摘　　要：为在菜稻轮作田推广水稻免耕栽培和稀植技术提供技术参考,开展水稻免耕创新试验示范。在蔬菜收获后,直接在原蔬菜垄上移植水稻,应用免耕、垄作、旱育抛秧等技术。2006、2007年,中浙优1号、新两优6号两个优质稻品种平均产量分别为10.6 t/hm2、9.8 t/hm2,分别比常规抛秧田9.0 t/hm2、8.3 t/hm2,增1.6 t/hm2、1.5 t/hm2,增长显著。In order to promote technical reference to extension of rice no-tillage and low seeding density cultivation technology in vegetable-rice-rotation fields, a rice no-tillage demo and experiment was conducted. After the vegetable harvest, the rice seedlings were transplanted directly on the ridges integrated with no-tillage, ridge-planting and dry-fostering-seedling-broadcasting technologies. In 2006 and 2007, the yields of two rice varieties were 10.6t and 9.8t/hm2 respectively, 1.6t and 1.5t higher than the normal seedling-broadcasting cultivation.
