摘要

Abstract

Duality quadratic saturating D-optimum design was carried out under pot experiment to study the interaction of N fertilizer and water coupling at a given level of P and K.The results showed that the threshold value existed in water-fertilizer interaction.The optimal scheme of water-fertilizer interaction under objectives was worked out by computer simulation on a mathematical model which was established based on the result of experiment.
