Sprayer for multifactorial agrochemical interaction tests

摘要

The invention relates to sprayers for multifactorial agrochemical interaction tests, used to advantage as a fast, correct and energy-saving solution for experiments conducted with chemical fertilizers and agents. The apparatus has interlocking corresponding to the gradient and wave-functions between the runs corresponding to the course and the agent quantities in proportion to the factors, realized preferably by microprocessor control unit setting the feeders (S1-Sn) and choke valves (G1-G4). The settings corresponding to each factor can be separately adjusted and in the process of spraying the machine treats the adjacent plot units by close ratio- and charge realization, as a result of which cultivation tracks are not necessary, the inter-plot penetrations are reduced to minimum and space requirement of the multifactorial experiments is also considerably reduced.
