摘 要:为探索在马铃薯黑膜覆盖打孔栽培技术条件下密度与N、P、K三要素配比对产量的影响,通过四因素二次回归正交旋转组合设计,运用DPS数据处理分析软件,建立了黔东南地区脱毒马铃薯费乌瑞它在黑膜覆打孔栽培技术条件下的产量与密度及N、P、K施用量等农艺措施关系的数学模型。结果得出黔东南地区黑膜覆盖打孔栽培技术条件下脱毒马铃薯高产栽培最佳技术方案为:密度6302~6540穴/667m2,施纯氮量13.36~14.64kg/667m2,施P2O5量9.15~10.85kg/667m2,施K2O量11.11~13.75 kg/667m2。In order to explore the effect of density and N,P and K ratios on yield of potato under black film covering and perforating cultivation techniques,four-factor quadratic regression orthogonal rotation combination was designed,and DPS data processing analysis software was used to established a mathematical model for the relationship among yield and density and N,P,K application rates of detoxified potato favorit in Qiandongnan under the conditions of black membrane perforation cultivation. It was concluded that the best technical scheme for high-yield cultivation of virus-free potato under the condition of black film covering and punching cultivation technology in southeastern Guizhou is : density is between 6302 plants/667 m2 to 6540 plants/667 m2,nitrogen Application amount is between 13. 36 kg/667 m2 to 14. 64 kg/667 m2,Phosphate fertilizer amount is between 9. 15 kg/667 m2 to 10. 85 kg/667 m2,Potash amount is between 11. 11 kg/667 m2 to 13. 75 kg/667 m2.
