| 摘 要： | 桃优香占是桃源县农业科学研究所选育的高档优质杂交晚籼中熟新组合,为了掌握该组合氮肥运筹规律,2015年进行氮肥用量试验,2016年进行氮肥运筹技术研究。2015年试验施纯N 120~210 kg/hm~2,随着氮素增加,单产提高,说明该组合耐肥性较强,对氮的需求较高。2016年试验施用量为纯N 180 kg/hm~2,P_2O_5 30 kg/hm~2,K_2O 135 kg/hm~2,氮肥按照基∶蘖∶穗肥比为5∶2∶3施肥方式,效果最好,单产最高。

| Abstract: | Taoyouxiangzhan is a high quality late season indica hybrid rice combination, in order to master the law of nitrogen management in this combination, nitrogen amount test was conducted in 2015 and nitrogen management technique was studied in 2016. In 2015, the trial applied pure nitrogen 120 to 210 kg/hm2, with the increase of nitrogen, the yield per unit area increased, it proved that the fertilizer resistance of this combination was stronger, and the demand for nitrogen was higher.In 2016, the trial applied pure nitrogen 180 kg/hm2, P2O530 kg/hm2, K2O 135 kg/hm2, N fertilizer applied as base fertilizer : tillering fertilizer : panicle fertilizer by 5:2:3, then came with the best effect, the highest yield per unit area. |
