To increase productivity in agricultural production, combined wide-grip machines are being created, aggregated with tractors of traction classes from 5 and higher. In addition, according to agrotechnical requirements, the pressure of the mover on the soil should be minimal, as well as the number of passes over the surface of the field. These contradictions can be solved by ballasting of tractors, which allows using engine power to increase tractive effort. Ballasting affects energy saturation. Increased energy saturation with appropriate ballasting makes it possible to compose machine-tractor units (MTU) according to a more accurate ratio of the tractor pulling force and the unit's pulling resistance. The most in demand in modern agriculture are tractors of 5-6 traction classes produced by domestic and foreign tractor-building plants with an internal combustion engine with a capacity of 220-320 kW and an operating weight of 115-150 kN. The article contains a two-way analysis of variance, which makes it possible to determine the greatest influence on the ballasting of a tractor. A diagram is constructed that gives an idea of which of the studied brands of tractors can be recommended for performing agricultural operations, taking into account ballasting and compliance with agrotechnical requirements. Keywords: TRACTOR, BALLASTING, ENERGY SATURATION, TWO-FACTOR ANALYSIS OF VARIANCE

Agricultural mechanization has become the main mode of agricultural production and represents the development direction of modern agriculture. The amount of data generated in the agricultural production process is extremely huge, so it is necessary to introduce the concept and analysis method of big data. Combining agricultural robots with big data can improve the performance and application effect of robots. This paper combines big data, WLAN technology and robot technology to realize man-machine remote cooperation platform. This gives full play to the advantages that people are good at object recognition and robots are good at execution, and improves the fruit picking efficiency. The target fruit positioning and recognition system aided by machine vision is adopted to realize the accurate positioning of the fruit to be picked. Design of LFM control signal fitting based on big data clustering. In order to verify the feasibility of the scheme, taking the tomato picking robot as an example, the communication error and control accuracy using big data and WIFI (Wireless Fidelity) technology were tested, and the positioning and navigation efficiency with and without remote monitoring system was compared. Test results show that using big data and WIFI remote monitoring technology can effectively improve the efficiency and accuracy of positioning and navigation of remote operating system, which is of great significance for the design of automatic control system of picking robot.

Modern highly mechanized agricultural production is characterized by the incompatibility of simultaneous matching of the maximum pressure of agricultural mobile equipment movers on the soil and the possibility of increasing the tractors energy saturation when equipping them with existing wheel engines.(Research purpose) To coordinate the maximum pressure on the soil with the permissible norms, weight utilization factors and the level of tractors energy saturation.(Materials and methods) The authors used a calculated method for determining the maximum pressure on the soil using a universal tire characteristic.(Results and discussion) The authors found that when performing spring works on closing moisture and sowing row crops at a maximum pressure of 80 kilopascals, corresponding to all types of soil, the most mass universal row tractor Belarus 1020 had a maximum pressure of 150 kilopascals, which was 70 kilopascals higher than the permissible one for the corresponding crop shortage. They found that replacing ordinary tires with agrophilic tires could increase the area of the contact spot by 16 percent, while reducing the coefficient of unevenness and increasing the coefficient of use of the adhesion weight. The main condition for replacing ordinary tires with agrophilic tires was to keep the traction force unchanged.(Conclusions) Summarizing the results of the research as agrophilic direction, ensuring the compliance impacts on soil and positively solving the problems of saturation, it is possible to recommend the development of navigation systems in achieving utilization hitch weight equal to 0.5 (low tire pressure), equal to 0.6 (rubber joint with torsion bar suspension) and 0.7 (rubber track). It was found that the conducted research, taking into account the available data on traction tests of the T-250 tractor, would allow to include an agrophilic concept with a hypothetical dependence of the adhesion weight use factor on the longitudinal unevenness coefficient in the revised State Standard 27021-86 “Agricultural and forestry Tractors. Traction classes”.

This paper involves the modern agricultural application control system which is based on internet of things, and this intelligent management system uses intelligent control technology such as S7-300, GSM,WSN and Zigbee to realize the modernization of rural security, agricultural production and residents living fully intelligent managed. This system applies precision agriculture, digital image processing, wireless data transmission and other fields, really combining digital management technology with embedded technology. At the same time, this system which is based on internet of things is the necessary path of modern agriculture informatization strategy. With the mature development of technology of internet of things in modern society, modern agriculture application management system based on internet of things will bring new change to agriculture and high efficiency of agricultural production.

Moore’s law relates how the integration of semiconductors has progressed in time. This research shows that the exponential trend shown in the electronics manufacturing industry can have applications elsewhere. This study shows that the internal combustion engine followed the same trend for over 70 years. Though not the most used engine variable, engine power density shows the same trends for engines as transistor density does for microchips. This now mature technology has ended its period of rapid growth. However the present day engine trends can show how Moore’s law can be extended to include the slower growth of long established technologies. Because exponential growth cannot go on forever, the extension Moore’s law requires that the logistic function be used. The new function also allows one to predict a theoretical value for maximum power density.

Urban agricultural landscape depends on agricultural production, which is a composite function of the system with the combination of modern agriculture, rural culture, tourism and leisure as well as environmental education, farming experience. With the development of rural and urban, urbanization and agricultural modernization, metropolitan agricultural landscape has been given serious impact and challenge. The article analyzes relationship between rural, urban development and metropolitan agricultural landscape, then, it proposed strategy of the metropolitan agricultural landscape in Taihu Lake.

The technical demands of games can be affected by changing the number of players, pitch size and rules. This controlled trial compared the frequency of technical skills between a ‘traditional’ and newly introduced systematically ‘modified’ game of primary rugby league. A total of 475 primary rugby league players (Under 7s to 9s) were filmed playing traditional ( n = 49) and modified ( n = 249) formats. Notational analysis examined the frequency of technical skills (e.g. number of passes) within ‘traditional’ and ‘modified’ games. At each age category, multivariate analysis of variance indicated the clear superiority of the ‘modified’ game for the frequency of technical skills (e.g. Under 7s total skill opportunities – ‘traditional’ = 342.9 ± 47.0; ‘modified’ = 449.4 ± 93.3, d = 1.44, p < 0.001). Systematically modifying the competitive game is an effective way to increase skill opportunities for children within rugby league. Future research should examine the outcomes of modifying games in optimizing skill development in youth sport.
