生草覆蓋下有機(jī)無機(jī)配施對(duì)蘋果園溫室氣體排放的影響
發(fā)布時(shí)間:2021-06-06 11:14
農(nóng)業(yè)活動(dòng)對(duì)溫室氣體的排放貢獻(xiàn)很大,特別是CO2、CH4和N2O,主要通過捕獲地球發(fā)出的長(zhǎng)波輻射來影響氣候變化。本研究旨在監(jiān)測(cè)果園有機(jī)無機(jī)配施條件下這3種重要溫室氣體(GHGs)的排放量。本試驗(yàn)以陜西省渭北區(qū)白水縣西北農(nóng)林科技大學(xué)蘋果試驗(yàn)站為試驗(yàn)地點(diǎn),研究了生草覆蓋與有機(jī)肥、化肥配合施用對(duì)蘋果園溫室氣體排放的影響。試驗(yàn)設(shè)置生草覆蓋(R)和無覆蓋清耕(C)兩種主處理,副處理為:不施肥(CK),用化肥(NPK)、有機(jī)肥(M),MNPK化肥結(jié)合有機(jī)肥(MNPK)。采用靜態(tài)箱采氣法和氣相色譜儀收集測(cè)定CH4、N2O和CO2的排放通量。通過研究油菜覆蓋結(jié)合有機(jī)無機(jī)肥的施用,研究了生草覆蓋對(duì)蘋果園溫室氣體(GHGs)排放的影響。本研究結(jié)果發(fā)現(xiàn),油菜覆蓋栽培系統(tǒng)的溫室氣體排放量(GHGs)明顯高于清耕處理。1.各處理CO2排放量季節(jié)變化一致,CO2排放通量與土壤含水量、溫度呈極顯著正相關(guān)。生草覆蓋處理下的平均CO2
