摘要: 采用田间小区试验,建立了环渤海潮土区不同产田夏玉米氮、磷、钾肥的肥料效应模型,分析了玉米农田生态系统中,温室气体的直接和间接排放规律以及净温室气体排放平衡。结果表明,高、中、低产田经济最佳施肥量与最高产量施肥量相比,温室气体排放强度小,增温潜势大,且为温室气体的“汇”,可作为该地区夏玉米生产的科学施肥水平。

关键词: 环渤海潮土区, 夏玉米, 温室气体, 温室效应评价

Abstract: The field plot experiment was carried out to establish fertilizer effect models of nitrogen,phosphorus and potassium fertilizer in different yielding fields in the tidal area around Bohai sea.The direct and indirect emission laws of greenhouse gases andthe net greenhouse gas emission balance were analyzed in the corn farmland ecosystem.The results show that the greenhouse gas emission intensity of the optimal economic fertilization amount of high,medium and low yield fields is smaller than the highest yield fertilization amount,the potential for warming is large,and it is a “sink”of greenhouse gases,which can be used as a scientific fertilization level for summer maize production in this area.

Key words: tidal area around Bohai sea, summer maize, greenhouse gases, greenhouse effect evaluation
