Background

Nitrogen is one of the important nutrients which can be provided to plants by soil, wherein the soil alkaline hydrolysis nitrogen is also called quick-acting nitrogen and can be absorbed and utilized by crops recently. The content of alkaline hydrolysis nitrogen can reflect the nitrogen supply capacity of soil in the near term, is an important index for judging the effectiveness of soil nitrogen elements, mainly comprises inorganic nitrogen and organic nitrogen which is easy to decompose in partial organic substances, and is the sum of ammonia nitrogen, nitrate nitrogen, amino acid, amide, protein nitrogen and other substances. The content of alkaline hydrolysis nitrogen in soil is not stable enough, and is easy to change under the influence of soil hydrothermal conditions and biological activities, and mainly depends on the content of organic substances in soil, the quality and quantity of nitrogen fertilizers and the like.

At present, the soil alkaline hydrolysis nitrogen content is generally measured domestically by an alkaline hydrolysis diffusion method, wherein the alkaline hydrolysis diffusion method firstly adopts alkali liquor to treat soil, ammonium nitrogen which is easy to hydrolyze and organic nitrogen are converted into ammonia, then the ammonia is effectively absorbed by boric acid solution, and finally, standard acid is used for titration to calculate the alkaline hydrolysis nitrogen content. The diffusion ware is main household utensils utensil among the alkaline hydrolysis diffusion method measurement process, and traditional diffusion ware is mostly glass diffusion ware, because outer room formula structure as an organic whole in the glass diffusion ware for following problem appears easily in the testing process:

1. because the diffusion vessel needs to be opened and closed and rotated for many times in the measuring process, the alkaline glue solution for sealing the diffusion vessel easily pollutes the solution in the inner chamber, thereby influencing the working efficiency to a great extent and increasing the operation difficulty at the same time.

2. Because the glass diffusion vessel moves frequently in the operation and later-stage washing processes, the glass diffusion vessel is easy to break or loose in sealing due to collision, the accuracy of a test result is influenced, and the detection cost is indirectly increased.
