Comparison of the Grain Production Benefit among Different Cropping Systems in Paddy FieId in Xiangtan Area
摘要
Abstract
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.关键词
