| 摘 要： | 对马铃薯(Solanum tuberosum L.)进行水肥耦合盆栽试验,采用4因素补水量、施氮(N)量、施磷(P5O2)量、施钾(K2O)量]5水平二次回归正交旋转组合试验设计,研究了马铃薯生长的典型时期——初花期的生长量对产量的影响,建立了马铃薯生长量与产量的关系方程。结果表明,当初花期的株高为34 cm,茎粗为0.54 cm,叶面积为55.06 cm2时产量最大,达到857 g/盆。

Effects of Potato Growth on the Output under Water and Fertilizer Coupling |
| |
| Abstract: | The study was conducted to research the effect of potato growth on potato output during the typical period of potato growing. The experiment was designed with 4 factors including irrigation norm, nitrogenous fertilizer, phosphate fertilizer, and potash fertilizer with 5 levels quadratic regression orthogonal rotating combinatorial design. The regression models were established between potato output and growth by regression. The results showed that the potato output would achieve 857 g/pot when the plant height was 34 cm, stem diameter was 0.54 cm, and leaf area was 55.06 cm2. |
