| 摘 要： | 本研究在晋西北河曲县砖窑沟试验区设置了正交旋转组合设计试验，建立了新修梯田培肥增产配套措施的数学模型。通过对模型的分析与模拟选优，找出了新修梯田种植马铃薯配套措施的较优组合是:施纯氮8—12kg/亩，施磷<6kg/亩，施有机肥2600—4000kg/亩，播种密度2300—2800株/亩，亩产薯块可达到1000—1600kg。

| Abstract: | This field experiment of orthogonal rotation combination design was carried out at Zhuanyaogou basin experimental area of Hequ county in northwestern Shanxi.Based on experimental results,a comprehensive measure mathematical model of increasing soil fertility and yield on new terraced fields was established.On the analysis and optimization of model, it can be found that the better comprehensive moasures of planting potato on new terraced fieIds are that: nitrogen fertilizer (N) is 8-12kg/mu, phosphate fertilizer (P2O5) less than 6kg/mu, organic fertilizer 2600-4000kg/mu and planting density 2300-2800 plants/mu, thus potato yield can reach 1000-1600kg/mu. |
