摘要

高品質的微生物肥料才能在田間提高植物營養元素的吸收及促進植物生長，而政府的品質管控有助於微生物肥料產品在田間獲得更好及更一致的結果，而且還可以從市場上去除品質差的產品，進而提高農民使用的信心。本文闡述行政院農業委員會農業試驗所於2017年及2018年購買市面上販售溶磷菌肥料產品的檢測結果，包括溶磷菌有效活菌數、雜菌率、溶磷環、溶磷活性及菌種鑑定，其檢測方法參考行政院農業委員會農糧署公告的「肥料檢驗項目之檢驗方法」。由2017年檢測結果可知，農業試驗所由市面上購得的14個溶磷菌肥料產品，僅有5個皆符合農糧署微生物肥料規定，合格率為36%。由2018年檢測結果可知，16個市售溶磷菌肥料產品只有8個皆符合規定，合格率為50%。上述檢測結果，乃國內微生物肥料產品上市以來第一次全面性的品質分析，該分析資料可提供農糧署在微生物肥料產品品質管控及未來微生物肥料法規修改之參考。

Only bio-fertilizers with good quality can assure their promotion in plant nutrients absorption and growth in the field, and the supervision of product quality from government side could play a key role not only in helping bio-fertilizers providing a better and consistent results in the field, but also in eliminating products with bad quality. Both efforts could enhance the farmers’ confidence in these microbial products. In this report, all of the analysis results of commercial phosphate-solubilizing bio-fertilizers, purchased from markets from 2017 to 2018, were documented. The scope of product analysis included total plate count of viable microbes, contamination rate, phosphate-solubilizing halo zone, phosphate-solubilizing activity, and target species identification. All of methodologies followed the publications by Agriculture and Food Agency (AFA). In 2017, only 5 out of 14 commercial products (36%) met the requirements by AFA. In 2018, only 8 out of 16 commercial products (50%) met the requirements by AFA. This is the first product quality report about commercial phosphate-solubilizing bio-fertilizers in Taiwan. This results will be submitted to AFA and be contributed to the revision of the management regulations of bio-fertilizers in the future.
