中文摘要	为探究膜下滴灌条件下灌水量和土壤温度对新疆不同深度土壤CO_2浓度的影响。采用桶栽试验,通过气相色谱仪监测,研究不同滴灌水量〔充分灌溉(CK,100%);轻度水分亏缺(W1,80%);重度水分亏缺(W2,60%) 〕处理下(植棉和裸土) 10 ~ 50 cm土层土壤CO_2浓度变化规律。结果表明:灌水量对土壤剖面CO_2浓度影响显著。在植棉或裸土条件下,随着灌水量的增加,不同深度处土壤CO_2浓度均呈上升趋势,土壤剖面CO_2浓度均呈上低下高的分布特征,50 cm处CO_2浓度是表层10 cm处CO_2浓度的2倍左右,植棉土壤CO_2浓度是裸土土壤CO_2浓度的2倍左右。土壤剖面CO_2浓度变化有着明显的日变化和季节性变化规律。在一天内,土壤温度和土壤剖面CO_2浓度随气温升高而增加,呈现出单峰曲线变化规律,峰值出现在16:00;棉花生育期内土壤剖面CO_2浓度在花铃期达到最大值。灌水量和土壤温度均与土壤剖面CO_2浓度呈显著正相关(P <0.01) 。这一结果可为干旱区棉花种植节水减排提供理论参考。
英文摘要	This study aimed to explore the effects of irrigation volume and soil temperature on soil CO_2 concentrations at different depths under drip irrigation in Xinjiang.The barrel test was used with different amounts of drip irrigation:full irrigation (CK) of 100% irrigation,mild water deficit (W1) of 80% irrigation,and severe water deficit(W2) of 60% irrigation.The variation in CO_2 concentrations in the 10-50 cm soil layer were monitored and studied using gas chromatography in planted cotton and bare soil.The results showed that the amount of irrigation had a significant effect on the soil profile CO_2 concentration.Under the condition of cotton planting or bare soil,with an increase in the amount of irrigation,the soil CO_2 concentration increased at different depths,and the soil profile CO_2 concentration was characterized by an upper,lower,and higher distribution.The CO_2 concentration at a depth of 50 cm was about twice that at a depth of 10 cm in the surface layer,and the concentration of CO_2 in the cotton-planted soil was about twice the concentration of CO_2 in bare soil.The change in CO_2 concentration in the soil profile showed evident diurnal and seasonal variation.In one day,the soil temperature and soil profile CO_2 concentration increased with the increase in temperature,showing asingle peakcurve,with the peak appearing at 16:00.The soil profile CO_2 concentration during the cotton growth period reached a maximum during the flowering period.Irrigation quantity and soil temperature were positively correlated with the soil profile CO_2 concentration (P <0.01).This result provides a theoretical reference for water saving and emission reduction in cotton planting in arid areas.
