The current primary methods for detecting MSG and IMP are expensive and complex, limiting their widespread applications. Hence, there is a need to explore novel and more affordable methods to characterize umami taste substances. FT-IR was used to detect umami substances, MSG, and its mixture with IMP. Uniform spectral spacing method (USS) was combined separately with a continuous projection algorithm (SPA), competitive adaptive weighting algorithm (CARS), and uninformed variable elimination method (UVE) to simplify partial least squares regression (PLSR) and principal component regression (PCR) prediction models. The results demonstrated that the optimal model for MSG solution detection was the USS-CARS-PCR quantitative simplified model based on 17 feature wavelengths with =0.97, =0.23 g/L, =0.96, and =0.27 g/L. For MSG and IMP mixture detection, the optimal model was the full wavelength model with =0.97, =0.11 g/L, =0.98, and =0.07 g/L. These findings indicate the feasibility of using FT-IR spectroscopy for rapid and quantitative detection of umami substances, providing a theoretical basis for detecting complex umami substances in food using FT-IR technology.

Therefore, six common edible polysaccharides were selected in this study to investigate their effects on the rheological properties, thermal properties, and microstructure of acid-induced soybean isolate protein self-assembled gels (SPIASG). The experimental results showed that the support capacity and creep recovery of SPIASG with added polysaccharides were higher than those of the control group without added polysaccharides, and the gel with Xanthan gum (XG) was the most effective. The hybrid gel, with added Condensed resin (CR), Xanthan gum (XG), Carrageenan (CA), and CMC formed a stronger network structure. Additionally, compared with SPIASG, the hybrid gel with added edible polysaccharides the water-holding capacity of SPI hybrid gels was relatively improved. In this study, a simple and easy method was obtained to significantly improve the gel properties of SPIASG, analyzed and compared the effectiveness of various polysaccharides to enhance its gel properties, and provided some ideas to improve the gel properties of SPI protein gels.

It was found from the study results that the addition of 50% neem crude oil emulsifiable concentrate (neem oil), isomeric alcohol ethoxylates and BYK-405 all significantly decreased distribution span (S) and the percentage of droplet size less than 150 μm (ΦVol<150μ) values, but significantly promoted the median volume (D50) value. And the surface tension measurement results showed that all tested adjuvants significantly reduced the surface tension, while neem oil, FC4430 and silwetl-77 were observed with a most significant effects; Furthermore, all tested adjuvants except BYK-051N could also significantly decrease the contact angle, and the difference between neem oil, FC4430 and silwetl-77 was significant. Wind tunnel test results clearly demonstrated that the application of IDKA (a combination of air-induction nozzle IDK120-01 and neem oil) substantially decreased the drift deposition amount; In addition, the field experiments revealed that IDKA possessed a significantly improved deposition amount per unit area on canopy or bottom, leading to a more effective deposition. These results suggest that the use of IDK120-01 nozzle and neem oil can effectively reduce spray drift, lessen surface tension and enhance spreading.

To simplify the management of nutrient solution pH and attenuate negative effects of pH on plant growth, this study investigated the effect of different buffer salt additions on nutrient solution pH, ion uptake, growth and photosynthesis of Yamazaki lettuce, with the equivalent concentrations of macro-element unchanged. The results indicated that the pH of nutrient solution was buffered to varying degrees by the 2 mol/L HCO_3^-, 1 mol/L HCO_3^-, and 0.33 mol/L HPO_4^(2-) treatments. The 0.33 mol/L HPO_4^(2-) treatment fluctuated most with a pH of 1.74 units, while the addition of HCO_3^- buffered nutrient solution pH was better, with higher pH values (7.2-7.7). The CK-pH control solution, 1 mol/L HCO_3^- and 0.33 mol/L HPO_4^(2-) treatments all promoted the uptake of ion and then the growth of lettuce was better in comparison with the CK-pH no adjustment treatment, while the 2 mol/L HCO_3^- treatment inhibited K uptake and reduced the availability of Fe, the shoot and root fresh weight of lettuce decreased by 21.3% and 10.1%, respectively. In addition, although the chlorophyll content and net photosynthetic rate under 1 mol/L HCO_3^- and 0.33 mol/L HPO_4^(2-) treatments were significantly lower than the CK-pH control solution treatment, there were no significant differences in leaf length and leaf number of lettuce among them, and shoot fresh weight per plant was 83.09, 82.95, and 78.92 g, respectively. In conclusion, adding 1 mol/L HCO_3^- to the nutrient solution in a single dosage not only buffered the pH of nutrient solution better but also promoted ion uptake, it had no negative effects on the growth, photosynthesis and ion uptake of hydroponic lettuce in comparison with the CK-pH control solution treatment. Therefore, 1 mol/L HCO_3^- can be used as a buffer during the growth of hydroponic lettuce and reduce frequent addition of acids or alkalis, and then simplify the management of nutrient solution for hydroponic lettuce production.

