Introduction to Seed Pellet Granulation

Seed pelletization is a new type of seed processing technology, which is a type of "seed coating" technology. Through pelletization machinery, seeds with light weight, irregular surface, or extremely small seed pellets are formed into a certain strength, shape, and weight, thereby achieving the effects of "small seed large pelletization", "light seed heavy pelletization", and "irregular seed regularization". This is conducive to large-scale and industrial production of mechanized seeding, and improves the resistance of seeds to adverse environments.

1、 Types and advantages of seed pellet granulation

1. Heavy granulation (increasing volume by 3-20 times)

Advantages: It can withstand wind, drought, improve survival rate, and is convenient for mechanized sowing

2. Flat granulation (small seeds)

Advantages: Medicinal herbs, grass, and trees are predominant, and seeds become larger and heavier, improving the accuracy of aerial seeding and facilitating the stability of mechanized seeding, ensuring seeding quality.

3. Rapid cracking of pellets (self disintegration in a short period of time)

Advantages: It is beneficial for seeds to release nutrients and facilitate germination.

2、 Applicable seeds

Vegetables: Carrots, scallions, onions, chili peppers, tomatoes, asparagus, lettuce, chicory, celery, lettuce, oats, etc

Medicinal herbs: Atractylodes macrocephala, Atractylodes macrocephala, Platycodon grandiflorus, Bupleurum chinense, Astragalus membranaceus, Scutellaria baicalensis, Angelica dahurica, Fangfeng, Perilla frutescens, Achyranthes bidentata, Burdock, etc

Other categories: seeds of rice, forage, flowers, etc

3、 Quality standards for pelletized seeds

1. Pellet granulation is approximately circular or spherical, with uniform size and smooth surface

2. Single compressive strength ≥ 160g

3. Single seed rate greater than or equal to 99%

4. Seed moisture content ≤ 8%

5. Seed rate ≥ 99%

6. No self-discipline ≤ 0-1%

4、 The benefits of pelletizing seeds

1. Provides a microenvironment for seed germination

2. Improved seed resistance

3. Beneficial for mechanized precision sowing and reducing the labor required for seedlings during the seedling stage

4. Beneficial for improving stress resistance and enhancing seedling quality
