摘　　要：在潜育化稻田土壤上进行了双季稻免耕抛秧稻草还田种植模式和当地习惯翻耕种植模式的对比试验示范,从水稻产量、成本投入和经济效益上比较分析了两种种植模式的应用效果。结果表明,与当地习惯种植模式相比,双季稻免耕抛秧稻草还田种植模式提高了水稻产量,增加了稻谷产值,降低了化肥投入成本,减少了翻耕成本,提高了种植双季水稻的经济效益。The rice yield, input costs and economic benefits of no-tillage, cast-transplanted and rice-straw incorporation cropping pattern and local conventional tillage cropping pattern were analyzed in gleyed double-rice paddy soil. Planting techniques and utilization effects were compared in two cropping patterns. Compared with the local conventional tillage cropping pattern, no-tillage, cast-transplanted and rice-straw incorporation cropping pattern could increase the yield and output value of rice grain, reduce fertilizer input costs and tillage costs, and improve economic benefits of double-rice cropping.
