悦丰牌营养源(以下简称悦丰)是中科院上海有机化学研究所等单位研制,由福建省莆田糖厂经济开发公司开发的国家级成果。人所共知“生命是蛋白体的存在方式”,而蛋白体是蛋白质和核酸的复合体,而核酸的单体即是核苷酸。研究表明:核苷酸对作物的主要作用是嘧啶类碱基和嘌呤类碱基。它们能促进作物根系发育,丰富叶绿粒含量,因而适期施用能促进作物早熟,优质,高产。悦丰牌即是以核苷酸制剂为主的营养型系列产品,1987年江苏省标准局将其列为生产无公害蔬菜的专用营养液之 Yuefeng brand nutrition source (hereinafter referred to Yuefeng) is the Chinese Academy of Sciences Shanghai Institute of Organic Chemistry and other units developed by Putian, Fujian Province Economic Development Corporation Sugar developed national results. It is well known that “life is the existence of the body of a protein,” which is a complex of proteins and nucleic acids, and the monomer of a nucleic acid is a nucleotide. Studies have shown that: the main role of nucleotide on crops are pyrimidine base and purine base. They can promote the root development of crops and enrich the content of leaf green grains. Therefore, they can promote the early maturity, high quality and high yield of crops. Yuefeng brand that is based on nucleotide preparations of nutrition-based products, in 1987, Jiangsu Province, the Bureau of Standards will be classified as its production of pollution-free vegetables dedicated nutrient solution
