水解性氮又称土壤有效性氮,它包括无机态氮和部分有机物中易分解的比较简单的有机态氮,如氨基酸、酰胺和易水解的蛋白质。据试验资料记载,一般每生产50公斤小麦,就要从土壤中吸收1.5公斤氮素,如果我们能及时准确地测定土壤水解氮的含量,通过合理施肥保证作物正常的氮素代谢,就能达到增产的目的。但迄今为止测定土壤水解 Hydrolyzable nitrogen, also known as soil available nitrogen, includes inorganic nitrides and some simple organic nitrides, such as amino acids, amides and easily hydrolyzable proteins, which are easily decomposed in some organic substances. According to the experimental data, generally, for every 50 kg of wheat produced, 1.5 kg of nitrogen must be absorbed from the soil. If we can determine the content of soil hydrolyzed nitrogen in time and accurately and ensure the normal nitrogen metabolism of the crop through reasonable fertilization, The purpose of increasing production. However, so far soil hydrolysis has been determined
