Effect of CH_4 uptake flux under different tillage systems in wheat field in the North China Plain
不同耕作措施对华北地区麦田CH_4吸收通量的影响

North China is one of the major grain producing areas in China,the calculation of the soil CH4 uptake and emission in this area play important role in estimating accurately China's emission amount of agricultural greenhouse gas and establishing reasonably agricultural mitigation and adaptation measures.In this study,the dynamic change and diurnal variation of soil CH4 flux in five tillage models during different growth periods in North China were studied using the Static-Chamber method and the Gas Chromatog...
