【Abstract】 Applying"SHUANG XIAO" microelement fertilizer to maize at multiple experimental plots in one year, the result show that it promotes nutritional growth of maize, increases height、 thickness of stem, width of leaf and the numbers of roots. It also makes maize precocity and shorten 2～5 days;It promotes reproductive growth of maize, increases kernels/ear and 100 - grains-weight. The averge yield of increase is 14.61 % ;Spraying it on leaf can prevent and control northern leaf blight of corn; The effect of prevention and control is 50 % ; The best way of using is seed treatment and spraying it on leaf at jionting stage.更多还原
