Abstract

Resistance of stalks to lodging and its weediness should be considered as factors of mechanized production of long flax, which form environmentally friendly preparation and harvesting of Roshen flaxseed. The aim of the study was to study the effect of stem density of long flax before harvesting on its resistance to lodging and weeding, as well as to determine the density of crops in the pre-harvest period, which allows the use of mechanization in harvesting long flax plants and combing stems, their spreading, lifting the flaxseed tape, forming its packaging, loading and transportation. Some of the results of experimental research of a number of scientists on the study of agricultural techniques and measures for the cultivation of flax and the materials of their own research and their generalization were used as initial data. The method of processing the initial data is based on correlation-regression analysis, based on the size of statistical samples used to determine the estimated indicators of qualitative and quantitative relationship of the studied results and factorial features of the processed correlation series and correlation tables. The range of variation of the studied features, the arithmetic mean and the standard deviation and coefficients of variation were determined. The search for the prognostic function was carried out by equalizing the experimental values of the performance traits depending on the factorial rectilinear and a number of curvilinear dependences with the calculation of the corresponding estimates of alignment, errors of regression equations and determination of the coefficient of determination. A negative correlation with the correlation coefficients of minus 0.460 and minus 0.597 was found between the resistance of the flax stalk to lodging and the density of the stalk, taking into account various experimental data, with correlations of the resistance of the stalk to lodging to the density of the stalk, respectively, 0.503 and 0.62, respectively. A negative correlation was also found between the weediness of the stem, the number and density of weeds in it and the density of the stem, with the determination of the corresponding paired estimates of this correlation. The equations of descending hyperbolas of quantitative change of effective signs depending on factorial are found.
