| 摘 要： | 研究了3种施肥水平对2个杂交水稻品种产量及其构成因素的影响。结果表明：粤优589收割产量与分蘖数、有效穗之间存在着正相关系，红泰优996收割产量与有效穗、结实率之间存在正相关系，两品种收割产量均与每穗粒数存在一定的负相关系；3种施肥水平之间的产量无显著差异，随着施肥量的增加，粤优589收割产量均有增加的趋势，而红泰优996收割产量开始下降，然后升高。

| Abstract: | The effects of 3 fertilizer application rates on yield and yield components of 2 Hybrid rice varieties were studied. The results showed that tiller and effective panicle number has positive correlation with yield for Yueyou 589, effective panicle number and seed setting rate has positive correlation with yield for Hongtaiyou 996, however, spikes per panicle has negative correlation with yield for both varieties. No significant yield differences under 3 fertilizer application rates, with increase of fertilization, yield of Yueyou 589 has an increasing trend, but yield of Hongtaiyou 996 was decreased at first, and then increased. |
