| 摘 要： | 以武香粳14为供试材料,研究精确施氮和常规施氮对水稻产量与氮肥利用率的影响。结果表明,精确施氮处理的穗数极显著地低于常规施氮处理;精确施氮处理的水稻产量高于常规施氮处理,但未达到显著水平;精确施氮处理的氮肥当季利用率比常规施氮处理高8.8%。

| Abstract: | Using wuxiangjing 14 as a material,effects about precise-using N and normal using N to the rice yield and N using efficiency were studied.The result showed that the panicles of precise-using N were remarkable fewer than the panicles of normal using N,the rice yield of precise-using N was unremarkable higher than that of normal-using N.The N using efficiency of precise-using N was more than that of normal-using N by 8.8%. |

| Keywords: | precise-using N normal using N rice yield N using efficiency |
