Technical Field

The invention belongs to the field of agricultural planting, and particularly relates to a seed coating agent for rice in northeast cold regions.

Background

The process of coating seeds in a dry or wet state with a composition such as a pesticide or fertilizer containing a binder to form a protective layer having a certain function and coating strength on the outside of the seeds is called seed coating, and the composition coated on the outside of the seeds is called a seed coating agent or a coating agent. The seed coating agent is developed on the basis of seed dressing agent and seed soaking agent, and has the greatest advantage that a firmer film can be formed outside seeds, so that the seed coating agent is named.

By adopting seed soaking or medicament seed dressing, the medicament on the surface of the seed can be dissolved when meeting water after being sown into the soil, the pesticide effect is quickly reduced or disappears, and the pesticide effect time is short. The seed coating agent is coated on the seeds to form a solidified film immediately, the seeds swell when encountering water after entering the soil and can not be dissolved, and along with the germination, emergence and growth of the seeds, the effective components on the seed coating can be gradually released and absorbed by root systems to conduct all parts of plants, so that the effective period of the agent is prolonged.

The seed coating agent generally consists of two parts, one is an active ingredient which is an effective ingredient directly playing a role in the seed coating agent, and the type, the composition and the content of the active ingredient directly influence the efficacy of the seed coating agent. The second is film forming agent and corresponding auxiliary agent, which is important component for maintaining the physical and chemical properties of the seed coating agent and controlling the slow release of the active component in the coating. The film forming agent mainly has the function of adhering the effective components on the surface of the seed and forming a uniform and smooth medicine film. At present, the seed coating agent has poor insect pest prevention effect and poor cold resistance, and the emergence rate is low.
