Abstract: To investigate the effects of drip irrigation lateral placements on dry matter accumulation, distribution and translocation of winter wheat, a field experiment were conducted using qingmai 7 hao cultivar with four drip irrigation treatments (1 lateral 3 rows (T3), 1 lateral 4 rows (T4), 1 lateral 5 rows (T5) and 1 lateral 6 rows, using no irrigation as control CK) under the same irrigation quota (1800 m3/hm2) at experimental station of Qingdao University in the year of 2011-2012. The results showed that, compared with CK, the grain dry weight in the harvest and filling rate in the late filling of winter wheat were significantly increased. The distribution rate in grain of dry matter in the mature period and the contribution to grains of dry matter accumulation after anthesis were increased significantly. There were different effect among the four drip irrigation treatments on grain filling, dry matter accumulation and translocation. The filling rate and grain dry weight in the late filling of T5 were higher than other drip irrigation treatments. Dynamic change of the total dry matter accumulation of winter wheat showed a “S” curve. The distribution rate in grain of dry matter in the mature period was T4 > T5 > T6 > T3 > CK, and there were significantly difference. The contribution rate of dry matter after anthesis to grains was T5 > T4 > T6 > T3 > CK, T5 reached 58.86% significantly higher than others. Therefore, “1 lateral 5 rows” pattern was most conductive to grain filling and significantly improved accumulation of photosynthetic organs assimilates after anthesis, got higher grain yield.
