STUDIES ON EFFECT OF FERTILIZER APPLICATION TO THE FORMATION IN YIELD AND QUALITY OF WINTER WHEAT Ⅰ.Influnce of the top dressing with nitrogen stage to the synchronous formation between yield and quality
This article mainly shows the following questions: (1) The highest wheatyield is at the two nitrogen dressing period that is the stage of gettingup and elongation. Applying nitrogen fertilizer before getting up stage canmainly increase spike number. Applying nitrogen at the getting up stage andelongation stage not only increase spike number but increase the grain num-ber per spike. Applying fertilizer after elongation mainly adds the grainweight. (2) The protein content of the grain is raising with applying...
