摘要
通过比较同一水稻品种在两种灌溉用水、两种灌溉时间、四种灌溉方式的栽培措施下对产量的影响,研究不同灌溉制度下水稻产量的变化规律。试验结果表明:生产上应该提倡的灌溉方式是浅、晒、深、湿;利用地表水灌溉比利用地下水灌溉更容易获得较高的产量。
The law of rice yield under the different irrigation modes was studied by comparing the effect of two irrigation temperatures, two irrigation periods and four irrigation modes on yield of the same rice variety. The results showed： The most recommendable irrigation mode in practice was shallow, drying, deep and wet;the utilization of surface water irrigation was much easier to acquire high yield.
