Abstract:: Field plot experiment were used to study the regulation of dry matter accumulation，the characteristics of selenium’s distribution，absorption，and accumulation in garlic.The results showed that dry matter accumulation quantity of garlic was increased with the increasing of the plant growth from seedling stage to flower bud differentiation period，the peak was 15 022.50 kg/hm²，and then in equilibrium；the size of selenium content at different periods was flower bud differentiation period>bulb inflation period>garlic bolt elongation phase>seedling stage；selenium content and accumulation quantity of garlic increased significantly in flower bud differentiation period，and the amount of cumulativing to total selenium accumulation was 57.82%，all of that showed that flower bud differentiation period was the key period of garlic absorping selenium；the size of selenium accumulation and content at bulb inflation period in difficent organs was bulbs>stem>leaf>root in garlic.
