摘　　要：水稻在种子萌发期和苗期较为脆弱,易受病虫害和低温等因素影响,如果秧苗期出现问题,会造成大面积减产。种衣剂的作用是保护作物安全度过秧苗期。有研究表明,在使用种衣剂后对裂颖种子和低温胁迫下的种子有修复作用,对秧苗素质有一定的促进作用。水稻对种衣剂的耐水性和通透性要求较高,其核心技术是成膜助剂的选择,目前成膜剂主要是合成高聚物类成膜剂。在我国,水稻种植面积占作物种植总面积的1/4,但国内登记515种种衣剂仅有55种水稻种衣剂,水稻种衣剂行业发展潜力巨大。Rice is vulnerable at seed germination stage and seedling stage and is susceptible to diseases and insect pests and low temperature.If rice is injured at the seedling stage,it will result in large-scale yield reduction.The main function of rice seed coating agent is to protect crops at the seedling stage.It was also found that the seed coating agent could repair the seeds of split glume and seeds under low temperature stress,It can promote seedling quality to a certain extent.There are higher water tolerance and more permeability requirements for rice seed coating agents.One of the core technology is the selection of film-forming agents,At present,the main film-forming agent is mainly synthetic polymer film-forming agent.In China,the rice cultivation area accounts for 1/4 of the total of the total crop cultivation area.However,there are only 55 rice seed coating agents registered in China,and the development potential of rice seed coating agents industry is huge.
