Celery seeds are pelleted (the wrapping of small seeds into larger, more regular particles) for several reasons, especially in crops with small seeds such as celery:
1. Improve seeding accuracy and efficiency
Small seeds: celery seeds are very small (1000-grain weight is only about 0.5 grams), and it is easy to adhere or distribute unevenly when sowing directly, resulting in different seedling densities.
Mechanized seeding needs: after pelleting, the seed volume increases and the weight increases, which is more suitable for the precise operation of precision seeder (such as air suction seeder), reducing missing seeding or replay, and saving seed costs.
2. Adapt to special planting needs
Seedling tray sowing: celery often need seedling transplanting, pelleted seeds in the hole tray single seeding success rate is higher, reduce the cost of replacement.
Hybrid seed efficiency: celery hybrid seed price is higher, pelletizing can reduce waste, improve utilization.
3. Improve germination and seedling formation rate
The role of wrapping materials: Pelleting usually contains clay, fertilizer (such as starter fertilizer), water retaining agent, etc., which can provide water and nutrition for the initial germination of seeds, especially in dry or poor soil.
