Abstract

Abstract: CO₂,N₂O and CH₄ emission from dry-land wheat ecosystem were measured by static chamber-gas chromatographic techniques in hilly area of central Sichuan Basin. The results showed that CO₂,N₂O and CH₄ emission from wheat ecosystem changed remarkably daily and seasonally. During the whole growth stage of wheat,CO₂,N₂O and CH₄ emission fluxes in different experimental treatments had significant differences. The maximal daily emission flux of CO₂ appeared at 1:00～3:00 p.m.,and the minimum volume appeared at 3:00～6:00 a.m.The emission fluxes of CO₂ were different during the growth stages of wheat. N₂O emission increased with wheat growth.Meanwhile,N₂O was emitted as follow:general nitrogen fertilizer application > no nitrogen fertilizer application > bare land. The maximal and the minimum daily changing of N₂O emerged at different time in the different growing stage. The change of CH₄ volume from dry-land wheat was not obviously related to temperature,humidity and other environmental factors.It showed that the CH₄ emission was no regular.
