Embodiment 1

[0057] Embodiment 1 single-layer seed coating

[0058] figure 1 For the plant seeds with a single coating layer prepared by using electrostatic dry powder coating technology in this example 1, including plant seeds 1 and coating layer 2, the preparation method is as follows:

[0059] (a) Prepare the plant seeds to be coated

[0060] The plant seeds to be coated need to be pretreated before coating, such as: cleaning, eliminating grains, small grains, broken grains, seeds with diseases and insect pests and various sundries; use sun exposure to promote the activity of enzymes inside the seeds , Reduce the content of germination-inhibiting substances in the seeds, increase the germination rate and play a role in sterilization; use water or drugs to soak the seeds, thereby promoting seed germination and eliminating pathogens, etc.; to obtain clean plant seeds that meet the coating requirements.

[0061] (b) Place the seeds to be coated in the coating machine

[0062] Place the ...

Embodiment 2

[0070] Embodiment 2 multi-layer seed coating

[0071] Its preparation method of the plant seed with multi-layer medicine coating layer is as follows:

[0072] (a) Prepare the plant seeds to be coated

[0073] The plant seeds to be coated need to be pretreated before coating, such as: cleaning, eliminating grains, small grains, broken grains, seeds with diseases and insect pests and various sundries; using sunlight exposure can promote the enzymes in the seeds. Activity, reducing the content of germination-inhibiting substances in seeds, increasing germination rate and sterilizing effects; soaking seeds with water or drugs to promote seed germination and eliminate pathogens, etc.; to obtain clean plant seeds that meet the coating requirements.

[0074] (b) Place the seeds to be coated in the coating machine

[0075] Place the plant seeds in the grounded coating machine and turn on the coating machine. Using the heating function of the mechanical device to heat the seeds, the...

Abstract

The invention discloses a plant seed dry powder coating method, which relates to the technical field of seed treatment. The method includes the following steps: S100. placing seeds to be coated in a coating machine, heating the seeds to be coated, and simultaneously starting a mixing function of the coating machine to move the seeds to be coated; S200. spraying an atomized plasticizer solution onthe surfaces of the seeds to be coated; S300. uniformly spraying a powdery seed coating agent on the surfaces of the seeds to be coated by using electrostatic spraying equipment; and S400. continuously heating the seeds to be coated to solidify a film-forming polymer material in the seed coating agent and form a uniform coating layer on the surfaces of the seeds to be coated.

Description

technical field [0001] The invention relates to the technical field of plant seed treatment, in particular to a plant seed coating method. Background technique [0002] Seed coating technology uses the coating material composed of pesticides, fertilizers, insecticides, fungicides, adhesives, film-forming polymer materials, etc. A technology in which a coating agent is coated on the surface of seeds. The film-forming polymer material in the seed coating agent can form a film with capillary, expansion or fissure-type pores on the surface of the seed, and network the active ingredients and other inactive ingredients together, thus forming a microscopic film around the seed. "Active Substance Library". [0003] After the coated seeds are sown, the seed coating film absorbs water and swells in the soil, forming a protective barrier around the seeds to prevent diseases and insect pests, so as to sterilize the seeds and prevent the invasion of soil-borne pathogens. When the seed...
