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%。
This research aimed at changing the conventional cultivation method according to the obstacle factors of low water temperature in well-well rice water wells. After leveling the ground, a flat-ridge ridge ditch with a width of 50 ~ 60 cm was built, Planting rice on the stage, the rice in the wet state growth. Thereby increasing the water temperature, ground temperature, improve the physical and chemical properties of soil, to achieve precocious, high-yielding gully banding cultivation of new methods. The results of four years from 1991 to 1994 showed that the regrowth was accelerated 5 to 7 days earlier than that of conventional cultivation, the tillering and leaf-out rate were earlier than 5 days, the effective sub-section was increased, and the maturity was 6 to 8 days earlier and the yield was 7.8 to 22 .5%.
