MODULAR MACHINE FOR OIL-BEARING ROSE PRODUCTION

The cultivation of oil-bearing roses requires significant labor and energy resources. The research aims to develop a multifunctional farm implement to mechanize technological operations in rose-growing on small and medium-sized farms. The modular farm implement includes a platform-type base module. Depending on the technological operation performed, it incorporates a spraying system, pneumatic pruning system, side panels, or two workplaces for rose pickers. Using computer simulation with a simulation model created using the "Solid Works" software package, the author determined the profiles and the type of materials for the base module production. Graphoanalytical models help establish the parameters of the other modules of the modular machine. The conducted experimental tests proved the constructive strength of the technical solutions and the functional suitability of the modular machine. It was found that in oil-bearing rose plantations, the farm implement performs spraying at the consumption rates of 300.. .400 l/ha for treatment of the soil surface area under the rose bushes and 1000 l/ha and more for disease and pest control, foliar feeding, and other activities. The variant of the modular machine for selective pruning is ergonomic and efficient at a maximum cut diameter of up to 25 mm and pressure in the tractor pneumatic system between 0.3.. .0.73 MPa. The highest effect of mechanized oil-bearing rose harvesting with the modular machine could be achieved in well-maintained plantations. The optimal height of the bushes should be 1.5.. .1.6 m, and the operation should be performed in the period of active flowering (after 4-5 years of planting or rejuvenation). It is also possible to use the modular machine for transportation purposes. Experimental tests of the developed modular machine for oil-bearing rose production proved the constructive strength of the technical solutions and its functional suitability in several technological operations.
