为探求水稻的高产省水灌溉方法,我们试验站从1980年开始进行了灌溉制度的试验研究。经过不断总结提高,“前深、中薄,后间歇”的灌溉技术,获得了增产省水效果。1984年又用18个小区,分别按“前深、中薄、后间歇”、“浅灌勤灌”和“浅、后干湿”三种灌溉方法,各自进行6次循环试验。按第一种方法灌溉的早稻平均亩产984.3斤,比按第二种方法增产206斤,比按第三种方法增产113.2斤。
In order to explore high-yielding and water-saving irrigation methods for rice, our experimental station started the experimental study on irrigation system from 1980. After continuous improvement and improvement, “before the deep, thin, intermittent intermittent” irrigation technology, access to the effect of increasing production of water. In 1984, another 18 plots were used to carry out six cycles of tests according to the three irrigation methods of “deep before, after thin, after intermittent”, “shallow irrigation and shallow irrigation” and “shallow and backward wet and dry” respectively. According to the first method, the average yield of early rice irrigated was 984.3 kg, 206 kg more than that of the second method and 113.2 kg more than that of the third method.
