FIELD: agriculture.
SUBSTANCE: method involves measuring signal of melioration drainage channel depth, setting melioration drainage channel depth signal, comparison of measured and preset signals and control of depth of melioration drainage channel comparison results, generating signal of depth of melioration drainage channel, periodical scanning range of variation of melioration drainage channel depth signal from minimum to maximum tolerable value of that signal, generating signal of dependence cost of power consumption for fuel and electric power for drying of selected area from melioration drainage channel depth signal. At first number of land given section for drying or for complex reclamation signal is set, depending on that signal coefficients of mathematical models of dependences values environmental losses of signal depth melioration drainage channel at drying and in complex reclamation are set, coefficients of mathematical models of dependences values of crop losses from signal depth melioration drainage channel at drying and in complex melioration, predicted value of average annual air temperature at specified section and predicted value of average annual power density of solar radiation on ground surface at specified section. Dependences values environmental losses, dependencies of cost of crop losses from signal depth melioration drainage channel at drying and in complex melioration at specified section signals are generated. Setting signals of depreciation, repair and for renovation of two types of equipment for drying and for complex melioration at specified section. Preset signals of depreciation, repair and for renovation of two types of equipment for drying and for complex melioration at specified section are summed up with appropriate formed signals dependences values of power consumption for fuel and electric power for drying of the selected area, with appropriate formed signals dependences values environmental losses and with appropriate formed signals relationships values of crop losses from signal depth melioration drainage channel at drying and in complex melioration at specified section. By results of summation total signals of depreciation, repair and for renovation, dependences values of energy costs of dependences values environmental losses, dependences values of crop losses from signal depth melioration drainage channel at drying and in complex melioration at specified section are formed. At least value of total summed signals new corresponding to minimum values of said sums values costs signals economically optimal depth melioration drainage channel at drying and in complex melioration at specified section are generated. Measured signals of melioration drainage channel depth at drying and in complex melioration at specified section are compared with appropriate formed new signals of economically optimal melioration drainage channel depth at drying and in complex melioration at specified section. By comparison results of measured and relevant formed new signals additionally corrected melioration depth adjustment mode of drainage channel at drying and in complex melioration at specified section. Device comprises meter of melioration drainage channel depth 1 signal, melioration drainage channel 2 depth controller, melioration drainage channel 3 depth controller actuator, melioration drainage channel 4 depth signal generator, unit of periodical scanning (deflection) range of variation of melioration drainage channel depth signal from minimum to maximum tolerable value of that signal 5, signal of values dependences of power consumption during drying and in complex melioration 6, computing unit 7, control unit 8. Device includes signal generator of number of given section for drying or for complex reclamation (setter of section geographical location in climatic and soil zone) 9, setter of coefficients of mathematical models of dependences values environmental losses of melioration drainage channel depth signal at drying and in complex melioration 10, setter of coefficients of mathematical models of dependences values of crop losses from melioration drainage channel depth signal at drying and in complex melioration 11, setter of predicted value of annual average air temperature at specified section 12, setter of predicted value of average annual insolation at given section (average annual power density of solar radiation on ground surface at specified section) 13, signal shaper of dependences values environmental losses, dependencies of cost of crop losses from melioration drainage channel depth signal at drying and in complex melioration 14 signal generator of depreciation, repair and for renovation of two types of equipment for drying and for complex melioration 15 two-input controlled switch 16, selection signal generator for direction of drying or complex melioration 17. Use of invention defines automatically determined optimal mode of drainage amelioration.
EFFECT: higher accuracy of consumption of expensive energy sources for mechanized equipment, higher considerable additional saving environmental losses of natural territory and economic crop losses on selected plot territory soil-climatic zones country, decreased manual labour costs at performance of measurements, calculations and control of personnel machines for land reclamation, increases productivity of grazing at section of land reclamation.
