| 摘 要： | 通过田间小区试验,比较了不同控释氮肥对水稻产量和氮肥利用率的影响。结果表明,不同控释氮肥处理水稻增产和提高氮肥利用率的效果不同。硫磺树脂包膜氮肥处理水稻产量和氮肥利用率显著高于其他处理。不同控释氮肥处理比普通氮肥处理显著提高水稻氮肥利用率,增幅为7.23～14.83个百分点。硫磺树脂包膜氮肥处理比其他处理提高了水稻总粒数和结实率。因此,硫磺树脂包膜氮肥处理在该地区水稻施用效果最佳。

| Abstract: | Field plot experiment was conducted to compare the different controlled-release nitrogen fertilizers on yield and nitrogen utilization rate of rice.Results showed that there were different results on yield and nitrogen utilization rate of rice applied of different controlled-release nitrogen fertilizers.The highest yield and nitrogen utilization rate of rice was applied of controlled-release sulfur polyolefin-coated urea.Nitrogen utilization rate was increased significantly by 7.23% to 14.83% by the applyin... |
