水稻对硅的吸收量大，并可提高水稻抗逆性，利于水稻高产稳产。在上海市农技服务中心和宝钢集团开发总公司的支持下，进行本试验。１基本情况和设计１．１基本情况试验用三种硅肥（宝钢集团开发总公司），分别以Ｓ１、Ｓ２、Ｓ３表示，Ｓ１为单质硅，Ｓ２和Ｓ３为复混硅，混有
Rice absorption of silicon large, and can improve rice resistance, conducive to high and stable yield of rice. This experiment was carried out with the support of Shanghai Agricultural Technology Service Center and Baosteel Group Development Corporation. 1 Basic situation and design 1.1 Basic situation The experiment uses three kinds of silicon fertilizer (Baosteel Group Development Corporation), respectively S1, S2, S3, said S1 is silicon, S2 and S3 are complex silicon, mixed with
