Description
In the article, we have motivated the definition of the problem of increasing of efficiency of oil production with complicated conditions. We have also considered general system problems of increasing of the efficiency of oil production with the methods of the improvement and renovations of the equipment: the equipment for optimization of the factor of the extraction of oil; oil well rod pumping units and principles of energy saving on the late stage of the production of the bore holes with complicated condition of exploitation. It is shown, that the equipment allows optimizing the factor of the extraction of oil when developing hard extraction oil stocks, combined with modern technology and methods

AGROCLIMATIC FACTORS OF FORMATION OF A CROP OF LONG-TERM CULTURES
06.00.00 Agricultural sciences
DescriptionIn the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established
