Methane emission rates from rice paddies in a rural village near Beijing, China were measured during three complete vegetation periods from 1990 to 1992. Methane is produced primarily from anaerobic decay of organic matter in the paddy soil. The methane emission rate showed a strong diurnal variation which correlated closely with change in soil temperature after the tillering stage. This paper describes the results of the methane monitoring and the effects of four kinds of chemical fertilizer on the diurnal variation of methane emission flux. Several possible methane mitigation alternatives are also proposed.17 refs., 5 figs., 5 tabs.
