| titleOfInvention | A new method for the determination of soil nitrate reductase activity |
| abstract | The invention belongs to the technical field of soil nitrogen cycle determination, and discloses a new method for the determination of soil nitrate reductase activity. Using potassium nitrate (KNO 3 ) as a substrate, soil is subjected to constant temperature and anaerobic conditions of 30° C. for 24 hours ( h) reduction culture, by measuring the soil nitrate nitrogen (NO 3 - -N) content before and after reduction and calculating the difference to obtain the amount of reduced NO 3 - -N per gram (g) of dry soil to be reduced The amount of NO3 -- N characterizes the nitrate reductase activity of the soil. In the culture experiment in the present invention, the decompression conical flask is replaced by a common conical flask and a vacuum container, and the phenolic disulfonic acid colorimetric method is used to measure the NO 3 - N content by a continuous flow analyzer, which is similar to the previous method. It can significantly reduce the experimental error and improve the accuracy of the measurement results and the test efficiency. |
