摘　　要：采用框栽和大田对比试验相结合的方法,研究硫包膜尿素(SU)对大豆干物质积累和产量的影响。框栽试验结果表明,在相同氮水平条件下,施用硫包膜尿素的大豆干物质积累量与一次性施尿素(N75)和追肥处理(N25*3)相比,分别增加24.3%和19.7%。施用硫包膜尿素产量比施用尿素增加16%,与追肥处理差异不显著。大田试验结果表明,施用硫包膜尿素的大豆干物质积累量比一次性施用尿素处理高12.2%,产量增加7.3%。框栽和大田试验结果一致,由此可知,施用硫包膜尿素能够增加大豆干物质积累量和产量。Frame culture and field experiments were conducted to study the effects of sulfur-coated urea on dry matter accumulation and yield of soybean. The results of frame culture showed that the dry matter accumulation of soybean applied sulfur-coated urea （SU） was 24.3% and 19.7% higher than those of soybean with common urea （N75） and topdressing treatment （N25＂3）. Yield of soybeans applied sulfur-coated urea （SU） was increased by 16% compared with that of soybean with the common urea （N75）, while there was no significant difference between SU and N25＂3 treatments. The results of field experiment showed that the dry matter accumulation and yield of soybean applied St J, compared with the control treatment （CK） increased by 12.2% and 7.3%, respectively. The results of frame culture and field experiments consistently showed that application of sulfur-coated urea in soybean could increase the dry matter accumulation and its yield.
