Abstract: To develop and promote the application of safe, non-toxic, efficient and environment-friendly bioorganic fertilizer, the active ingredients and function of seaweed fertilizer and the latest research progress on the application of various types of seaweed fertilizers in rice are summarized. (1) The seaweed fertilizer contains high concentration of active amino acid, polypeptide, natural plant hormone precursors and betaine compared with the chemical fertilizer. It has also become a hot product in fertilizer production because of the modulation of hormone and nutrient balance in the plants, enhancing immunity and healthy growth of crops, and improving the yield and quality and other advantages; (2) the seaweed foliar fertilizer, solid fertilizer, liquid fertilizer, seaweed biological organic fertilizer and other new types of seaweed products have been produced in recent years with the deepening research and development of seaweed; (3) due to the prominent effects and the increasing demand of seaweed fertilizer, the market of seaweed fertilizer is in a mess, and the qualities of seaweed fertilizer products are of uneven levels in the market in recent years; (4) the industry of the seaweed fertilizer will enter a new stage of standardized development markets in China based on the standard HG/T 5050-2016 Alginate Fertilizer, the national industrial standard HG/T 5049-2016 Urea Containing Alginate released officially on April 1st, 2017 and the implementation of the People''s Republic of China Agricultural Industry Standard NY 884-2012 of bio organic fertilizer.
