm depth, and the same as the soil Eh. No significant correlation was found between CH4 flux and water depth. The unit yield of Global warming Potential (GWP) in PM treatment was 0.83 kg·kg-1 which suggested PM was a better recommend fertilization during the rice growth. The application of PM took the slight advantages not only in reducing the GWP but also in improving the grain yield.关键词
