Application of grey Verhulst model in pesticide residues prediction
Pages: 135-138
Year: Issue:  5
Journal: Journal of Agricultural University of Hebei

Keyword:  Verhulst model Chlorpyrifos prediction pesticide residues;
Abstract: 介绍了灰色Verhulst模型的原理与检验方法,以毒死蜱在苹果中的残留量作为原始数据序列,利用Matlab编程为实验平台,建立了瓜果蔬菜中农药残留量的Verhulst预测模型,并与负指数模型进行比较.结果表明:所建的Verhulst预测模型具有较高的精度,可以准确的预测出瓜果蔬菜中的农药残留量,为人们的健康饮食提供科学的依据.
