摘要: Methane fluxes from Beijing ricefields as affeced by organicamendment, water regime, crop establishment method, and rice cultivarwere measured with a closed chamber method in 1990, 1991, 1995, and1996. Total fluxes from plots receiving high organic amendment alwaysexceeded those fromthe low-input plots. Compared with continuousflooding, intermittent irrigation (there were a feew days of nostanding water between two irrigations) and constant moisture (thefield had no standing water, but remained saturated) reduced methaneemission rate by 25.4 and 58.4/100, respectively
