Description
The negative economic consequences of using sun-flower seeds infested by molds Phomopsis helianthi Munt. Cvet. et al. as inoculums are described in the article. The necessity of finding the ways of these molds inactivation alternative to the way of chemical disinfection, and the advantages of usage of electro-physical ways of seeds’ treatment for this purpose and in particular electromagnetic field (EMF) of microwave frequency (MWF) are explained. The construction of the laboratory experimental setup is shown, on the bases of which the process of Flagman variety of sunflower seeds disinfection EMF MWF is researched. The testing technique is described too. The observable sowing sunflower with the starting infection rate by phomopsis at 22% is treated for different durations in the EMF MWF, being in either static or continuously mowing layers. As result of these experiments the particular rates of treatment providing the total disinfection of sunflower seeds from molds Phomopsis helianthi Munt. Cvet. et al. are revealed and the discovered contradictions in the experiments’ results are explained

Description
In the article, a method of determining of initial ear motion velocity parameters after its separation from the stalk when stripping of grain crops with one-drum header is considered. The dependences of changes of normal and tangential component of ear’s velocity upon the parameters and operation regimes of the header and breadstand characteristics are illustrated

THE HARDWARE SOURCES OF THE AUTOMATION OF THE SOLAR WATER HEATING OF THE AGRICULTURE PLANTS
DescriptionThe article deals with the necessity of the uninterrupted control of the work quality of the solar heating system. The advantages of the microcontroller systems, which gave their evolution in the last years, are shown. The possibilities of the usage of the microcontroller systems for carrying the work quality control are shown. The electrical principal scheme of the system of the automatic control of the solar water heating which allow to control the work quality control are shown. The system was divided into interconnected parts. The methods of the temperature control by the electronic temperature sensors 18B20, water control by the optical pair with open channel and water quantity meter with the optical wheel, water level in the tank by the ultrasonic sensor of the distance and level of the solar radiation by the pyranometer are shown. The necessarily calculation of the geometric tank sizes and water velocity in the solar collector are carried out. The corresponding hardware resources of the PIC microcontrollers like hardware counters, timer with the ability to allow counting by the external signal (Gate Control), analog-digital converter and fixed voltage reference module are described. The algorithms of the control of the water temperature in the tank and the control of the filling the tank with the hot water from the solar collector are described. The methods of the transmitting information to the operator are shown. The advantages of the microcontroller control are described
