%X Investigation and analysis of source-sink-translocation characteristics of winter wheat were conducted for 2005~2007 in 15 high-yield fields of Longkou and Laizhou Cities, Shandong Province. The high-yield winter wheat colony under Stabilizing LAI-Controlling Plant Type-Increasing Ear Number (CPCE) management exhibits higher non-leaf area proportion, total photosynthetic area, number of grain and vascular bundle. It has the advantages of increased source, expended sink and smooth translocation. In order to produce 9 000 kg·hm-2 gain yield of winter wheat, it is necessary to maintain total photosynthetic area at 10~13 m2·m-2 and non-leaf/leaf area ratio at 1.3~1.7 during flowering stage; and aboveground wheat dry-matter at 19 500 kg·hm-2, economic coefficient higher than 0.45, total colony bundle number at 22×103~30×103·hm-2, daily conducting amount at 230 kg·hm-2 and conducting amount per bundle at 1 mg·d-1 during mature stage. The comprehensive analysis of the balance between source and sink of high-yield wheat fields shows that CPCE benefits increasing photosynthetic source of wheat.
