IRRADIATOR INSTALLATIONS FOR CULTI-VATING CONSTRUCTIONS
DescriptionThe article deals with the issue of alternating irradiator installation for growing plants in protected soil. The point of the method of illuminative installation con-sists in periodical influence of relatively high irradiance upon plants against a background of constant influence of relatively low one. It reduces plant radia-tion irregularity, improves the quality of agricultural products and cuts down energy-output ratio of growing processes.

DescriptionThe process of the presowing seed treatment with alternating electromagnet field of the commercial frequency (EMF CF) 50 Hz is economically efficient. The use of the EMF CF 50 Hz in the unit with ring pole pieces allows increasing the germinating energy and power. The electromagnet seed treatment in the units with ring pole pieces is the perspective process of the presowing treatment which does not make unhealthy influence on the operating personnel. At the presowing treatment one has to take into account three factors; they are the arrangement of seeds in the working chamber, the time of treatment and the seed humidity. In this article the authors recommend to promote the unit consisting of a magnetic circuit with ring pole pieces of the rectangular cross-section, a magnetizing coil and an embedding of the nonmagnetic material in the working chamber which allows to increase the germinating energy of spring barley by 10% and the germination by 6,5%. The addition to crop capacity has run to 7% as a result of the spring barley treatment. We analyzed the parameters of the working chamber of the alternating electromagnetic field source of industrial frequency of 50 Hz, we established the dependence of the rate of treatment on the parameters and modes of installation, which are confirmed by laboratory tests. Long-term field studies revealed that the field germination rate of the seeds of spring barley treated with EMF IF, even under adverse weather conditions, exceeds by more than 8% of the field germination rate of control samples

Description
The article is devoted to the development of a compressor type ozonator. It describes the design of a high-productivity compressor ozone generator, which can be used for industrial decontamination of mixed feeds, water, milk, and in the system of presowing treatment of seeds. This construction allows generating ozone with high concentration to 5 g/m3 at high feed air or oxygen from the compressor station (up to 2000 l/min). The article describes the design of the basic elements of tubular ozone generator, examines the factors influencing the productivity of the ozonator. The proposed mathematical model allows calculating the productivity of the ozonator when considering multiple influencing factors. These factors take into account: the parameters of supply voltage, such as the magnitude and frequency of the supply voltage; the configuration and geometrical parameters of electrodes such as, the area of the electrodes, the configuration of the surface of the electrodes and distance between electrodes; parameters dielectric barrier; and the transported gas parameters such as volume, temperature, pressure and composition. Special attention is paid to the design of the electrodes made of woven wire mesh with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted, that such electrodes allow obtaining the maximum productivity of an ozonator, and they do not lead to overheating of the dielectric barrier, and do not output down the generator. In the same way, the article presents the results of the mathematical modeling of ozone generator productivity while changing various factors
