METHOD OF REDUCING FALLING DOWN IN CULTIVATION OF RICE PLANT AND INCREASING YIELD

摘要

PROBLEM TO BE SOLVED: To solve rice producer's 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.
