玉米秸秆还田和施氮方式对麦田N 2O排放的影响
Effects of Corn Straw Returning and Nitrogen Fertilizer Application Methods on N2O Emission from Wheat Growing Season
摘要
Abstract
Based on a wheat field experiment, the effect of four treatments such as no-straw returning(SN), straw returning(SR), control release fertilizer application(SRC)and nitrogen drilling(SRR)on N2O emission was studied using the static chamber method and the gas chromatographic technique. The results indicated that the wheat field was the sources of N2O emission. The N2O emission peaks followed each time of fertilizer application and irrigation, and usually continued for 1~2 weeks. N2O emissions accounted for more than 40%of total emis-sions during the N2O emission peak. The amount of N2O emission during three growing stage of wheat from high to low was arranged in turn pre-wintering period, post-wintering period and wintering period. N2O emission could be increased by straw returning. Compared with SN, N2O emission could be enhanced by 48.6%under SR. Both SRC and SRR could decrease the N2O emission, increase wheat yield and eco-nomic benefit, especially the latter. Nitrogen drilling is a good method for yield increment and N2O abatement.关键词
