摘要:
?通过田间试验，按尿素种类和施肥量共设7个处理，研究控释尿素对大豆农艺性状、含氮量及产量的影响。结果表明：与普通尿素相比，多肽尿素、长效缓释尿素、大颗粒尿素、硫包衣尿素提高了大豆干物质、氮素积累量、氮肥利用率及产量。多肽尿素、长效缓释尿素低氮处理对大豆干物质、氮素积累量、氮肥利用率的影响最为明显，鼓粒期干物质量分别比普通尿素提高了11.1，18.1 g，氮素积累总量比普通尿素增加了0.83±1.11 g·m-2，氮肥利用率比普通尿素增加了10.73%和15.16%；多肽尿素高氮量处理、长效缓释尿素低氮处理对大豆的增产效果最为显著，分别比普通尿素增加9.5%和11.0%。
Abstract:
?A field experiment with 7 treatments of different types of urea and several nitrogen rates was conducted to study the effects of controlledrelease urea on soybean agronomic characteristics, nitrogen contents and seed yield. Polypeptide urea(PU), longacting sustainreleased urea(LSU), large granule urea and sulfurcoated urea improved the dry matter, nitrogen accumulation, nitrogen use efficiency (NUE) and seed yield compared to the common urea. The treatments of 60 kg〖DK1〗·ha-1 PU and LSU increased dry matter, total accumulated nitrogen and NUE obviously, and at the pod filling stage, the three indexes increased by 11.1 and 18.1 g·m-2, 0.83 and 1.11 g·m-2, 10.73% and 15.16%, respectively. The treatments of 75 kg·ha-1PU and 60 kg·ha-1? LSU had best yieldincreasing effect, and seed yield increased by 9.5% and 11.0%, respectively.
