Description

Technical Field

[0001] The invention relates to the technical field of seed coating agents, and in particular to a multifunctional composite seed coating agent for promoting seed growth, and a preparation method and application thereof. Background Art

[0002] Seed coating agents are available in liquid and solid powder form. Some are prefabricated for long-term storage, while others are made and used immediately. They are developed based on suspensions, powders, and wettable powders. The active ingredients are required to be gradually released without any toxic effects on the germination and growth of crops. The seed coating film is water-permeable and air-permeable, and does not affect the life and respiration of seeds. Seed coating agents are highly efficient, economical, safe, long-lasting, and multifunctional.

[0003] Seed coating agent is a factory-produced brick-red powdery substance containing different pesticide ingredients and having a moldable appearance. Using this agent to coat seeds can prevent the invasion of pests and diseases in the soil after sowing. At the same time, as the seeds germinate and emerge from the soil, the agent is gradually released from the seed coating and absorbed by the crops, which can also prevent and control aboveground pests and diseases.

[0004] In modern agriculture, improving seed germination rate and growth quality is the key to ensuring crop yield. Traditional seed treatment methods often fail to achieve ideal results in complex and changing natural environments. Therefore, it is particularly important to develop a new seed coating agent that combines nutrient supply, growth promotion, and disease prevention.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0019] Preferably, the amount of water is 12.5 to 17.5 times the mass of the film-forming agent.

[0020] The third aspect of the present invention provides a use of the multifunctional composite seed coating agent for promoting seed growth or the multifunctional composite seed coating agent for promoting seed growth prepared by the above preparation method in seed coating.
