| 摘 要： | 试验采用 311改良饱和D设计方法 ,对青海省新育成的青薯 2号 (32 8)品种进行了氮、磷、钾三大要素的施肥水平研究。其结果表明 :三种化肥对产量影响的大小程度依次排序为N >K >P。经计算机模拟寻优 ,获得了施肥的高产数学模型和最佳农艺措施组合方案。 6 6 7m2 产量高于2 6 0 0kg的最优方案有 18套 ,最佳农艺措施是 :氮肥用量为 2 8 97～ 2 9 15kg ,钾肥用量为 16 5 4～17 11kg ,磷肥用量为 5 34～ 5 88kg。 |

| Abstract: | Using 311 D saturation design,effects of levels of nitrogen(x 1) phosphorus(x 2) and potassium(x 3)on gettng high tuder yield of the potato cultiver Qingshu2 were studied.The results showed that the importance of fertilizer for potato tuber yield was N>P>K.High yield mathemtical model and agronomic measure for gething a potato yield of 2600 kg/667 2 or more were obtained by computer simulation.The best agronomy measure was N:28 97～29 15 kg,P:5 34～5 88 kg,K:6 54～17 11 kg. |
| Keywords: | potato level of N P K 311 D saturation design excellent plan |
