科学试验促进了水稻高产,搞好水稻生产必须依靠科学试验。吉林省东辽县金满水库灌区,为了充分提高灌溉效益,促进水稻高产,从1973年以来,坚持在水稻田里搞科学试验。先后开展了灌溉制度、水稻需水量、水稻旱种、喷灌、品种对比、磁化水种水稻等项科学试验。坚持“试验、示范、推广” Scientific experiments to promote high-yielding rice, rice production must rely on scientific experiments. Jinman Reservoir in Dongliao County, Jilin Province, has been conducting scientific experiments in paddy fields since 1973 in order to improve irrigation efficiency and promote high-yielding rice. Has carried out irrigation systems, water demand, dry cultivation of rice, sprinkler irrigation, species comparison, magnetized water rice and other scientific experiments.
