| 摘 要： | 通过2008年在肥东花生原种场进行田间小区试验，研究了不同包膜控释尿素不同用量对花生产量和氮肥利用率的影响。结果表明，金正大包膜控释尿素增产效果显著。在等氮条件下，与普通尿素相比，SPCU100%和PCU100%分别增产15.6%和13.00%，氮素利用率分别为51.14%和54.92%；SPCU70%和PCU70%分别增产9.66%和23.12%，氮素利用率分别为48.36%和60.87%。金正大包膜控释尿素一次性在花生上基施具有增效、节肥、省工的特点。此外，金正大包膜控释肥还可以改善花生农艺性状。金正大树脂包膜控释尿素减氮30%施用，在花生上应用效果最好。 |

| Abstract: | In 2008,field plot experiments were conducted to investigate the effects of controlled-releases coated urea on peanut yield and apparent N recovery rates at peanut foundation seed farm,Feidong with 810-3 variety.The results showed that in comparison with common urea,especially with the equal content of nitrogen,SPCU100%and PCU100%increased by 15.6%,13.00%respectively,the yield difference was significant;SPCU70%and PCU70%increased by9.66%,23.12%respectively,the yield difference of PCU was very significant;th... |
