江苏沿江经济区多元多熟种植方式及效益评价

Evaluations on Multicomponent-Multiple Cropping Patterns and Their Comprehensive Benefits of Along Changjiang River Economic Zone in Jiangsu

在江苏沿江经济区设置了２３种多元多熟种植方式进行定位对比试验，从增粮、增收和省工３个方面进行了综合评价。结果表明，稻田以“春玉米－水稻”为基础，旱地以春玉米为中心的粮饲经菜４元结构的省工型种植方式是本区集约高效持续种植制度的发展方向。

The comprehensive benefits of 23 multicomponent-multiple cropping patterns of Along Changjiang River Economic Zone in Jiangsu are evaluated in three aspects:cereal yield increasing,return increasing and labor saving.The results indicate that for the development of intensive.high-efficient and sustainable cropping systems in this Zone,the labor saving multiple cropping patterns consisting of cereal crop,feed crop,cash crop and vegetable crop are suggested.The paddy field and the upland in those cropping patterns are based on spring corn-rice and centred on spring corn respectively.
