Elaborating of the device for the importation of liquid ameliorants into the soil

[摘要] Ameliorants (materials which have very high ionic capacity and hold moisture) are applied for long-term improvement of soil's features in production of crops. A device is elaborated for liquid ameliorants' importation into the subsoil space which allows increasing uniformity of an importation and quality of their dispersion in the space under a flat hoe at sweep soil cultivation. This tool contains supply pipe-line with the distributive openings which are evenly located on its length, a material stream divider, the channel of supply of material and the air duct with openings. We have conducted preliminary laboratory researches in which two types of springs were applied: with the equidistant coils and with the decreasing step-by-step distance of coils to an extreme last opening. In the second case the identical rate of flow from openings was observed because the pressure was supported on all length of the pipeline. Thus, as a result of the theoretical analysis and laboratory experiments we established dependence of design data's change of the coil on the created pressure on width of the developed device for the local importation of liquid ameliorants into the soil at sweep soil cultivation.
