摘 要： 以籼型杂交稻汕优63和粳稻武育粳3号为材料进行田间小区试验，对实时氮肥管理（RTNM）和实地氮肥管理（SSNM）的农艺表现和氮肥利用效率进行了评价。结果表明，氮空白区的水稻产量为5．5-7．4t／hm^2，说明试验田背景氮颇高。

在大田试验条件下，观察了实地氮肥管理对水稻产量和稻米品质的影响。
Under the field experiment conditions, effects of site-specific nitrogen management(SSNM)on grain yield and grain quality of rice were studied.
以代表性水稻品种为材料，研究了实地氮肥管理模式下水稻的生长发育和养分吸收规律。
With typical rice cultivars as materials, the growth and development characteristics and nutrient uptake in rice under site-specific nitrogen management (SSNM) were studied.
此外，实地氮肥管理明显提高了米粉的最高黏度、崩解值，降低了消减值，改善了稻米的食味品质。
In addition, SSNM increased peak viscosity and breakdown values and decreased setback values, resulting in an improvement in cooking quality.
