Ecologically Safe Methods For Presowing Treatment Of Cereal Seeds
UKRAINIAN JOURNAL OF ECOLOGY(2019)
摘要
We analyzed various sources of scientific literature and our data at the experimental field of the National Academy of Agrarian Sciences Plant Growing Institute named after V.Ya. Yuryev within 2010-2013. The irradiation of winter wheat and spring barley seeds with the electromagnetic fields of the extremely high frequencies (MWF of EHF) was carried out with the help of the equipment of the Kharkiv Technical University of Radio Electronics.The treatment of seeds with the microwave oscillations of the extremely high frequency electromagnetic field (MWF of EHF) that is widely used for the operation of many radio and home microwave devices was done at the frequency range of 2.5-3.4 GHz, at the power of 0.9-1.8 kW for 5-95 seconds per 1 kg of seeds. The sowing quality of the seeds before and after treatment was determined in accordance with the current State Standard of Ukraine 4138-2002 in the laboratory of the seed production and seed science of the Plant Growing Institute named after V.Ya. Yuryev. The field experiments were performed in the crop rotation laboratory of the seed production and seed science. Pea for grain was sown before spring barley and the black fallow preceded winter wheat. During the experiments the area of the studied plot was 20 m(2), the recurrence was four-times, and the placement of the plots were systemic. We suggested the optimum regimes of seeds irradiation with the microwave field of an extremely high frequency (MWF of EHF). They should be at range of 2.4-3.4 GHz with the power consumption of 0.9 kW per 1 kg of seed and at exposure of 45 seconds of 1.8 kW per 1 kg of seeds and exposure of 15-20 seconds. Such regimes cause the increased energy of germination, seeds sprouting, and crop capacity. We proposed to use this solution for improving and increasing the ecological features of winter wheat and spring barley by using the presowing microwave irradiation of seeds instead of chemical treatment. We considered the complex presowing treatment of seeds with MWF of EHF in combination with the plant growth regulators should be adopted and further enhanced.
