Coated seeds are an important part of seed quality standardization. Seed coating technology is to apply seed coating agents containing pesticides, trace fertilizers, and plant growth hormones to the surface of the seed evenly through mechanical processing. It is a new technology developed in traditional soaking and seed dressing techniques. The coated seeds are all selected and processed, and their net quality and germination rate are high, which is conducive to the implementation of precision and semi-precision seeding. The coated seeds contain insecticides, fungicides, trace elements, and plant growth regulators, which can comprehensively prevent and treat seedling pests and diseases and supplement nutrients, and can promote seed germination, stimulate crop growth, and achieve the goal of seedling seedlings and seedlings. In the storage and use of coated seeds must pay attention to the following aspects: coated seeds are highly toxic, can not eat or do industrial and non-staple food processing raw materials. Coated seeds should be stored in a dry, cool and ventilated place. Keep out of the reach of children and livestock or poultry. Do not eat, smoke, or rub your face with your hands when sowing. Wash hands and face with soap and water immediately after sowing. Packing bags of coated seeds should be made of polypropylene woven bags. It is best not to use sacks to avoid inhalation of the sack fibers causing poisoning. The packaging bag should be burned or buried after use to prevent accidental loading of food and food. The utensils containing coated seeds must be thoroughly washed before use. The water for washing these utensils must not be poured into rivers or ponds, but can be poured into fields or roots. The coated seeds should not be soaked and germinated. Because the seed coating agent dissolves in water, it not only fails, but also inhibits the germination of the seed. Seed coating agent will break down in case of alkali, so it is not appropriate to use coated seeds in fields where the soil pH is greater than 8. Coated seeds are prone to rancid rot in high-humidity conditions, so they should not be used in low-lying areas or in depressions. The coated seed bogey is used together with herbicides such as dioscorea and can be used for 30 days after sowing. If you first use the enemy, then you need to sow 3 days later, otherwise it is prone to phytotoxicity or reduce the use of seed coating agents. Seed dressings containing carbofuran cannot be used on fruits and vegetables, and should not be used on leafy vegetables.
