采用静态箱-气相色谱法对不同灌溉方法(滴灌、沟灌)及相应施肥管理下的葡萄园土壤CO_2和CH_4排放进行了原位观测。结果表明,2012年与2013年生长季之中,不同灌溉方法显著影响葡萄园土壤CO_2和CH_4的排放。以滴灌替换沟灌后,2012年CO_2与CH_4减排量分别达到(3 530.34± 1 611.97) kg/(hm~2 ? a)和(0.392±0.424) kg/ (hm~2 ? a),2013年则分别达到(2 198.43 ± 713.97) kg/(hm~2 ? a)和(0.136 ±0.192) kg/(hm~2 ? a),且2012年与2013年不同灌溉处理间CO_2排放量均差异显著;若将宁夏全区沟灌葡萄园全部改造为滴灌葡萄园,则2012年和2013年GWP减排总量(以CO_2计)将达到7 077.14万kg与4 402.58万kg。滴灌能有效抑制土壤CO_2与CH_4的排放损失,更具温室气体减排潜力。 |

The situ observation was conducted by using the static chamber-gas Chromatograph technique to observe the soil CO_2 and CH_4 emissions under drip irrigation and furrow irrigation. The results showed that,during the growing seasons in 2012 and 2013,soil CO_2 and CH_4 emissions were significantly affected by different irrigation methods in the vineyard. Compared to furrow irrigation, the annual CO_2 and CH_4 emissions reductions under drip irrigation reached (3 530.34±1611.97) kg/(hm~2 ? a) and (0.392±0.424) kg/(hm~2 ? a)in 2012,and (2 198?43±713? 97)kg/(hm~2 ? a) and (0.136±0? 192)kg/(hm~2 ? a) in 2013;The differences between the CO_2 emissions under different irrigation treatments were both significant (p< 0.05) in 2012 and 2013. If modifying all the existing furrow irrigation vineyards to drip irrigation vineyards in Ningxia,the Global Warming Potential (GWP)reduction amounts of CO_2 and CH_4 emissions could be estimated as about 70 771 400 kg CO_2 equivalent in 2012 and 44 025 800 kg CO_2 equivalent in 2013 respectively. Thus, drip irrigation system which can effectively inhibit the purge losses of CO_2 and CH_4 emission from soil is an irrigation method and has greater reduction potential for emissions of CO_2 and CH_4. |
