PROBLEM TO BE SOLVED: To solve rice producers usual dilemma in which the rice producer wishes to suppress growth of rice plant for preventing it from falling down, whereas the rice producer also wishes to increase yield that is, in a case where the rice producer who wishes to increase yield so as to increase benefit tries to increase yield, a direct and effective approach is to increase the amount of fertilizer to be applied, while in a conventional agricultural method, in a case where the amount of fertilizer is increased to an amount over the acceptable amount, the rice plant excessively grows and becomes easily falling down, resulting in requirement of a harder burden upon harvesting and reduction in yield due to the fallen down rice plant.SOLUTION: There is provided a method comprising the following features. In cultivation of rice plant, water to be supplied to cultivated field as cultivated field water is subjected to electrolysis, and then being separated by a separator. All or main part of water to be supplied to the cultivated field is consisting of water comprising anion without comprising cation as much as possible. The water subjected to the process is supplied as the cultivated field water just after planting in rice cultivation and, thereafter, when water supply is required in cultivated field.COPYRIGHT: (C)2014,JPO&INPIT【課題】 収量を増やし利益を増加したい米生産者が、収量を増加させようとする場合、直裁的かつ効果的な行為は施肥量を増やすことである。しかし従来農法において施肥量を許容以上に増やした場合、イネは成長過多となり、倒伏しやすくなる。倒伏したイネは、収穫の際、多くの労力を必要とするばかりか収量も低下せざるを得ない。この様に米生産者は、倒伏防止のために成長を抑制したい一方で、収量を増大させたいとするジレンマを常に抱えている。【解決手段】 イネの栽培において、圃場水として圃場に与える水を電気分解した後、分離器によって分離する事で、陽イオンを含んだ水を圃場に出来るだけ入れることなく、陰イオンを含んだ水の全部、または主要な一部とし、稲作での田植え直後、及び、それ以降、圃場で給水が必要となる際、上記の処理を施した水を圃場水として与える事を特徴とする方法を提供する。【選択図】なし
