Abstract

Winter wheat is the main crop in Huang-Huai-Hai region.Producers can benefit from accurate simulation of winter wheat.Based on experimental data,we adjusted several param eters of ALMANAC crop growth model,and simulated the growth of winter wheat.The result shows that ALMANAC crop growth model can accurately simulate leaf area index(LAI )and the yield of winter wheat.The average ratio of simulated LAI and measured LAI is1.0552,and R 2 is0.7021,the maximum error of simulated biomass is-6.01%,and maximum error of simulated yield is-5.41%,the model can also reveal the reason s that affect the growth of winter wheat.

Key words： crop growth model; winter wheat; simulation; ALMANAC model
