| 摘 要： | 施氮时期对不同处理两个品种水稻产量影响差异很大,方差分析FV7=38.27**;FV10=19.01**;都达到了极显著水平。大穗型水稻V7的处理1(基肥)产量最高,分别比其它处理(3,2,4)增产9.64%,12.22%,14.96%。穗数型水稻V10的处理2(基肥+蘖肥)产量最高,分别比其它处理(3,4,1)增产6.35%,13.03%,19.08%。施氮时期对水稻蛋白质的含量影响明显,两个品种水稻均以处理3(基肥+穗肥)蛋白质含量最高,其次是施粒肥。随着施氮时期的后移,水稻直链淀粉的含量有下降趋势。

| Abstract: | The research results indicate that the effect of nitrogen application time on the yield of both varieties was significant, FV7=38.27**, FV10=19.01** respectively. For V7, the highest yield was from base fertilizer, increased rice yield 9.64%, 12.22%, 14.96% than other treatments. And for V10, the highest yield occurred in the treatment of base + tillering fertilization, increased rice yield 6.35%, 13.03%, 19.08% than other treatments. In general, nitrogen application at later growth stage results in higher protein content and lower amylose content. |
