An experimental device for soil acidification soil improvement

Abstract

The invention discloses an experimental device used for soil acidification soil improvement. In the invention, mass experiments can be realized so as to carry out orthogonal research on the parametersof different modifier additive amounts. A helical tooth embossment is arranged at a position opposite to a stirring component on the inner wall of an experiment pot, and one side of the helical toothembossment, which is far away from the inner wall of the experiment pot, is provided with a tapered inclined surface so that a stirring effect can be improved and the uniformity of an experiment in the experiment pot is ensured. The upper end of the internal portion of the experiment pot is provided with a spray seat. The lower end surface of the spray seat is a spray hole. The side surface of the spray seat is provided with a plurality of mist inlet branch holes. The side surface of the experiment pot is provided with a mist inlet main hole. The spray pipe of a spray generator is inserted into the mist inlet main hole so that the spray pipe is connected to the mist inlet main hole. The control of soil moisture can be increased through a spray mode; and through arranging a PH sensor, PH value detection can be performed on soil in a barrel in real time and the real-time monitoring of a soil acidity change is realized.

Description

technical field [0001] The invention relates to the technical field of soil acidification, in particular to an experimental device for improving soil acidification soil. Background technique [0002] Soil acidification refers to the process in which the soil absorptive complex accepts a certain amount of exchangeable hydrogen ions or aluminum ions, so that the alkaline (basic) ions in the soil are leached. Lime can be applied to adjust acidity and calcium supplementation. Acidification is the soil Weathering is an important aspect of the process of soil formation, resulting in a decrease in pH value, the formation of acidic soil, affecting the activity of organisms in the soil, changing the form of nutrients in the soil, reducing the availability of nutrients, and promoting the dissolution of free manganese and aluminum ions into the soil solution. Toxic to crops. [0003] However, the experimental devices for acidified soil improvement currently on the market not only have...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of experimental device for soil acidification soil improvement, to solve the problem that not only the function is single, but also the practicability is poor. Usually, the work of uncapping is performed manually, and there is no stirring assembly. It cannot realize the mixed work of acidified soil and alkaline improved fertilizer, which reduces the improvement effect of acidified soil. At the same time, it does not have a pH sensor, and cannot detect the acidity change of acidified soil in real time, which brings inconvenience to its experimental work.
