In mechanized paddy field weeding operations, the rotation of the paddy wheel induces disturbances in the surrounding flow field, which in turn causes significant oscillations of the rice seedling leaves, increasing the risk of seedling damage. Therefore, understanding the impact of hydrodynamics on the mechanical behavior of rice seedlings during mechanized weeding is crucial for improving agricultural efficiency and protecting crops. In this research, the mechanical behavior of rice seedlings during rotation of paddy weeding machinery was studied by combining theoretical model, computational fluid dynamics (CFD) simulation and experimental verification. The research results reveal the nonlinear feedback mechanism between the flow field disturbance caused by mechanical rotation and the seedling displacement. It is shown that under the action of continuous flow field, the deflection of seedlings does not reach steady state at one time, but gradually tends to be stable after fluctuation iteration. Rice seedlings at different growth stages exhibit different behaviors: early seedlings undergo significant deformation under high-speed water flow conditions and have a longer recovery time. In contrast, the seedlings at the late growth stage showed stronger displacement resistance, which was mainly attributed to their higher elastic modulus. In addition, the established model shows good consistency with the experimental results under different flow velocity conditions. This research provides a new theoretical basis for the development of precision agriculture by constructing a complex scene of mechanical weeding in paddy fields with the goal of reducing seedling damage. The findings can further serve as theoretical support and quantitative guidance for the structural design and operational parameter optimization of paddy weeding machinery in precision agriculture.

Wireworms, the subterranean larvae of click beetles (Elateridae), cause substantial economic losses, damaging a wide array of crops and thereby reducing both the quantity and quality of agricultural yield. The efficacy of different countermeasures, notably non-chemical approaches, can vary considerably depending on the species of wireworm encountered and the affected crop system. Surveys of wireworms in damaged crops were conducted in Austria for the first time, with the aim of determining which species most frequently occur as pests. Over a six-year period, a total of 15,786 wireworms were collected directly from damaged crops at 189 agricultural sites across the country. The wireworms were identified, descriptive associations between the occurrence of the species causing damage and abiotic and environmental factors were determined and mapped according to Austrian landscapes. Species-specific occurrence and significance as pests varied across ecoregions and were influenced by the type of crop affected. In the Pannonian region, Agriotes ustulatus (Schaller, 1783) was the most significant pest species in potato cultivation. Its presence was positively correlated with higher st°C, elevated soil pH, and increased clay and silt content. Conversely, in the Bohemian Massif, potato crops were predominantly affected by Hemicrepidius niger (Linnaeus, 1758), for the first time identified as a relevant pest species in Austria. Its occurrence was linked to cooler, more humid conditions, lower soil pH, and higher sand and humus content. These findings provide a basis for future development of region- and species-specific wireworm control strategies, thereby serving as valuable baseline data for distribution and assessment models.
