| 摘 要： | 在品种和施氮量相同的条件下,施氮方法对植株吸氮有很大影响.前期控氮,中期补施穗肥的方法可延长植株吸氮高峰持续时间,增加植株氮素总积累量,对防止植株早衰,增加稻谷产量,提高氮肥利用率,都有良好的作用.

| Abstract: | The nutrient' s uptake characteristics of rice and application methods of nitrogen fertilizer were studied in 1996-1999. The results showed that:The N uptake characteristics of rice were influenced remarkably by application methods of N fertilizer under other conditions identical.When part of N fertilizer was applied at middle growth stage, the amount N absorbed was more and the heavy absorb period was longer, the yield was higher and the N use efficiency was higher than the treast-ment of all N applied as basal fertilizer. |
