Methane emissions from rice-oil cropping paddy fields and its total measurement packed column
Methane emissions from paddy fields in rice oil rotation and its total measurement packed column Details:

Name: Packed column
Specification: 2m*3mm
Model: TDX-01

In the three years of experimental research from 1995 to 1997, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used static box method and gas chromatograph to sample and measure methane emissions from rice fields with different water management methods in the ** area, 1996 It also carried out the reception of satellite remote sensing data (TM and NOAA-AVHRR data) from the ground experimental base at the same time as in 1997 on a sunny day. based on the measured methane emission flux from the rice field and the rice planting area extracted with remote sensing data, the regional scale was estimated The total amount of methane emissions from rice fields in the past three years shows that the rice planting area in the ** area is 17.72 12 × 10 4 hm2, and the average methane emission flux from the rice fields is 2.984 mg/(m2 · h). The emission amount is 0.02 0 3Tg/a. The influencing factors of methane emission from rice fields are analyzed by gray correlation method, and a model for estimating methane emission flux from submerged rice fields with rice vegetation index as a parameter is established.
