The present invention relates to agriculture and can be used during the cultivation of crops to reduce the negative impacts of droughts.

The essence of the problem to be solved is that in conditions of the South of Russia are often observed winds - South or South-East winds that carry dry and hot air. Due to the low humidity of the wind has a dampening effect on plants even when adequate soil moisture, as the root system does not have time to compensate for the loss of moisture in the leaves of plants.

A known method of regulating the humidity of surface air, including wetting of the leaf surface of plants during the hottest time of the day with the installation of spray irrigation mounted on tractors. The spray lasts for two hours (Patent RF №2172583, MKI A01G 25/09, BI No. 24, 2001).

The disadvantage of this method is the necessity of creation of irrigation systems, high energy intensity of the process associated with repeated daily passage facilities spray irrigation on the field at intervals of not more than two hours.

Known stationary irrigation system regulating the temperature and humidity of air, consisting of a water distribution network is supplied to the nozzles melodiers the CSOs sprinkling. Such stationary irrigation system provides round-the-clock control of humidity surface air at the site (Patent RF №2322047, MKI A01G 25/02, BI No. 11,2008,).

The disadvantages of this system are: the need for the construction of irrigation network, its high energy consumption and cost.

Famous windproof and snow retention system of shelterbelts to regulate the microclimate of the field, which is placed on its borders (Handbook on reclamation, M., Rosagropromizdat, 1989, S. 313-316).

Shelterbelts promote the accumulation of winter precipitation falling as snow, and stockpiling of soil moisture when it melts in spring. In summer during the dry winds trees and shrubs reduce the speed and temperature of the wind, raise the humidity of the air, vaporizing the water from the leaf surface and thus reducing the negative impact of droughts on agricultural crops cultivated in the area of the belts. This system is adopted as a prototype.

The disadvantages of this system of regulation of microclimate fields are the duration of the growing process of the belts until the plant height, providing effective protection from the winds; the high cost of works on creation of shelterbelts associated with the need for irrigation of seedlings in the first years after planting and care Les what apolosi; the need for periodic planting of new plants to replace those killed, as well as spending the most part stored in the retention of moisture on water use by the vegetation of the forest.

To eliminate the mentioned disadvantages allows the proposed system of regulation of microclimate fields comprising placed along the field boundary wind and snow retention elements, characterized in that it includes a reservoir arranged along a field boundary from the most likely penetration of winds, on the opposite sides of which are placed along the field vertical blinds height of not less than half the width of the reservoir, installed with the possibility of rotation around the vertical axis and tilt in a vertical plane.

In addition, the bottom of the reservoir may be covered with impervious material, along the pond can be set to spray water, and as sources of energy for the spray water system can be equipped with one or several wind power plants and solar panels.

A new technical result is that placed on the field boundary from the most likely penetration of winds reservoir, fitted blinds, allows winter snow retention on the surface of a pond with water accumulation in the spring posleduuschei protecting it from evaporation before the start of the winds, and you are experiencing the winds to produce a slower rate and temperature, to increase the humidity by installing blinds on both banks of the reservoir at a selected angle to the wind direction. The use of sprays of water will ensure a more efficient humidification up to 5 - 6 m, and drive them from wind turbines and solar panels will save the cost of energy for electricity generation.

The essence of the proposed technical solution is illustrated by drawings, where figure 1 shows a General view of the system of regulation of the microclimate of the field with the position of the elements shutters on field # 1 at operation snow guard and the No. 2 - mode humidification when the winds; figure 2 - system with the position of the blinds while maintaining the accumulated moisture; figure 3 - cut system And when the sprays of water.

Regulation of microclimate field is located mainly along the southern boundary of the field 1 of the reservoir 2, on the North and South banks of which the axis 3 is set plate louvers 4, while in the lower part of axis 3 are mounted hinges 5, which enable the plates blinds can be rotated around a vertical axis and tilt in a vertical plane. Along the longitudinal axis of the reservoir 2 can be laid pipe 6 with melkodispersnye and nozzles 7, mounted on the uprights 8. The water supply pipe 6 is connected to the pump 9 driven by electricity generated by a wind power installation and solar panel 10. The bottom of the reservoir 2 may have an impervious floor 11. When the device of the reservoir, the width of which can be 4-6 m at a depth of 2-4 m, the extracted soil distribute adjacent to the reservoir site, forming the bias field surface side of the reservoir 2.

