氨基酸是土壤中一类重要的化合物,占土壤全氮含量的15%–60%,在土壤氮素循环和植物养分供给过程中扮演着重要的“库”与“源”角色。氨基酸既可通过矿化作用满足作物对氮素的需求,也可被植物直接吸收利用。此外,氨基酸还是土壤微生物的重要氮源,对微生物群落结构、数量及活性均有直接影响。因此,研究土壤中氨基酸含量的变化规律,对于揭示土壤氮素循环及其对植物生理生态的影响具有重要意义。本产品提供了一种简便、快捷的土壤氨基酸含量检测方法。检测原理为:氨基酸的α-氨基与水合茚三酮反应生成蓝紫色化合物,该产物在570 nm处具有特征吸收峰,通过测定570 nm吸光度即可计算氨基酸含量。
Amino acids are an important class of compounds in soil, accounting for 15%–60% of the total soil nitrogen content. They play a crucial role as both "sources" and "sinks" in soil nitrogen cycling and plant nutrient supply. Amino acids can satisfy crop nitrogen requirements through mineralization, and can also be directly taken up by plants. Furthermore, amino acids serve as an important nitrogen source for soil microorganisms, directly influencing microbial community structure, abundance, and activity. Therefore, studying the dynamics of amino acid content in soil is of great significance for understanding soil nitrogen cycling and its effects on plant physiological ecology. This product provides a simple and rapid method for determining amino acid content in soil. The assay principle is based on the reaction of the α‑amino groups of amino acids with ninhydrin hydrate to form a blue‑purple compound. This product exhibits a characteristic absorption peak at 570 nm, and the amino acid content can be calculated by measuring the absorbance at 570 nm.
