摘要: 连续十年的定位试验结果表明,周年淹水能明显提高稻田的有机质含量和氮素营养水平。在相同施肥水平,冬水田水稻单产10年平均两季田增产15.6%——20.0%。这表明冬水田确实具有自营培肥省肥高产的功能。这一研究结果,对客观评价四川盆地丘陵区冬水田存在价值及其合理利用,在生产上和学术上均具有重要意义。

Abstract: The results of long term(10 years) experment show that it is very obvious to increase the content of organic matter and nitrogen in waterlogged field during ten years. As the same of fertilizer. the average yield of rice in waterloggod field is more than 15.6-20.00% in paddyupland rotation field, which shows the waterlogged field has a function to save fertilizer and cultivate fertilizer by itself. If is significance in agricultural production and sciences to keep certain region rationally utilizing the waterlogged field in purple hill area in the Sichuan Basin.

Key words: WATERLOGGED FIELD, SOIL FERTILITY, YIELD
