摘　　要：在池栽条件下研究了 3个不同密度处理对 2个冬小麦品种 (系 )品质和产量的影响。结果表明 ,适当降低密度 ,籽粒品质改善 ,产量提高。本试验条件下 ,“5 0 9”以每 6 6 6 7m2 基本苗 10万 ,“93- 5 2”以每6 6 6 7m2 基本苗Effects of different densities on grain quality and yield in winter wheat were studied under pondlet culture condition. The results showed that decreasing the number of plants of winter wheat in certain range could increase the grain quality and yield. In the condition of this experiment, it is the best scheme which takes account of quality and yield for wheat varieties (strains) 509 and 93-52 to sow 150×10~4/hm^2 and 90×10~4/hm^2 of plants respectively.
