摘要:
为了制定毕薯5号高产栽培技术，以毕薯5号为材料，采用4因素5水平二次回归正交旋转组合设计方法，实施不同种植密度以及氮、磷、钾施用量影响马铃薯主要农艺性状的试验研究。结果表明：各栽培因子影响马铃薯单株产量的顺序为密度>磷肥>钾肥>氮肥，影响马铃薯单株结薯数的顺序为密度>钾肥>磷肥>氮肥，影响马铃薯商品薯率的顺序为磷肥>氮肥>钾肥>密度。当密度为54 485.40株?hm2，施氮肥459.34 kg?hm-2、磷肥590.09 kg?hm-2、钾肥454.08 kg?hm-2时，可获得最高单株产量为718 g；当密度为34 ?434.60株?hm-2，施氮肥432.18 kg?hm-2、磷肥735.08 kg?hm-2、钾肥286.98 kg?hm-2时，可获得最多单株结薯数为14.8个；当密度为58 527.90株?hm-2，施氮肥1 011.48 kg?hm-2、磷肥2 614.89 kg?hm-2、钾肥437.60 kg?hm-2时，可获得最高商品薯率为71.18%。
Abstract:
In order to make high yield cultivation techniques of potato Bishu 5,the quadric orthogonal rotational regression design of 4 factors and 5 levels was used to study the effects of fertilizer quantity and planting density on main agronomic trait of potato Bishu 5.The results showed that the effect order of all cultivation factors on yield per plant was density>P>K>N,the effect order of all cultivation factors on tuber number per plant was density>K>P>N,the effect order of all cultivation factors on commodity potato rate was P>N>K>density.The highest yield per plant of 718 g would be obtained under the cultivation conditions of 54 485.40 plants?hm-2,N fertilizer 459.34 kg?hm-2,P fertilizer 590.09 kg?hm-2,K fertilizer 454.08 kg?hm-2.The highest tuber number per plant of 14.8 would be obtained under the cultivation conditions of 34 434.60 plants?hm-2,N fertilizer 432.18 kg?hm-2,P fertilizer 735.08 kg?hm-2,K fertilizer 286.98 kg?hm-2.The highest commodity potato rate of 71.18% would be obtained under the cultivation conditions of 58 527.90 plants?hm-2,N fertilizer 1 011.48 kg?hm-2,P fertilizer 2 614.89 kg?hm-2,K fertilizer 437.60 kg?hm-2.potato; planting density; N,P and K fertilizer; agronomic trait
