沈阳地区冬小麦和水稻复种的可行性试验简报

在沈阳地区，采用在冬麦北移育种中形成的冬麦品种9625作为复种前茬，以及成熟期较短的水稻品系87913和黑糯1号作为下茬进行麦稻复种可行性研究。结果表明，在沈阳地区麦稻复种是可行的。分析认为麦后复种水稻的产量比一季单作小麦的产量高，同时提高了经济效益，增加了耕地和光能利用率，提高了土地生产力。并提出上下茬搭配的作物栽培管理的各项措施。同时分析了在沈阳地区发展麦稻复种的限制性因素。

The Feasibility Analysis of Multiple Cropping of Winter Wheat and Rice in Shenyang Area

The multiple cropping pattern that Winter wheat variety 9625 was as preceding crop and two types of rice varieties as succeeding crops was studied comparatively. The results indicated the multiple cropping of wheat and rice was feasible in Shenyang area. The yields of multiple cropping were higher than those of single cropping wheat. And the multiple cropping patterns advanced economic beneficial and made use of the light energy and land resources fully. The methods of cultivating management of forward and below stubble crops were put forward. And the limited factors of developing multiple cropping of wheat and rice were pointed out in Shenyang area.
