Вплив передпосівної обробки насіння льону в магнітному полі на біометричні показники рослин

Abstract

Pre-sowing treatment of flax seeds in a magnetic field increases its yield, reduces plant morbidity, improves their biochemical parameters and product quality. Under the action of the magnetic field, the rate of chemical and biochemical reactions in flax seeds, solubility of salts and acids, biopotential, ion transport, membrane permeability, seed water absorption and oxygen concentration in cells increases, which has a positive effect on plant growth and development. It is established that the change in the biometric parameters of flax during pre-sowing treatment of seeds in a magnetic field depends on the square of the magnetic induction, the gradient of the magnetic field and the velocity of the seeds. Based on the experimentally obtained growth curves of flax plants, it can be concluded that during pre-sowing treatment of seeds in a magnetic field, plants have the best biometric indicators throughout the growing season. The best biometric indicators were in plants whose seeds were treatment in a magnetic field with a magnetic induction of 0.065 T, with four-fold re-magnetization, a magnetic field gradient of 0.57 T / m (pole division of 0.23 m) and a seed velocity of 0.4 m/s. Under this mode of pre-sowing treatment of seeds in a magnetic field, the length of flax stalks increased by 10.5 %, straw yield - by 0.7 t/ ha, seeds - 0.79 t/ ha.
