| 摘 要： | 为了提高优质稻整精米率,寻找其最佳的肥料运筹技术,采用三元二次回归正交旋转组合设计,研究了施氮量、有机肥施用比例与基肥施用比例三因素对优质稻湘晚籼13号整精米率的影响.寻优结果表明:该品种高整精米率的最优肥料运筹方案是施纯氮180 kg/hm2,有机肥施用比例为66%,基肥施用比例为53%.

| Abstract: | In order to increase the head rice rate of good-quality rice variety,and explore the optimum fertilizer application techniques,by means of the twice power of three variable quadratic orthogonal regressive rotation combination designed,effects of three factors (utilizing the quantity of nitrogen fertilizer,organic fertilizer proportion and base fertilizer proportion) on the head rice rate of the good-quality rice variety Xiang wan xian 13 were studied.The results showed that the optimum fertilizer application of this variety was the quantity of nitrogen fertilizer 180 kg/hm2,organic fertilizer proportion 66% and base fertilizer proportion 53%. |
