Energy dose of flax seed treatment in a magnetic field

Abstract

Pre-sowing treatment of flax seeds in a magnetic field makes it possible to improve seed sowing performance and increase flax yield without the use of mineral fertilizers and chemical plant protection products. Compared to other electrophysical methods, pre-sowing seed treatment in a magnetic field is a highly productive, low-energy, safe method for service personnel and the environment. It is now established that the yield and biometric indicators of crops depend on the dose of magnetic treatment. Therefore, the aim of the study was to determine the optimal energy dose of flax seed treatment in a magnetic field. An analytical expression for determining the energy dose of flax seed treatment in a magnetic field is obtained, which contains all the mode parameters of seed treatment. It is established that the energy dose of flax seed treatment in a magnetic field depends in direct proportion to the square of magnetic induction and polar division and inversely proportional to the velocity of seed movement in a magnetic field. The conducted multifactorial experiment made it possible to determine the germination energy and germination of flax seeds at different energy doses of treatment. This made it possible to determine the optimal mode of flax seeds treatment in a magnetic field. It is established that the optimal mode of pre-sowing treatment of flax seeds in a magnetic field is magnetic induction 0.065 T, four-fold re-magnetization, pole division 0.23 m, seed velocity 0.4 m/s, providing an energy treatment dose of 1.79 J · s/kg. With the optimal treatment of flax seeds in a magnetic field, germination energy increased by 30 %, germination - by 2 6%, stem length - by 10.5 %, straw yield - by 0.7 t/ha, seeds - 0.79 t ha.
