摘要
双季稻是湘潭地区稻田传统种植模式。为探索该地区稻田适宜粮食作物替代种植模式,在湘潭县易俗河镇比较了3种粮食作物种植制度(双季稻、早稻—秋玉米、春玉米—晚稻)的生产效益。结果表明:双季稻模式纯收入最高(16 347.7元/hm^2),其次是早稻—秋玉米(15 332.1元/hm^2),春玉米—晚稻模式总效益最低(14 260.8元/hm^2)。与双季稻模式相比,早稻—秋玉米模式经济效益下降不显著(降幅6.2%),人工投入少,且有水旱轮作的潜在优势,初步认为湘潭地区以早稻—秋玉米替代双季稻是可行的。
Double cropping rice is the traditional planting mode in paddy field in Xiangtan area.In order to explore the op-timal grain crop substitute planting mode in paddy field in this area,the production benefit of three grain cropping systems, double cropping rice,early rice -autumn maize,spring maize -late rice in Yisuhe town,Xiangtan county,were compared. The results showed that：the net income of double cropping rice mode was the highest （￥16 347.7 yuan/hm2 ）,the next was early rice -autumn maize mode （￥15 332.1 yuan/hm2 ）,and that of spring maize -late rice mode was lowest （￥14 260.8 yuan/hm2 ）.Compared to double cropping rice mode,the economic benefit of early rice -autumn maize mode de-creased inconspicuously,while it need less labor input and has potential advantage in paddy -upland rotation.So the sub-stituting double cropping rice with early rice -autumn maize is feasible.