The proposed system of regulation of microclimate field works as follows.

With the onset of winter installs plates blinds 9 on the mode of the snow guard. Because the overwhelming amount of snow bring the Western and North-Western winds, blinds 4, located on the Northern shore of the reservoir 2, installed in accordance with the direction of the wind, and blinds on the South shore of the reservoir 2 at an angle thereto (Fig 1 field # 1). The height of the blinds is 2,5-3,0 m Meeting with a barrier, reduces wind speed, thus there is a loss of some snow. When you hit the air flow between the lines blinds is changing its direction, and accordingly, the additional speed reduction and the precipitation of part of the snow. Thus it is filled with snow reservoir 2 and the formation of snow over it and the surrounding areas.

Spring is : size is out of pond 2 water as due to accumulated snow, and runoff from adjacent areas. Impervious layer 11 prevents seepage water losses. After the filling of reservoirs produce protection of water from evaporation by creating shelter. This plate blinds have 4 parallel to the reservoir 2, producing a rotation axis 3 in the hinges 5 and placing the plate louvers 4 above the surface of the pond. In this case, since the height of the blinds 4 less than half the width of the reservoir 2, the ends of the blinds obrazovat roof, which will protect the water in the reservoir from evaporation. However, this roof will not impede the flow in the reservoir sediments.

Upon the occurrence of droughts axis 3 is transferred in the vertical position, the plate louvers 4 on the South side of the reservoir turn in the direction of the winds, and on its North side at an angle to the wind direction (figure 1 field # 2). Wall formed blinds, creates an obstacle in the path of the winds, reducing its speed. The Northern line blinds changes the direction of air flow, causing turbulence, which increases evaporation from the surface of a pond.

After installing blinds for a better effect can be included fine spray of water 7, to which water is supplied through the water supply pipe 6 from the pump 9. Design fine spray allows you to throw to a height of 5-6 m size drops 50-100 MK, about rasua over the pond cloud of spray 12. These droplets completely evaporate, increasing the humidity. When the evaporation of water not only increases humidity, but also decreases its temperature and increases the density, so the cooled and humidified air will fall to the earth's surface, creating a more favourable microclimate in the surface layer, where there are plants. The water spray in the air continue until the termination of the winds and recovery are favorable for plant moisture of the surface layer of air.

To provide electrical power to the pump and fine spray appropriate to use renewable clean energy sources - wind energy plant with solar panels 10. The feasibility of using both sources is dictated by the need to ensure the smooth operation of the system, as during the dry wind power wind during the day may vary and be reduced to quantities not sufficient to operate a wind power installation and solar panels do not work at night.

Thus, the proposed system is the protection of adjacent fields from the destructive action of the winds, which have a significant effect on its microclimate, reducing the rate and temperature of the winds and increasing humidity of the surface layer is ozdoba due to moisture, accumulated during the winter. In addition, the use of natural, environmentally friendly sources of energy - wind and solar, can reduce operating costs.

SUBSTANCE: invention is intended for metrological determination of the internal quantum efficiency of a semiconductor photodiode based on the current-voltage characteristic thereof. The oxide biasing method is the known method of calibrating photodiodes. The efficiency of collecting charges for photocurrent generated in a p+ region needs to be determined in order to describe silicon p+nn+photodiodes. The primary reason for losses in the frontal region is the high rate of electron-hole recombination. This effect is intensified by the presence of positively charged ions which result in a surface electric field. The oxide biasing method is widely used to determine the extent of this effect on the internal quantum efficiency of a diode. The advantage of this method is direct measurement of saturation photocurrent and calculating internal quantum efficiency therefrom. However, this method has a shortcoming which lies in the degradation of the working surface of the semiconductor under the effect of a high negative voltage applied to the surface. The aim of this invention is to provide a method of determining quantum efficiency of a photodiode, which is based on comparing experimentally measured current-voltage characteristics thereof with theoretically calculated characteristics. This aim is achieved by recording to current-voltage characteristics of a photodiode at two different power values of incident laser radiation for which only the ratio is known. Said characteristics are then compared using a developed calculation procedure.

EFFECT: simple calibration procedure while maintaining accuracy characteristics of the photodiode.
