Abstract

The invention relates to the technical field of detection, in particular to a detecting method of the nitrogen content of a cotton plant. The detecting method comprises the following steps: step one,sampling: taking fresh cotton plant leaves; step two, preparation of a grinding device: preparing the grinding device; step three, sample treatment: processing the sample obtained in step one by adopting the grinding device, and forming a smashed sample; step four, digestion: adding the smashed sample obtained in step three in concentrated sulfuric acid, and uniformly mixing; then heating the mixed solution, and heating until the solution is a uniform brownish black color after generating white smoke; stopping heating, and cooling; adding hydrogen peroxide after cooling, heating until boiling,and digesting for 6 to 12 minutes; cooling again, and adding hydrogen peroxide; digesting until the solution is colorless or clear, and heating for 10 to 12 minutes again; finally taking and coolingsample liquid; step five, filtering by adopting filter paper or standing and clarifying the sample liquid cooled in the step four, taking clear liquid, and determining the nitrogen content. Accordingto the scheme disclosed by the invention, the problem that decomposition and extraction of plant leaves in the prior art are incomplete is solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method for detecting the nitrogen content of cotton plants. Background technique [0002] Fertilization is one of the main technical measures to increase cotton production. However, with the continuous improvement of people's pursuit of economic benefits in cotton planting, the amount of fertilization has a tendency to increase. Cotton plants absorb the nutrients in the fertilizer to make the cotton plants grow better, so the absorption of nutrients by cotton plants is an important factor in determining the growth of cotton plants. [0003] Among them, nitrogen is the main component of protein, which plays a very important role in the growth and development of stems and leaves; The absorption of fertilizer nutrients, and then obtain soil and fertilizers that are beneficial to plant growth. [0004] For the determination of nitrogen content, an automatic azotometer is usuall...
