变更施肥管理对不同肥力水稻土 CH4排放影响
Effects of Altered Fertilization on CH4 Flux from Paddy Soils with Different Fertilities
摘要
Abstract
Under the premise of keeping original test going on, and based on a 30-year fertilizer experi-ment in paddy soil, this test was conducted through altering some treatments.Four treatments were obtained as the original normal organic material treatment (NOM), the original chemical fertilizer treatment (CF), the treatment with normal organic material altered to chemical fertilizer ( N-C) and the treatment with chemical fertilizer altered to normal organic material ( C-N) .The CH4 flux of paddy soil under the four treatments was measured to study the effects of following-up fertilization management on it.The results showed that organic fertilizer could significantly increase the CH4 flux, while chemical fertilizer had little effect on it.CH4 flux also had a positive relationship with the increase of organic carbon in soil.The annual dynamics of CH4 flux had significant correlation with temperature, but had no simple correlation with water depth.关键词
