Abstract
A field experiment with split plot design was carried out to study effects of postponing nitrogen application and spraying foliar 6- BA after anthesis on grain yield and quality of winter wheat in 2010- 2011 growing seasons using the variety of Yannong 19 with the total amount of nitrogen being 240 kg hm- 2. The results showed that both postponing nitrogen application and spraying foliar 6- BA after anthesis improved activities of GS,GPT,SSS in grain of winter wheat significantly,while had no significant effect on GBSS activity in grain of winter wheat. Postponing nitrogen application significantly improved grains per spike,1000- grain weight and grain yield,and spraying foliar 6- BA after anthesis significantly increased 1000- grain weight and grain yield. Both postponing nitrogen application and spraying foliar 6- BA after anthesis improved protein content and each protein ingredient content,Glu / Gli ratio,protein accumulation,starch content, amylopectin content, amylopectin / amylose ratio and starch accumulation in grain significantly. Spraying foliar 6- BA after anthesis promoted the effects of postponing nitrogen application. Under the condition of this experiment,the treatment B1N4( base fertilizer: elongation fertilizer: booting fertilizer = 3: 5: 2, spraying foliar 6- BA after anthesis with the concentration of 10 mg L- 1and the volume of 100mL m- 2) had the optimal effect on the improvement of the yield and quality of winter wheat.
