TECHNICAL AND TECHNOLOGICAL PARAMETERS OF THE PROTECTION ZONE PROCESSINGIN PERENNIAL PLANTATIONS

Abstract

Maintaining modern intensive plantations requires the latest practical and theoretical knowledge, the application of which achieves top-quality production results. In recent years, more and more attention has been paid to both energy efficiency and environmental aspects as the ultimate goal of the sustainability of each production. The sustainability of a process can limit reaching the maximum of said process. In the technologies of soil maintenance in perennial plantations in recent years, it becomes imperative that the chemical treatment of the soil, immediately adjacent to the plant and within the row, be replaced by mechanical processing. This need is primarily aimed at minimizing the use of pesticides in order to respond to the environmental requirements. Regular land cultivation is a technically complex problem. The given area is made up of up to 25% of the total land area of the plantation. The paper presents the results of testing a rotary harrows with a deflection, which in one pass achieves the processing of a part of the inter-row surface and half of the protective zone. The results of the research show that the optimal speed of movement of the aggregate carried out in the plantation of the orchard is 1,56 m/s, and in the plantation of the vineyard 1,23 m/s. Productivity of aggregates in the orchard 0,24 ha/h, in the vineyard 0,19 ha/h. Fuel consumption in the vineyard 7,2 l/ha, and in the orchard 6,8 l/ha. Productivity of the aggregate is largely conditioned by the technical solution of the aggregate and the technology of plantation cultivation.
