摘　　要：为了了解不同微肥对苏丹草新品系营养生长和种子产量的影响,采用随机田间小区试验的研究方法,比较处理和对照间差异显著性。结果表明:钼具有促使苏丹草提前出苗的作用,与对照比,其全生育期相应缩短了10 d。镁、锌、钼均具有一定使叶宽度增加的作用,3个处理间的差异显著(P<0.05),锌和钼的作用相当,它们比镁的作用强。镁和锌均能促使茎粗有所增加,且处理与对照间差异显著(P<0.05)。施镁、锌、钼均使种子产量有所增加,处理间与对照比均为差异显著(P<0.05),锌和钼的作用均比镁明显。本研究表明在播种时施入适量含锌和钼元素的微肥对苏丹草茎粗、叶宽及种子产量的增加均具有一定的促进作用。In order to understand the effect of application of microelement fertilizers on agronomic characters and yield to Sudan grass. Combination research methods of field plot test observation outdoor were carry out. The results show that the molybdenum has prompted Sudan grass early emergence, the whole preriod was shortened about 10 days. Magnesium, zinc, molybdenum has a certain increase the leaf width, the significant difference between the three（P〈0.05）, the effect of zinc and molybdenum, they are better than the effect of magnesium. Magnesium and zinc can cause stem diameter increased, and a significant difference between treatment and control group（P〈0.05 ）. Magnesium, zinc and molybdenum are resulting in increasing seed production, between treatment and control group were significant difference （P〈0.05）, the effect of zinc and molybdenum than magnesium. This study suggests that zinc and molybdenum microelement fertilizer have a certain role in promoting Sudan grass stem diameter, leaf width and seed yield to been increased all.
