Example Embodiment
[0057] Example 1 Single layer seed coating
[0058] figure 1 The plant seeds with a single coating layer prepared by the electrostatic dry powder coating technology in Example 1, including the plant seeds 1 and the coating layer 2, are prepared as follows:
[0059] (a) Prepare plant seeds to be coated
[0060] The plant seeds to be coated need to be pre-treated before coating, such as: cleaning, eliminating stubborn grains, small grains, broken grains, seeds with diseases and insect pests and various sundries; use sunlight to promote the activity of enzymes in the seeds , Reduce the content of germ-inhibiting substances in the seeds, increase the germination rate and play the role of sterilization; use water or medicine to soak the seeds to promote seed germination and eliminate pathogens; to obtain clean plant seeds that meet the coating requirements.
[0061] (b) Place the seeds to be coated in the coating machine
[0062] Place plant seeds in a grounded coating machine and turn on t...
Example Embodiment
[0070] Example 2 Multi-layer seed coating
[0071] The preparation method of plant seeds with multiple drug coating layers is as follows:
[0072] (a) Prepare plant seeds to be coated
[0073] The plant seeds to be coated need to be pretreated before being coated, such as: cleaning, eliminating stubborn grains, small grains, broken grains, seeds with diseases and insect pests and various sundries; sun exposure can promote the enzymes in the seeds Activity, reduce the content of germ-inhibiting substances in the seeds, increase germination rate and sterilization; use water or medicine to soak the seeds to promote seed germination and eliminate pathogens; to obtain clean plant seeds that meet the coating requirements.
[0074] (b) Place the seeds to be coated in the coating machine
[0075] Place plant seeds in a grounded coating machine and turn on the coating machine. The heating function of the mechanical device is used to heat the seeds, and the seeds are heated to 20°C to about 80°...
