Seed pelleting is a new type of seed treatment and processing technology.The research and development of seed pelleting play a role in promoting the development of the seed industry.The main production process is as follows.The seeds are rotated,suspended,and tumbled under the driving force from mechanical and steam rotation in the pellet machine.Then,atomized liquid is added to moisten the surface of the seeds,and then powder and adhesive are added to form pelletized seeds.The application and promotion of pelletized seeds have the advantages of improving seed germination rate,enhancing resistance to diseases and pests,and realizing precision mechanical sowing.Overseas,the pelleting technology for tiny seeds such as crops,vegetables,and flowers has become mature.Seed pelleting technology in China for crops such as sugar beet,cotton,corn,sorghum,and rice is gradually becoming mature,but it is still behind overseas mature technology.In the future,it is necessary to pay attention to the screening of pelletized fillers and chemicals,their impact on the environment,and the uniformity of pelletized seeds.It is also important to improve the growth and development of seeds and their resistance to pests and diseases,strengthen quality testing,and reduce material costs.
