摘　　要：锰在植物生理活动过程中作用甚为广泛，锰可提高碳水化合物的同化作用和呼吸强度，促进酶的活性．影响氮素代谢，是植物生长发育中必不可少的矿质元素之一，油菜缺锰会导致植株矮小，生长衰弱，开花数及角果数减少，芥菜型油茶缺锰不能开花结实。研究表明，苗期适量施用锰肥可以促进油菜的生长发育，增技增果增粒，提高产量，改善品质。Mangnese Plays extensive parts in plant physiology. It is essential for its effects in assimilation and respiration, in en hancing enzyme activities and nitrogen metabolism. Rape plants in short of mangnese represent dwarf stature, slower growth, less flowers and fruits, and even sterility in Brassica juncea. This study showed, that application of mangnese at seedling could enhance growth and development and resulted in more branches, fruits and seeds, higher yield and better quality
