| 中文摘要 | 利用静态箱/气相色谱法观测川中丘陵旱地小麦生态系统CO2、N2O和CH4的排放通量。结果表明,旱地小麦CO2、N2O和CH4排放具有明显的日变化和季节变化特征。在小麦的整个生长季中,常规、无氮、空白、裸地等实验处理的CO2、N2O和CH4的排放通量具有显著差异。CO2排放通量表现为常规>空白>裸地,CO2日最高排放值在每日13:00~15:00时出现,最低排放值出现在凌晨3:00~6:00,且作物的不同生长季CO2排放通量具有一定的差异。在小麦生长季中,N2O通量排放呈递增趋势,N2O排放通量表现为常规>空白>裸地。旱地小麦CH4通量排放和温度、湿度等环境因子不具有显著的相关性,排放无规律。 |
| 英文摘要 | CO2 , N2O and CH4 emission from dry- land wheat ecosystem were measured by static chamber- g as chromatographic techniques in hilly ar ea of central Sichuan Basin. The r esults showed t hat CO2, N2O and CH4 emission from w heat ecosystem chang ed r emarkably daily and seasonally. During the whole g rowth stage of w heat, CO2, N2O and CH4 emission fluxes in different exper imental treatments had significant differences. T he maximal daily emission flux of CO2 appeared at 1: 00~ 3: 00 p. m. , and the minimum v olume appear ed at 3: 00~ 6: 00 a. m. The emission fluxes of CO2 were different during the g rowth stages o f wheat. N2O emission incr eased w ith wheat gr owth. Meanw hile, N2O was emitted as follow : g eneral nitrogen fertilizer application > no nitro gen fertilizer application > bare land. The maximal and the minimum daily changing of N2O emerged at different time in the different growing stage. The chang e of CH4 volume fr om dr y- land wheat was not obv iously related to temper ature, humidity and other env ironmental factors. It showed that the CH4 emission w as no regular. |