For energy-saving and life-extension, the tillage resistance and wear-corrosion of subsoilers have attracted wide attention. In this study, the tillage resistance, soil disturbance, wear and corrosion of subsoiler with S-T-SK-2# biomimetic structures (S means subsoiler; T means tine; SK means shank; 2#, h/s=0.57, h=5 mm and α=45°.) and self-healing coating under two seasons, two locations with different soil properties (black loam and clay soil) and subsoiling speeds (2 km/h and 3.6 km/h) were investigated. The soil moisture content and compactness affected the tillage resistance and wear-corrosion. The tillage resistance and degree of corrosion on all subsoilers were much larger in clay soil than that in black loam soil. Compared with S-T-SK-2#, the tillage reduction rate of C-S-T-SK-2# (S-T-SK-2# with self-healing coating) was up to 14.32% in clay soil under the speed of 2 km/h. The significance tests of regression equation results showed that subsoiler type and soil properties had a significant impact on soil disturbance coefficient, swelling of total soil layer, bulkiness of the plough pan. It is of a guiding significance for the analysis of soil disturbance. Synergism mechanism of subsoiler coupling with biomimetic structures and self-healing coating was analyzed in following. It depicted the guiding effect of biomimetic structure and the shield function of self-healing coating, resulting in anticorrosion and wear resistance of subsoiler.

In this paper, a planting unit for rice dry-direct-seeding planter is designed. The working principles and structural parameters of the furrow opening components, the seeding apparatus and the soil covering-pressing device are described. The mechanical model of the key components of the seeding unit was established, and the forward speed, roller diameter and compacting strength were selected as the test factors. A three-factor, five-level quadratic rotation orthogonal combination test was conducted with the seed breakage rate, seeding depth qualification rate, seeding uniformity coefficient of variation and hole grain count qualification rate as the evaluation indexes. Field performance test and test results show that: at a forward speed of 4 km/h, a roller diameter of 427 mm and a compacting strength of 48.45 kPa, the seed breakage rate was 1.31%, the sowing depth qualification rate was 9.95%, the coefficient of variation of sowing uniformity was 3.75% and the number of holes was 86.75%.

The autonomous agricultural machine has shown revolutionary effects on labor reduction and utilization rate in field works. Autonomous vehicles in precision agriculture have the potential to improve competitiveness compared to current crop production methods and have become a research hotspot. However, the development time and resources required in experiments have limited the research in this area. Simulation tools in unmanned farming that are required to enable more efficient, reliable, and safe autonomy are increasingly demanding. Inspired by the recent development of an open-source virtual simulation platform, this study proposed an autoware-based simulator to evaluate the performance of agricultural machine guidance based on digital twins. Oblique photogrammetry using drones is used to construct three-dimensional maps of fields at the same scale as reality. A communication format suitable for agricultural machines was developed for data input and output, along with an inter-node communication methodology. The conversion, publishing, and maintenance of multiple coordinate systems were completed based on ROS (Robot Operating System). Coverage path planning was performed using hybrid curves based on Bézier curves, and it was tested in both a simulation environment and actual fields with the aid of Pure Pursuit algorithms and PID controllers.

Most of the existing self-propelled tillers rely on manual adjustment of the tillage depth. Moreover, the consistency and stability of the tillage depth are difficult to guarantee. In this study, the automatic control method of tillage depth of a self-propelled electric tiller is investigated. A method of applying the fuzzy PID (Proportional Integral Derivative) control method to the tillage depth adjustment system of a tiller is also proposed to realize automatic control. The system uses the real-time detection of the resistance sensor and angle sensor. The controller runs the electronically controlled hydraulic system to adjust the force and position comprehensively. The fuzzy control algorithm is used in the operation error control to realize the double-parameter control of the tillage depth. The simulation and experimental verification of the system are conducted. Results show that the control system applying fuzzy PID can improve the soil breaking rate by 3% in the operation process based on reducing the stability variation of tillage depth by 24%. The control strategy can reach the set value of tillage depth quickly and accurately. It can also meet the requirement of tillage depth consistency during the operation.
