Abstract：The effects of seeding quantity on grain yield and population characters of wheat under wide -precision planting in field were studied in 8 cities of Shandong Province.Jimai 22 was selected as experimental material and 5 kinds of seeding quantity were designed .The results showed that with the increase of seeding quantity, the number of stems per unit area in the whole growth period increased significantly , and the tillers, secondary roots and percentage of earbearing tillers per plant decreased ; the grain yield increased firstly and then decreased.The grain yield increased significantly at the seeding quantity of 150 kg/hm 2 compared with 2 , but it could not increase significantly when the seeding quantity increased from 150 kg/hm 2 to 2252 .In conclusion, the suitable seeding quantity for this test area was 15 kg/hm 2 , and the suitable range 75 kg/hm kg/hm of basic seedlings was about 2570 thousand per hectare.
