PROBLEM TO BE SOLVED: To provide a rice growing method which makes it possible to grow rice without flooding management, can be conducted at low cost, and can also reduce the cadmium content of rice without inhibiting rice growth.SOLUTION: This invention provides a rice growing method in which a cadmium absorption inhibitor of an iron precipitate composed of an iron hydroxide is applied to a field and rice is grown. In preferable embodiments, the iron hydroxide (Fe(OH)3) content of the cadmium absorption inhibitor is 25 mass% or more, and the cadmium absorption inhibitor is applied to a field at the rate of 25 kg/50 m2 or more.COPYRIGHT: (C)2014,JPO&INPIT【課題】湛水管理を行うことなく稲を栽培でき、安価であり、かつ稲の生長を阻害することなく米中のカドミウム含有量を低減することができる稲の生長方法の提供。【解決手段】鉄水酸化物からなる鉄殿物のカドミウム吸収抑制剤を田圃に散布し、稲を栽培する稲の生長方法である。前記カドミウム吸収抑制剤における水酸化鉄(Fe(OH)3)の含有量が25質量%以上であり、前記カドミウム吸収抑制剤を25kg/50m2以上となるように田圃に散布する態様、などが好ましい。【選択図】なし
