| 摘 要： | 氮素对超级稻的产量及各种性状有重要的影响。试验结果表明：在不同施氮量的处理中，差异显著，在中等地力条件下每667m^2施氮10-18kg，超级稻的分蘖数、有效穗数、穗粒数、产量等因素随施氮量的增加而增加，以施用18kg／667m^2氮素处理的产量最高，比对照增产46．4％。

| Abstract: | Nitrogen has a significant inpact on the output and its various characters of Super rice.The experimental results show that at the medium soil fertility condition,the Super rice's tillers,effective panicles,grains per spike,output etc.have been increased along with the application inerease of nitrogen from 10 to 18kg/667m2.Comparing with the control group,the output will increase 46.4% to reach the highest level when 18kg/667m2 nitrogen used. |
