土壤微循環氣體采集系統——AGPS
AGPS可野外無人值守自(zi)動(dong)采集(ji)土壤(rang)表(biao)(biao)面(mian)(mian)氣體。采集(ji)時箱(xiang)蓋自(zi)動(dong)平移并閉(bi)合到(dao)土壤(rang)表(biao)(biao)面(mian)(mian),隔膜泵(beng)抽取土壤(rang)表(biao)(biao)面(mian)(mian)氣體,自(zi)動(dong)分(fen)裝(zhuang)到(dao)20ml樣品瓶中,以便(bian)后續(xu)對CO2、CH4、NO2等各(ge)種(zhong)氣體成分(fen)進行實驗(yan)室分(fen)析(xi)檢驗(yan)。采集(ji)間隙,箱(xiang)蓋自(zi)動(dong)平移打開,土壤(rang)保(bao)持自(zi)然暴露狀態。
