摘　　要：以“垦农4号”为材料,在大田小区试验的条件下,研究在初花期叶面喷施EDTA-Mn对大豆叶片光合特性及叶绿体色素的影响。结果表明:适宜浓度的锰叶面喷施能提高大豆叶片的光合速率、蒸腾速率及水分利用效率;增大叶片的气孔导度和气孔相对开度;增加了叶绿素a、叶绿素b及叶绿素总量,类胡萝卜素含量有所降低。较高浓度锰叶面喷施可对上述指标起到显著的抑制作用。After spraying EDTA-Mn, photosynthesis character and chlorophyll pigment of K4 in initial bloom stage were researched in this article. The results showed spraying fitting concentration manganese to leaves could improve the photosynthesis velocity and transpiration velocity, enhance the water use efficiency; enlarge the stomatal conductance and the stomatal relative aperture of leaves, increase the content of chlorophyll a and b, decrease the content of carotenoid. But excessive spraying manganese would restrain these indexes obviously.
