“…Bai et al investigate the biological effects of a 4 kV/m electrostatic field on barley seeds and 4.5 kV/m sugar beets for 10 minutes. Their results showed that electrostatic fields of a certain intensity can increase the amount of free radicals in seeds [9]. Rotcharoen et al studied the effect of electric field on rice growth and found that electric field strengths of 193 kV/m and 4 kV/m had a significant effect on the growth rate and height of rice plants [10].…”

Currently, Uzbekistan is among the twenty most advanced countries in the cultivation of onions. The onion plant was interpreted as a symbol of life in ancient Greek mythologies. Onion is one of the most widely consumed foods in the world due to its essential health and preventive properties, as one of the most essential fruits in the kitchen in the daily diet. The article studies the methods of processing onions before planting based on an analysis of the countries of the world. The results of studies of the influence of various electrophysical parameters on onion seeds are presented analytically. The effective influence of the electric field strength on the health of seeds is explained. The authors also referred to the results and methods of scientific research conducted at NRU “TIIAME” and analyzed the electrical and mechanical properties of onion seeds based on specific experiments. In particular, we analyzed the mass of 1000 seeds, the filling factor of the cubic container, and the initial (primary) results of determining the electrical and thermal conductivity of soaked seeds. The article also provides information on the impact of alternating electric current on onion seeds, developed special electrodes for determining electrical resistance, and a methodology for conducting research experiments. An electrical circuit is presented that ensures the completeness of seed treatment. There are also materials on the positive effect of “electrically activated” water on the additional health of soaked onion seeds. It is shown that the necessary conditions have been created for the process of automated intelligent control of the temperature of soaked onion seeds.

“…A triangle tracked chassis for a sugarcane harvester was designed by Bai Yuanqiang. The adaptability of a triangle track and flat track combination to slope ground was better than that of a traditional track sugarcane harvester [12]. A four triangular tracked camellia fruit picking machine with good adaptability to southern gentle slope land was developed by Cai Gangchu [13].…”

The middle and lower reaches of the Yangtze River are the main production area of rapeseed. Small windrowers with two tracks are adopted in this area, which have lower efficiency. With the advancement of large-scale rape planting, medium and large windrowers are urgently needed; however, most medium and large windrowers are wheeled machines which have poor adaptability to sticky soil in rice–rape rotation areas. Therefore, a wheel-track high clearance chassis for rape windrower was developed. Theoretical analysis and simulation of the main performance of this chassis were investigated. Mathematical models of the relationship between the chassis eccentricity and running resistance, uphill and downhill angle and the height of obstacle were established. Then, three-dimensional modeling and dynamic simulations of a wheel-track high clearance chassis of a rape windrower in wet clay soil were carried out based on Pro/E and RecurDyn software. The simulation results indicated that when the chassis ran on flat hard road at the same speed, eccentricity had little effect on average walking speed; the coefficient variation of speed decreased with the increase of eccentricity, while the driving torque and its coefficient variation decreased first and then increased. The minimum driving torque and the coefficient variations were obtained when the eccentricities were 1484 mm and 1584 mm. Field experiments were carried out on two kinds of ground. The results showed that on flat hard road, the speed of the wheel-track high clearance rape windrower was 0~20.22 km/h, the minimum turning radius was 5.965 m; on rice stubble field with 38.7% water content, the working speed was 0~9.12 km/h, the minimum turning radius was 6.498 m, and the climbing angle was over 20°. All parameters of the wheel-track high clearance chassis met the design specifications, and the working efficiency increased over 100% compared with the existing two-tracked rape windrower. A new kind of rape windrower for the middle and lower reaches of the Yangtze River was provided.

“…For the finger chain type, Mou et al carried out simulation analysis and bench test research on the problems of missing support and lift lodging angle parameters [19]. At present, sugarcane harvesters on the market mostly still employ the installation of spiral crop dividers, and interested scholars have carried out a series of studies into this [20]. In [18,20], the effects of different lodging angles, forward velocity (FV), scrolls speed and the ground clearance of the crop divider toes on lifting performance were investigated in a field experiment.…”

et al. 2022

As a critical component of the sugarcane harvester, the primary function of the crop dividers is to lift the lodged sugarcane (LS) and reduce the loss rate of the sugarcane harvest. In this study, a rigid-flexible coupling simulation method is proposed to improve the lifting efficiency of the crop dividers on severely LS and analyze the nature of interaction between the sugarcane stalk and the crop dividers. The model’s accuracy was verified using field experiments, and the operational performance of the crop dividers on sugarcane in different lodging postures was investigated. The results showed that the curve of the vertical height of the center (VHC) fluctuated more and slipped with highest frequency during the lifting process of side and forward LS. The speed of VHC was fastest during the lifting operation of side LS. The effect of side angle on the lifting effect of sugarcane was significant; the qualified values of the VHC of sugarcane being lifted in different lodged postures were: side and reverse lodged > side lodged > side and forward lodged. The coupling method and experimental results described in this paper can provide guidance for the optimal design and field operation of the crop dividers.
