Predictive Model of Water Requirement of Paddy Rice Based on Artificial Neural Network

The prediction of water requirement of paddy rice is the bases of programming in ecnomiz irrigation.Artificialneural network which has been proved to be powerful tools in modeling nonlinear process,was applied to the prediction of water requirement of paddy rice.Based on the analysis of influence factors of water requirement of paddy rice,BP neural network models with different structure have been established and tested by real data.This model can exactly reflect the relationship with influence factors and water requirement and get precisely prediction.
