Description

technical field [0001] The invention belongs to the technical field of cultivation equipment for soil hydrolysis nitrogen experiments, and in particular relates to a cultivation device and a cultivation method for hydrolysis nitrogen experiments. Background technique [0002] Soil hydrolyzed nitrogen includes inorganic nitrogen and relatively simple organic nitrogen decomposed in some organic matter. Soil hydrolyzed nitrogen is the sum of ammonium nitrogen, nitrate nitrogen, amino acids, amides, and easily hydrolyzed proteins, which can reflect the soil's short-term Nitrogen supply, also known as soil available nitrogen. As an index, the determination of soil hydrolyzed nitrogen is widely used in the laboratory, and this index has certain practical significance for understanding the nitrogen supply of soil, and is often an important index to guide rational fertilization.

Problems solved by technology

[0003] The traditional culture equipment for hydrolysis nitrogen cultivation mainly includes a blast drying oven and various incubators for cultivation. However, the traditional cultivation equipment is only a temporary cultivation equipment built to meet the needs, not a special one for hydrolysis nitrogen. The cultivation equipment of the experiment cannot understand the cultivation status of the soil samples in each incubator at the same time; in addition, in the test method of the hydrolysis nitrogen experiment, it is required to shake 3 times during the cultivation period, which is artificially shaken, which is very labor-intensive and very expensive. Difficult to operate, low work efficiency, and easy to cause pollution. It takes a long time to cultivate. Generally, it needs to be cultivated for 24 hours. Especially in terms of time, it needs to be shaken at night, and the experimenters need to work overtime to shake, which greatly increases the labor of the experimenters. Work intensity
