2、驗(yàn)前期排放速率較大,中后期排放較少:NzO在試驗(yàn)前期排放速率較小,后期排放速率逐漸上升;牛糞不同堆放方式對溫室氣體排放的影響很大,除了夏季試驗(yàn)堆放高度50cm和25cm處理CI-L的排放速率差異不顯著之外,其他處理間溫室氣體的排放差異都顯著,兩個季節(jié)中每天加糞10kg處理c0:和cH。的排放速率較大,其他處理co:和CH。的排放速率較??;N20的排放速率基本表現(xiàn)出相反的趨勢。綜合溫室效應(yīng)每天加糞10kg處理的最大,堆放高度為50cm處理的最小。關(guān)鍵詞:奶牛糞便;溫室氣體;堆放方式中圖分類號:X511文獻(xiàn)標(biāo)識碼:A
