一、试验目的叶面施肥,可使营养物质从叶部直接进入体内,参与作物的新陈代谢与有机物的合成过程,比土壤施肥更为迅速有效,因此,推广叶面施肥具有十分重要的意义。喷施宝有机水溶肥料是一种复合型叶面肥,由农作物生长所必需的氮、磷、钾、硼、锌、锰等十几种矿质营养元素和腐殖酸、柠檬酸、氨基酸、维生素、多糖等多种植物源有机营养调理成分经科学螯合工艺浓缩而成,具有“营养、调节、抗逆”等作用,据研究表 First, the purpose of the experiment Foliar fertilization, nutrients can be directly from the leaves into the body, involved in crop metabolism and organic synthesis process, more quickly and effectively than soil fertilization, therefore, the promotion of foliar fertilization is of great significance. Penshibao organic water-soluble fertilizer is a compound type of foliar fertilizer, required by the crop growth of nitrogen, phosphorus, potassium, boron, zinc, manganese and a dozen mineral nutrients and humic acid, citric acid, amino acids, vitamins , Polysaccharides and other plant sources of organic nutrition conditioning ingredients concentrated by the scientific chelation process, with “nutrition, regulation, resistance” and so on, according to the study
