摘要
该项研究针对井灌稻井水水温低的障碍因素改变了常规的栽培方法，把地耙平后，筑起５０～６０厘米宽的平顶垄状的沟台，在沟中灌水养鱼，在台上栽稻，使水稻处在湿润状态下生长。从而提高水温、地温，改善土壤理化性质，达到早熟、高产的沟台带状栽培新方法。经１９９１～１９９４年四年试验结果表明，比常规栽培提早５～７天返青，分蘖和出叶速度提早５天以上，增加了有效分条，提早６～８天成熟，增产７．８～２２．５％。
In rice production practices at home and abroad, rice transplanting was conductedafter harrowing. However because of the low temperature of underground water the technique described in this paper was great different from the conventional Cultivation methads.That is after harrowing, set up ditches and platform ridges with width 50～60cm respectively. In ditches, fingerlings was stocked and on the platform double rows of rice were transplanted. This method can increase water and soil temperature, ameliorate soil physical and chemical features. So it is a promoting maturity and increasing yield method. Four years(1991～1994 ) experimental results Showed that this method can make seedlings returninggreen 5～7 days earlier, tillering 5 days earlier and ripening 6～8 days earnner than conventional one and increase yield by 7. 8～22. 5 percent.
