【摘要】 研究了苏南稻田不同种植制度与土壤持续生产力的关系。维持土壤持续生产力的实质是维持土壤肥力，多熟种植制度养分产出增加，加大了土壤养分的消耗，但有机物质生产增加，有利于有机物质归还和土壤有机质平衡。在多熟种植制度中间套插种绿肥等豆科养地作物和油菜、蔬菜等培肥作物，结合秸秆还田和轮作，将能维持稻田多熟制的土壤持续生产力。更多还原

【Abstract】 The results of studies on relationship between paddy soil sustainable productivity and cropping patterns in Southern Jiangsu showed that intercropping or relaycropping of green manure crops and rape or vegetables with grain crops combined with reasonable rotation cropping and straw returning could be helpful to the maintenance of soil fertility and the sustainable productivity of multiple cropping system.更多还原
