摘要：
Techniques of Operations Research were introduced into the modelling work for determining optimal NPK-fertilizer requirements for vegetable crops which lead not only to a maximal yield but also to a special crop quality. In the model applied, 26 plant parameters were adopted to described yield and quality responses of Chinese cabbage to different NPK-nutrition. An integrative and comprehensive analysis about relationships between plant growth and nutrient supply can be carried out by using this model. Examples of model calculation for practical use, the validity of the model and a comparison of methods for fertilizer determination were demonstrated and discussed.
