Abstract: Neural network is one of fastest developing information processing techniques in artificiaintelligence. It is a new form of computing,inspired by biological and a mathematical model com-posed of a. large a umber of processing elements organized into layers, which can be used to solvecomplex,fuzzy and non-lmear problems.In this paper, the basic structure of neural network isbriefly introduced and the application of neural network in agricultural engineering is summarized.
