为提高毕节市马铃薯栽培水平，促进马铃薯产业的持续发展，采用四元二次回归正交旋转组合设计方法，对影响马铃薯高产超高产的主要栽培因子进行研究。结果表明：各试验因子对产量的影响作用依次为施钾水平＞种植密度＞施氮水平＞施磷水平。增施钾肥、提高种植密度和合理施用氮磷肥是获得高产超高产的技术关键环节。通过计算机模拟寻优，提出毕节市马铃薯产量在3500 kg／667m2以上的栽培技术措施：种植密度5181～5819窝／667m2，纯 N 用量6．72～7．82 kg／667m2，P2 O5用量10．06～16．9 kg／667m2，K2 O 用量22．72～28．18 kg／667m2，N∶P2 O5∶K2 O＝1∶1．85∶3．50。

Main cultivation factors to influence high yield of potato were studied by using the quaternary quadratic orthogonal regression rotational combination design to improve potato cultivation level and promote sustainable development of potato industry in Bijie City.The results showed that main factors to influence potato yield are potassium level > planting density > nitrogen level > phosphorus level.Increasing potassium level and planting density and rationally applying nitrogen and phosphorus fertilizer are the key technological links to gain super-high yield of potato.The cultivation technical measures for potato yield to gain 3 500 kg/667m2 are 5181~5819 holes/667m2 ,6.72~7.82kg/667m2 N, 10.06~16.9kg/667m2 P2 O5,and 22.72~28.18kg/667m2 K2 O.N ∶ P2 O5 ∶ K2 O is 1∶1.85 ∶ 3.50.
