| 摘 要： | 通过两年的试验研究，利用二次通用旋转设计原理建立了氮肥（x1）、磷肥（x2）和栽培密度（x3）与陇薯6号产量（y）的回归方程，对方程进一步分析表明，各因素对产量影响的大小顺序是氮肥〉密度〉磷肥。陇薯6号产量大于39t／hm^2的栽培方案是：施纯氮122．56t／hm^2～177．50t／hm^2、磷102．74t/hm^2～167．26L／hm^2，栽培密度为52861株／／hm^2～60580株／hm^2（行距60cm，株距27．5cm～31．5cm）。图4，表4，参7。

| Abstract: | A mathematic model, Y=43.7391 + 0.16467X_3 - 2.8378X_1~2 - 1.4274X_2~2 - 2.6231 X~3_2,with the application of nitrogen( X_1) ,phos-phorus(X_2), planting density(X_3) and the yeild of Longshu 6 (Y) had been built by the quadratic general rotational combination design based on two year's study. The further analysis results showed thai the order that influenced the yield is nitrogen( X_1) > planting density( X_3) > phos-phorus(X_2).The cultivation scheme that the yield is higher than 39 t/hm~2 is pure N 122.56 kg/hm~2 - 177.50 kg/hm~2,P_2O_5102.74 kg/hm~2 -167.26 kg/hm~2,52 861 - 60 580 plant/hm~2(row spacing 60 cm,plant spacing during 27.5 cm- 31.5cm). |
