| 摘 要： | 采用二次回归正交设计的方法,研究了定西市加工型马铃薯品种大西洋的氮肥、磷肥、钾肥施用量和种植密度与产量间的关系,建立了其因素与产量的最优回归模型。对试验数据进行灰色关联度分析的结果表明,方案25的灰色关联度为0.741,居参试方案之首,因此马铃薯品种大西洋在定西市的高产栽培技术措施为:纯氮X1=112.5(kg.hm-2)、纯磷(P2O5)X2=112.5(kg.hm-2)、纯钾(K2O)X3=135.0(kg.hm-2),密度X4=60000(株.hm-2)。

| Abstract: | the quadratic regressive factorial experiment was used to study the relationship between nitrogenous fertilizer,phosphate fertilizer,potash fertilizer,plant density and tuber yield for the potato cultivar Atlantic grown in Dingxi Gansu.The optimal regression model was created between the factors and yield.The result of grey relational analysis using the testing data indicated that the grey relational degree of the treatment 25 was 0.741,being the highest in this experiment.Therefore,the technical measures for high-yielding culture of the potato cultivar Atlantic grown in Dingxi Gansu was: pure nitrogen x1 = 112.5(kg·hm-2),pure phosphorus(P2O5) x2 = 112.5(kg·hm-2),pure potassium(K2O) x3 = 135.0(kg·hm-2),and density x4 = 60 000(hill·hm-2). |
