One of the promising directions of increasing productivity in forestry production is a systematic approach to specifying the process efficiency of the wheeled forwarder based on constructing a single technological connectivity of all performed operations from the initial “loading” to the final “start of unloading”. System analysis allows to form coherent and flexible technological processes as single space-time production structures. The process efficiency of such structures depends on the extent to which the basis of the system analysis is used in assessing the fleet of forestry equipment or its elements. The basis of the unified connectivity of the discrete operations (the movement of the forest machine along the skidding track from pack to pack, setting the crane to the operating position, moving the grip towards the log, grabbing the log on the ground, sorting the log, aligning the pack, moving the pack into the cargo compartment, placing the log into the cargo compartment, installation of the crane into the transport position, and movement along the skidding track) from the position of the system theory is a representation of the functional time of manufacturing a production unit (1 m3 of wood) by operation and its superposition for all production operations. The superposition builds a single functional time for the integrity of the operations performed, in which the target function of the production structure is efficiently implemented. An analytical study of determining the effective performance in the functional time of the production process of the wheeled forwarder is given from the position of the system analysis. The article examines the timing of the work of the Ponsse Buffalo wheeled forwarder in the most typical natural and industrial conditions of the rental base of the Mondi Syktyvkar JSC (middle taiga of the Komi Republic). The method of calculating the total capacity of the wheeled forwarder as a result of performance of all operations (loading, storage, and transportation to the place of unloading) is proposed. The possibility of applying the proposed method of assessing the wheeled forwarder efficiency is shown in terms of implementation of forecasting the total productivity of the forest machine in the functional time of manufacturing a production unit. The method allows you to choose the directions of increasing the labor productivity by synchronizing the functional time of all production operations.

Combine Harvesters

Аnnotation Purpose. To increase the efficiency of technological processes of grain harvesting by large-scale agricultural producers due to the rational use of combine harvesters available on the farm. Methods. In the course of the research the methods of system analysis and synthesis, induction and deduction, system-factor and system-event approaches, graphic method were used. Results. Characteristic events that occur during the harvesting of grain crops, both within a single production unit and the entire agricultural producer are identified. A method for predicting time intervals of use and downtime of combine harvesters of production units has been developed. The roadmap of substantiation the rational seasonal scenario of the use of grain harvesters of large-scale agricultural producers is developed, which allows estimating the efficiency of each of the scenarios of multivariate placement of grain harvesters on fields taking into account influence of natural production and agrometeorological factors on the efficiency of technological cultures. Conclusions 1. Known scientific and methodological approaches to optimization of machine used in agriculture do not take into account the risks of losses of crops due to late harvesting, as well as seasonal natural and agrometeorological conditions of each production unit of the farmer, which requires a new approach to the rational use of rational seasonal combines of large agricultural producers. 2. The developed new approach to the substantiation of the rational seasonal scenario of the use of combined harvesters of large-scale agricultural producers allows taking into account the costs of harvesting of grain and the cost of the lost crop because of the lateness of harvesting at optimum variants of attraction of additional free combine harvesters. provides more profit. 3. The practical application of the developed road map will allow large-scale agricultural producers to use combine harvesters more efficiently and reduce harvesting costs.

Abstract The Siberian silkworm (Dendrolimus sibiricus Tschetv.) is a defoliator pest that poses a significant threat to coniferous forest stands. Over the past decades, several large outbreaks of this species have occurred in Siberia (Russia), which has led to changes in forest ecosystems and an increase of expenses involved in reforestation. Adults capture new territories in the process of migration, therefore, a set of measures is needed to register the number and prevent further dispersal of the moth. One of methods of trapping is glue traps with synthetic pheromone. 16 district forestries located in the middle taiga subzone, with a total area of 151 850 hectares, were surveyed as a part of the phytosanitary monitoring of the Siberian silkworm in the Komi Republic (Russia). Analysis of 773 pheromone traps showed 414 males of the target species that were identified by their genitals. The highest indicators of catchability were found in three district forestries. Taking into account the results obtained, it was proposed to continue the monitoring using the pheromone traps, to survey more northern forest districts and to carry out subsequent searches for preimaginal stages of the silkworm in the forest districts of Priluzsky district. The study will be useful for predicting the further spread of the silkworm and for developing optimal containment and control of the pest.

In this paper, we analyze applicability of Land degradation neutrality (LDN) concept of the UN Convention to Combat Desertification for Russian boreal forests. In this regard, it is necessary to adapt the three global LDN indicators (land cover, land productivity, and carbon stocks) to the assessment of land degradation processes of boreal forests in Russia and around the world. The proposed study concludes that landscapes with different types of forest restoration dynamics can be viewed as the object in forest land dynamic studies. The proposed research also suggests the set of LDN indicators adapted for boreal forests conditions. In order to assess LDN proxies we calculated the retrospective and projected net carbon balance in the middle taiga zone of Noshulskoye forest domain (Komi Republic, Russia) using the CBM CFS model. Here we explored 3 scenarios of forest net carbon balance under the three different felling regimes. It was shown that the net carbon balance cannot be applied as an independent LDN indicator, since it does not take into account changes in species diversity and primary productivity. We also suggest that industrial felling should imitate natural types of restoration dynamics in order to achieve LDN targets. It can be reached through minimization of forest felling at sites with fireless types of succession, which accumulate maximum stocks of dead phytomass matter and serve as forest refuges supporting biodiversity.

The paper presents the results of the research on the growth, development, and biochemical evaluation of introduced Pyrethrum majus plants in the middle taiga subzone of the Komi Republic. It is established that in the conditions of culture the species is characterized by a high stability and winter hardiness. The phenology and dynamics of plant growth were studied. Morphological parameters of vegetative and generative shoots were determined. The yield of essential oil from the aboveground phytomass of P. majus and its component composition were studied. It was found that the content of essential oil of flowering plants varied over the years of research from 0,25 to 1,41% and depended on the weather conditions of the growing season. More than 190 components were found in the essential oil of P. majus plants using the method of GLC analysis, 48 of them were identified. The main terpenoids in the essential oil were S-(+) carvone (5465%), -tuyon (610%), TRANS-and CIS-p-Menta-2,8-dienols (2,32,8%), 1,8-Cineol (1,42,9%), CIS Menta-1(7)8-Dien-2ol (1,52,1%), germacrene d (1,21,8%) -cadinol (0,51,5%), -muurolol (0,22,6%). It was found that the component composition of the essential oil from perennial plants P. majus corresponds to the carvone-Tuyon chemotype and did not change significantly due to the meteorological conditions of the environment. Taking into account a high adaptation of plants of this species to the conditions of the middle taiga subzone of the Komi Republic, high indicators of aboveground phytomass with a sufficient content of essential oil, P. majus can be successfully cultivated in the North as a promising spicy-aromatic medicinal and ornamental plant.
