Disclosed is a coated rice seed having a coating layer on the surface of a rice seed, wherein: the coating layer includes an iron oxide, and at least one type of copolymer selected from the group consisting of styrene-butadiene copolymers and methyl methacrylate-butadiene-styrene copolymers and the content of said iron oxide is 30-90 wt% to 100 wt% of said coated rice seeds. Thus, it is possible to provide coated seeds that are less susceptible to bird damage, and that do not have the problem of reduced germination rate as in conventional iron coatings.本發明係藉由於水稻種子的表面具有塗覆層而成之經塗覆之水稻種子,前述塗覆層係含有氧化鐵、與選自由苯乙烯丁二烯共聚物及甲基丙烯酸甲酯丁二烯苯乙烯共聚物所構成之群組中之至少1種的共聚物,相對於前述經塗覆之水稻種子100重量%,前述氧化鐵的含量為30~90重量%之經塗覆之水稻種子,可提供一種不易受到鳥害,且無在以往鐵塗覆中之發芽率低落的問題之塗覆種子。a‧‧‧箭頭b‧‧‧水稻種子
