| 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。

| Abstract: | 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 significan... |
