Abstract：Green seed pelleting is a powerful measure to realize the mechanized precision sowing in industrial seed culture.Green onion is one of the main season vegetables,but its seeds are small and irregular,which cannot meet the requirements of intensive production.In this study,the pelletization and germination parameters of seed pelleting of green onion with different fillers were measured and analyzed,and comprehensively evaluation using membership function method for partial indexes.The results showed that compared with attapulgite,bentonite was one of the ideal fillers for seed pelleting of green onion which shaped closed to circular,and germination indexes were significantly better than that of attapulgite.Perlite could promote germination of pelleted green onion seeds in pelleted fillers.The pelleted seeds prepared by mass ratio of perlite,bentonite,talcum powder were 4∶26∶70 conformed to the requirements for seed pelleting,and each germination parameter was superior to those prepared by bentonit∶talcum powder(30∶70).This study clarified the favourable effect of pelleted green onion seeds prepared by bentonite∶talcum powder(30∶70)and perlite∶bentonite∶talcum powder(4∶26∶70)with distilled water used as binder,providing reference for mechanized precision sowing of green onion seed pelleting in industrial seed culture.
