EXPERIMENTAL RESEARCH OF THE PROCESS OF SELECTING FLAX STEM ROLLS

Abstract

The research is devoted to the problem of implementing a separate technology for harvesting flax with low stem cutting, grown in the conditions of the Western Polissia. The obtained results are based on our own field studies of the cultivation of Liryna and Entant flax varieties and Miander and Oberig flax varieties on chernozem and sod-podzolic soils. The peculiarities of the formation of the organic flax harvest under the influence of natural and climatic conditions are described, the need for the application of a separate harvesting technology with a low stem cut of both types of flax in conditions of global warming is proven. Schemes of the developed equipment for conducting experimental studies of modeling the behavior of stems under the action of working bodies during the selection of rolls inserted by cutting with a stem rotary mower are presented. The peculiarities of conducting studies on determining the parameters of the rolls in the process of maturing the boxes and transforming the stems into a trust are indicated, taking into account their placement in the rolls under the action of the cutting apparatus of the rotary mower. The results of research on determining the deflection and bending of the stems in the windrow, establishing the destructive force that can lead to the loss of the integrity of the windrows, taking into account their size, the content of weeds, the condition of the boxes and the conditions for capturing the stems, are presented. The obtained results are necessary both for the improvement of the rotary mower and for the development of a pick-up of flax rolls with stems placed in the longitudinal plane for the application of a separate harvesting technology of flax with low stem cutting, grown in favorable conditions for the formation of a high yield of seeds and fibrous stem mass. Continuation of this research in the following years will allow to propose the improvement of high-performance technical support, taking into account the technology of harvesting flax and the formed harvest of seeds or fiber under the influence of climatic conditions of the current season.
