The standards for seed granulation mainly include the following aspects:

1. Appearance: Seed pellets should have a uniform shape and size, without obvious breakage, deformation, or clumping. The surface should be smooth and free from obvious cracks or spots.

2. Diameter: The diameter of seed pellets should meet the specified range. The specific diameter standards will vary depending on different crops and varieties.

3. Weight: The weight of seed pellets should meet the specified range. Generally speaking, the weight of seed pellets should be within a certain standard range to ensure that the amount of each seed is relatively uniform.

4. Density: The density of seed pellets should meet the specified range. Excessive or insufficient density can affect seed germination and growth.

5. Ingredients: Seed pellets should meet the specified ingredient requirements. This includes indicators such as seed purity, impurity content, vitality, and germination rate. The seeds in the seed pellets should be of high quality and purity, and have good germination ability.

The main indicators for seed quality inspection include the following aspects:

1. Purity: Seed purity refers to the proportion of impurities of the same or different species contained in the seed. Seeds should have high purity, that is, the impurity content should be as low as possible.

2. Humidity: Seed humidity refers to the moisture content contained in the seed. The humidity of seeds should be within an appropriate range. Excessive or insufficient humidity can affect the germination and preservation performance of seeds.

3. Vitality: Seed vitality refers to the growth and reproductive capacity of seeds. Seeds should have good vitality to ensure their normal germination and growth.

4. Germination rate: Seed germination rate refers to the percentage of seeds that germinate under certain conditions. The germination rate of seeds should reach a certain standard to ensure the planting effect of seeds.

5. Impurity content: The impurity content in seeds should be controlled within a certain range to ensure the quality and purity of the seeds.

In summary, the standards for seed pelletization mainly include appearance, diameter, weight, density, and composition. The main indicators for seed quality inspection include purity, humidity, vitality, germination rate, and impurity content. The reasonable control and testing of these standards and indicators can ensure the quality and planting effect of seeds.
