Katyukha D. Substantiation of technological and design parameters of tools for vegetable intercultivation under drip irrigation.

The object - process and means of an intercultivation of soil in crops of vegetable on the drip irrigation; the purpose - improvement of quality of an intercultivation of soil in crops of vegetable on the drip irrigation by development of a new design of an tools of cultivator and a substantiation of its parameters on the basis of modeling distribution of humidity on width row; methods - the theoretical substantiation of parameters of an tools of cultivator was with use of mathematical simulation, and founded on positions of theoretical mechanics, methods integrated and a differential calculus, a probability theory and mathematical statistics; the novelty - for the first time the dynamic model of change of humidity of soil, depending on distance up to an irrigating tube is developed, for the first time the mathematical model of movement of a weed on an edge curvilinear cultivators pads in conditions of variable humidity of soil is developed; the result - the new design of tool for a soil cultivation in-row vegetable crops on the drop irrigation is developed; the dynamic model of change of humidity of soil depending on removal up to an irrigating tube and external conditions is developed; the model of movement of a weed on an edge cultivators pads is obtained; the area of application - agriculture production
