Optimization of technical parameters of the complex for climate control beehives allowed to choose the optimal ratio of the technical parameters of the equipment in accordance with the optimization objective. Evaluation of the efficiency of the self-contained complex is considered in two aspects: in relation to conversion and transmission of energy and in relation to the specific consumption of material resources. In this regard, was chosen two criteria characterizing the efficiency of the complex - the energy efficiency and material capacity. In article presents a methodology to optimize constructive parameters of the energy supply system based on the combined solar plant. The resulting optimal ratio of the parameters are the basis for the engineer's decision that design complex for climate control beehives.

The article is devoted to the problem of improving the efficiency of removal of trees and shrubs (cutting and milling) in a continuous movement of forest machines. Brush cutters with active and passive working elements, as well as specialized machines are used for cutting and milling trees and shrubs. These machines have a disadvantage. It is a low reliability in operation. A general layout scheme of machines for removal of trees and shrubs is offered in the article which allows minimizing this problem. The machine has two working bodies: a basic and an additional. The basic working body is for cutting trees and shrubs. The additional working body is for milling stumps and roots and also for mixing pieces of wood with soil.

Nanotechnology is a technological breakthrough in agriculture, have great potential because they allow you to combine economic efficiency and natural ingredients to solve many problems in agriculture. To achieve high efficiency in agricultural production in recent years, using new agrobionanotehnologies. Authors of this article is working on the development of environmentally safe (nano) technology treatment of seeds of different crops using multi multifunctional biologically active (nano) chips. The obtained test results allow us to conclude about the prospect of being developed (nano) technology pre-sowing treatment and training opportunities 1-2 applications for patents on new research conducted in the development of the developed concept of «non-pesticidal agricultural products.
