The core of tomato seed pellet treatment is to form uniform particles through layered encapsulation, taking into account both the seed's activity and the suitability for sowing. The specific steps are as follows:

1. Pre-treatment: Preparation of seeds and materials

Select healthy tomato seeds, remove damaged and shriveled ones to ensure the germination rate.

Prepare core materials: pellet powder. If necessary, some functional components  diluted according to instructions) can also be prepared.

Tools preparation: seed pellet machine, drying equipment

2. Key Steps: Layered Encapsulation into Granules

Base Layer: Pour the pre-treated seeds into a blender, start at a low speed and add water in small amounts multiple times to moisten the seeds without causing them to clump.

Coating: Apply the coating evenly, stir until a thin powder layer forms on the surface of the seeds. Repeat the "add water - apply coating" process to gradually increase the size of the particles.

Adding Functional Components: When the particle diameter reaches approximately 0.5mm, mix the diluted functional components into the binder and continue the encapsulation process to ensure that the active substances are evenly attached.

Completion: Once the particle diameter meets the requirements, release.

3. Post-processing: Drying and Inspectio

Drying: Place the seed pellets on a drying device and ensure the moisture content drops to 8%-10% (to prevent damage to the seed embryos due to high temperatures).

Inspection: Randomly select some of the seed pellets and conduct a germination test to ensure the germination rate is not lower than 90% of the original seeds.

Storage: Seal the dried seed pellets and store them in a cool and dry place to prevent moisture absorption or exposure to high temperatures.
