t has now been established that under the influence of a magnetic field, the rate of chemical and biochemical reactions that occur in cells increases solubility of salts and acids, as well as the permeability of membranes, which accelerates diffusion through the membrane of molecules and ions. It contributes to the stimulation of seeds, growth and development of plants.
The application of technology of pre-sowing seed treatment in a magnetic field necessitates the establishment of a mechanism for its influence on seeds and determination of the most efficient treatment mode.
The purpose of the research is to determine the influence of the magnetic field on the water absorption of wheat seeds.
Under the action of a magnetic field, diffusion of water molecules increases, resulting in increased water absorption of seeds.
Experimental studies were carried out with seeds of wheat of the "Natalka" variety. Seeds were transported on a conveyor through a magnetic field created by four pairs of permanent magnets from the NdFeB intermetallic composite, mounted in parallel above and below the conveyor belt with variable polarity.
Magnetic induction was controlled by changing the distance between the magnets in the range 0-0.5 T and measured with a 43205/1 Telesameter. The speed of the seed movement through the magnetic field is regulated within 0.4 - 0.8 m/s by changing the frequency of rotation of the drive motor of the conveyor with the help of a converter of current frequency.
Controlled and seeded in a magnetic field was weighed to soak and after soaking in distilled water for 30 minutes and determined the specific water absorption.
Investigation of the influence of magnetic induction and velocity on the absorption of wheat seeds by magnetic processing was carried out using the theory of experiment planning.
It has been experimentally established that for changes in magnetic induction from 0 to 0,065 T, the water absorption of barley seeds increases, and with further increase in magnetic induction begins to decrease. It was established that under the magnetic induction, which exceeds 0.130 T, water absorption varies insignificantly and makes up 11.5 % for wheat (8.3 % for control).
The maximum water absorption of wheat seeds was 0.065 T after magnetic induction. The effect of magnetic processing depends on the speed of the seed, but in the range of speeds of 0.4-0.8 m / s it is a less significant factor than the magnetic induction. The best results were obtained at a speed of 0.4 m/s.
On the basis of the conducted researches it was established that the water absorption of wheat seeds by magnetic processing depends on the square of the magnetic induction and the speed of the seed movement in the magnetic field. The most effective treatment mode takes place after the magnetic induction of 0.065 T and the seed speed of 0.4 m/s. Under this treatment, water absorption of wheat seeds increased by 6% compared to control.
y regulator was tested.
