前言本文提出两份有关改进土壤速效性钾比浊测定法的研究。一份是针对长时期来使用的亚硝酸钻钠比浊法的,另一份则是针对目前正在使用和推广的四苯硼钠比浊法的。因我们在用比浊法测定土壤速效性钾的长期实
Preface This paper presents two studies to improve soil available K turbidimetric assay. One is for long-term use of sodium nitrite turbidimetry method, and the other is for the current use and promotion of tetraphenyl boron turbidimetry. Because we are using turbidimetric method to determine the soil available potassium long-term reality
