FORECASTING OF OUTPUT AND NUMBERS: SCUTCHED FLAX ACCORDING TO THE RESULTS OF LABORATORY PROCESSING OF FLAX STRAW
It is known that for annual forecasting of flax plant operation on output and number of long and short flax fibers, data obtained from processing flax into scuttled flax is often used on SMT-200M or SMT-500 laboratory machines, and not on pulping machines, which can lead to overestimation performance flax plant. The yield of long fiber, flax numbers and scutched flax obtained on the machine CMT-500 and in the knead-scutch unit ALS-1, characterized by handful feeding, were studied. Samples of flax straw from nine breeding varieties of the harvest in 2018, with a normal degree of curing, strong fiber, moisture, equal to 12% were used. It was found that the fiber after the machine SMT-500, in comparison with the meat-breaking machine ALS-1, differs in quantity, more by 3.11% (abs.), And in quality, higher by 1-3 numbers. According to the obtained number of long fiber, using the standards of production, the number of trusts is predicted. It turned out to be lower than the experimental figures for 2-4 numbers. It is determined that the approximate correction factor for predicting the output of scutched flax is 0.89. Processing of the experimental data using univariate analysis of variance showed that the effect of the processing methods under study is 24.0% for the yield of long fiber and 39.0% for the number of scutched flax with a confidence level of 0.95. A method for determining the overestimate of flax number when processing it using the SMT-500 machine is presented. Recommendations are given for predicting the yield and the number of scutched flax in ALS-1 according to the results of quality assessment of flax on the machine CMT-500.
