自全国腐植酸类肥料试验推广经验交流会议之后,一个波澜壮阔大搞腐植酸类肥料的群众运动已在全国蓬勃兴起。各地在生产和使用腐肥过程中,需要简便、快速、准确的分析方法。为此,我们在原燃化部《腐植酸类肥料的原料及产品分析方法介绍》基础上(以下简称方法介绍),对容量法的氧化条件作了某些验证和比较试验。现将试验小
Since the humic acid fertilizer test was conducted in China to promote the exchange of experiences and experiences, a mass movement of humic acid-type fertilizers has sprouted across the country. Around in the production and use of fertilizer process, the need for simple, rapid and accurate analysis. For this reason, we made some verification and comparative experiments on the oxidation conditions of the volumetric method based on the introduction of the method for the analysis of raw materials and products of humic acid-based fertilizers in the former Ministry of Combustion (hereinafter referred to as the method). Now the experiment is small
