【Abstract】 Applying the BP feed forward of artificial neural network model and improved BP arithmetic, we could predicate the occurring degree of cotton bollworm. The results indicated that this arithmetic was reliable and the validate accord rate could reach 100%, so it had the wide application foreground in the forecast of crop plant diseases and insect pests.更多还原
