Seed coating technology is a plant protection technology widely promoted in my country in the 1990s. It has the characteristics of comprehensive control, low toxicity and high efficiency, saving seeds and drugs, protecting the environment, and high input-output ratio. Seed coating is to use mechanical or manual methods to evenly coat the seed coating agent containing insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents in a certain proportion. Cover the surface of the seeds to form a smooth, firm film. Along with the surface of the seeds, a smooth, firm medicinal film is formed. With the germination, germination, emergence and growth of the seeds, the active ingredients in the coating are gradually absorbed by the roots of the plants and transmitted to all parts of the seedlings, so that the seeds and seedlings can prevent and control the seed and soil bacteria and underground and above-ground pests . The micro-fertilizer in the drug film can fully exert its effectiveness before the base fertilizer takes advantage of it. Therefore, the coated seeds grow vigorously at the seedling stage, the leaves are dark green, the root system is developed, and the plants are strong, so as to achieve the purpose of increasing production and income.
