Abstract：Field experiments were conducted to investigate the effects of silicon fertilizer in various appli-cation ways on prevention and control of wheat powdery mildew , grain starch content and farinographical prop-erties with the cultivars Xinong 979 and Zhoumai 18 as experimental materials .The results showed that the disease index was decreased and the disease resistance was increased significantly under the silicon fertilization treatments, especially the treatment of bottom fertilization +foliar application at flag stage;the control effect of powdery mildew at late grain -filling stage was the best .The silicon fertilization treatments could increase the contents of total starch and amylopectin , and water absorption of flour , prolong the time of dough development and stability , but decrease the amylose content and weakening degree .The contents of total starch and amyl-opectin increased by 10 .4%and 24 .7%respectively under the treatment of bottom fertilization +foliar appli-cation at flag stage .
