Abstract: To determine the yield and quality effects of applying period and times of foliar fertilizer of strong gluten wheat were studied. The chlorophyll content of flag leaves,yield and quality of grain were analyzed under different treatments by random experiment of two factors and spraying times. The results showed that the chlorophyll content of flag leave was increased when spraying foliar fertilizer before winter and at jointing stage. And the chlorophyll content of flag leaves reached a maximum when praying foliar fertilizer at three stages. From the yield perspective,the best time of spraying foliar fertilizer was seedling stage and jointing stage,and spraying three times before winter,at the jointing and filling stage could improve the yield of wheat significantly. From the quality perspective,the quality of spraying foliar fertilizer could improve the quality of wheat,especially at jointing stage and heading stage. Spraying foliar fertilizer at jointing,heading and filling stage could increase the yield, however,it could debase the quality.

Key words: strong gluten wheat, foliar fertilizer, yield, quality
