摘要
以单季常规晚粳稻‘秀水134’为供试水稻品种,在田间条件下,研究了传统水作及覆膜旱作下包膜控释尿素对水稻产量及氮肥利用率的影响。结果表明:(1)在覆膜旱作与传统水作条件下,与普通尿素PU100%(N 180 kg.hm-2)处理相比,施用等氮量硫磺加树脂双包膜尿素SPCU 100%产量分别为7 781和7 775 kg.hm-2,显著提高5.7%和9.7%;氮肥利用率分别为57.2%和35.5%,显著提高110.3%和78.4%;氮肥农学效率也有显著性提高。(2)与传统水作相比,覆膜旱作条件下,除PU 100%处理外,其他各对应施肥处理产量差异不显著;氮肥利用率显著提高。
A field experiment was conducted to determine effects of controlled-release coated urea on grain yields and nitrogen use efficiency of rice variety Xiushui 134 under traditional flooding cultivation and non-flooded plastic film mulching cultivation.The results showed that the rice grain yields of single basal application of sulfur-polyester resin-coated urea（SPCU 100%）under the non-flooded mulching and traditional flooding cultivation were increased by 5.7 and 9.7%（P
