Field experiments of controlling wheat diseases by increasing K fertilizer and controlling N fertilizer;

The influence of wheat straw covering and water saving on wheat diseases during the whole growth period;

The Wheat Diseases Expert System Based on the Web and the Implemention using the Java Technology;

he effects of triadimefon as a seed dressing for controlling wheat disease on yield components were different in the field experiments.

In order to obtain pellucid knowledge from neural network, this paper takes wheat disease diagnosis as case to study BP neural network ruler extract, and proposes a new method to extract BP neural network ruler base on structure analysis.
