基于质量控制图的蔬菜中矮壮素和赤霉素残留预警模式初探

Research on early-warning models of chlormequat chloride and gibberellins residues in vegetables based on quality control chart

摘要: 以广州市属区(市)市场销售的菜心和苋菜中矮壮素和赤霉素残留数据为基础,基于质量控制图原理和方法,探索质量控制图在蔬菜生长调节剂残留风险预警中的应用。建立了菜心矮壮素残留检出率控制图预警模式以及苋菜赤霉素残留平均值—标准差控制图预警模式,并用假定监测数据模拟了该模式对残留风险的预警作用。

Abstract: Based on the principles and methods of the quality control chart, its application in early warning system of growth regulator residue was detected over the chlormequat chloride and gibberellins residue data of Chinese flowering cabbage and edible amaranth in Guangzhou.The early-warning models for chlormequat chloride residue in Chinese cabbage and gibberellins residue in amaranth were set up, which was respectively based on the “residue detection rate”control chart and the “average residue value-standard deviation”control chart.The two models were proved to be valid for early warning system when applied to assumed monitoring data.
