A Study of Grey Forecasting Models of Wheat Sharp Eyespot Disease

摘要：

According to grey system theory and methods, a method for forecasting and analyzing the trend of wheat sharp eyespot disease was studied in this paper. By analyzing the disease at joining stage and white ear stage, collecting disease data of nine wheat strains in the north of Henan Province and combining statistics and epidemic, two groups of regression models and gray system models were set up for forecasting the middle-short term epidemic dynamic for resistant strain and susceptible strain.
