试验采用二次通用旋转组合回归设计方法,对温室黄瓜氮磷钾最优化施肥问题进行了定量研究,建立了温室黄瓜产量形成的肥料反应模式,利用回归模式对最优施肥剂量、各种肥料要素的单独产量反应规律及其互作效应进行了探讨。
In the experiment, the quadratic universal rotary combination regression design method was used to quantitatively study the optimal fertilization of nitrogen, phosphorus and potassium in greenhouse cucumber. The model of fertilizer response to greenhouse cucumber yield was established and the optimal fertilization dose, The individual yield reaction law and its interaction effect were discussed.
