【目的】为了探索生态可持续的稻作模式,对比研究了长江中下游地区双季稻和再生稻稻作模式的产量潜力和CH_4排放特征,以此为选取绿色、生态经济可持续的稻作模式提供科学依据.【方法】于2017-2018年依托湖南省益阳市大通湖区宏硕生态农业农机合作社科研基地,设置了双季稻和再生稻2种模式,对比分析了产量潜力、稻田生育期间CH_4排放动态和稻田生态系统CH_4季节性累积排放规律以及评估了单位产量稻田CH_4排放.【结果】试验期间,从产量方面来看,双季稻早稻产量为7.37 t·hm~(-2),再生稻头季产量为8.84 t·hm~(-2),头季相比早稻增产19.95%.双季稻晚稻产量为6.82 t·hm~(-2),再生稻再生季产量为3.39 ...

【Objective】In order to explore the ecologically sustainable rice planting model, the yield potential and CH4 emission characteristics of traditional double-cropping rice and emerging ratoon rice in the middle and lower reaches of the Yangtze River were compared, so as to provide a scientific basis for selecting a green and ecologically sustainable rice farming model. 【Method】In 2017-2018, relying on the research base of Hongshuo Eco-Agricultural Machinery Company in Datonghu District, Yiyang City, Hunan Province, two models of double-croppi...
