1. Material status: liquid 2. Color: green 3. How to use: The proportion of liquid water-soluble fertilizer is 5%-20%, and the proportion of solid water-soluble fertilizer spraying is 5-20%. Shandong Jiejing Group implements the Taishan Scholars Blue Industry Talent Team Project New Sanlian Green Chemical Process Innovation Industrialization Project based on the use of biological extraction technology to extract the seaweed active substance essence-seaweed polyphenols, except for seaweed polyphenols in the original seaweed extract concentration , Iron, manganese, copper, molybdenum, boron, magnesium and other trace elements and polysaccharides, salicylic acid, jasmonic acid and other natural substances. It can effectively stimulate the production of non-specific active factors in plants and regulate the balance of endogenous hormones, improve the transport effect of nutrients in crops, induce crop growth and reduce abiotic stress mechanisms, and stimulate crop defense and osmotic protection. Enhance the resistance of crops, improve the effect and utilization of pesticides, and perform well in improving the physiological characteristics of crops.
