摘要: 采用三因素二次饱和D最优设计方案,对中棚番茄氮磷钾最优化施肥问题进行了定量研究,建立了中棚番茄产量形成的肥料反应模式,利用回归模式对最优化施肥量、各种肥料要素的单独产量的效应规律及其互作效应进行了探讨。

关键词: 番茄, 氮, 磷, 钾, 配方施肥

Abstract: The devices of 3 factors and 2 powers saturation D were adopted in this test. Using urea, calcium superphosphate and potassium chloyide, we had quantitative studies on the issues of the optimum applying fertilizer-N, P, K and set up reaction model of fertilizer for tomato yields in the middle sheds. The optimum feritilizer dose, reaction law for output to every kind of fertilizers and interaction law were probed into respectively according to regression model.

Key words: Tomato, N, P, K, Rational fertilizing
