<p>The invention relates to sprayer 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 and choke valves. 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 miminum and space requirement of the multifactorial experiments is also considerably reduced. A special advantage of the apparatus is the mechanization and more accurate interpretation of the multifactorion experiments, it facilitates the increased and more efficient use of the aerial survey techniques, but it can be used to advantage in confined space or under greenhouse etc. conditions as well. Since there are no cultivation tracks, the crops - depending on the spraying variations - can be more easily harvested by machine, than those so far, and the plots ensure the same continuous cultivation surface as the large-scale cultivation. The apparatus is suitable for the easy and fast realization even of 5 - 10 factorial multi-repetitive experiments, thus it allows the experimental optimization of nearly all parameters of the modern complex technologies in a single process.</p> |
