化肥检验中称样量与检测结果的误差分析

Error Analysis of Sample Weight and Test Results in Chemical Fertilizer Test

化肥检验是粮食安全及农作物高效高产的关键所在,随着中国农业经济的快速发展,使得化肥使用量逐年递增,若化肥质量不达标,势必造成不良影响。因此,提高化肥检验精确度极为重要。鉴于此,文章以化肥样品称样量与检测结果的误差性为切入点,重点梳理了中国化肥行业发展现状及常见化肥检验方法,并以此为动机,提出了消除误差的方法。

Chemical fertilizer test is the key to food security and high yield of crops. With the rapid development of China’s agricultural economy, the amount of chemical fertilizer used is increasing year by year. If the quality of chemical fertilizer is not up to standard, it is bound to cause adverse effects. In view of this, this paper focuses on the analysis of the development status of China’s chemical fertilizer industry and common chemical fertilizer testing methods, and puts forward the method to eliminate the error based on the error between the sample weight and the test results.
