Description

Technical Field

[0001] The present invention relates to the technical field of simulation test devices, and particularly to a simulation test device for the water seepage capacity of black soil. Background Art

[0002] As a precious resource bestowed by nature on humanity, black soil, with its unique fertile soil texture and rich organic matter content, plays an irreplaceable cornerstone role in many key fields such as global food production and ecological balance maintenance. However, alarmingly, under the intertwined influence of the rapid development of modern agricultural mechanization, frequent high-intensity agricultural reclamation activities, and climate change, black soil is facing an unprecedented soil degradation crisis. Among them, the dynamic changes in soil water seepage performance have a far-reaching impact on the healthy growth of crops and the effectiveness of regional soil and water conservation. In view of this, accurately and efficiently understanding the degree of change in the water seepage and water holding capacity of black soil after being compacted has become a key issue that urgently needs to be solved in the field of black soil protection and sustainable utilization, and a dedicated water seepage simulation test device has become an indispensable "weapon".

[0003] However, there are still some deficiencies in the current design of soil water seepage capacity simulation tests: First of all, on the one hand, in the conventional process of conducting soil water seepage and water holding capacity tests, it is necessary for staff to use professional tools to take stratified samples of soil at different depths. This process is not only cumbersome and time-consuming, but also extremely prone to introducing errors due to improper human operation. More seriously, during the sampling process, the original hierarchical structure order of the soil sample will inevitably be disturbed, resulting in a deviation between the subsequent test data and the soil performance in the actual natural state, and it is impossible to truly reflect the inherent characteristics of the soil. Secondly, most current simulation test devices have congenital limitations in their design architectures and can only detect the water seepage and water holding capacities of soil under flat ground conditions. However, the actual black soil landforms are complex and diverse, with a large number of sloped terrains, such as gentle slopes in hilly areas and slopes at the edges of gullies. Since existing devices cannot simulate the water seepage and water holding conditions of soil on such sloped terrains, the obtained simulation test results are too one-sided, and the derived data is difficult to comprehensively cover the true performance of black soil under various terrain conditions, greatly limiting the all-round and in-depth understanding and research of black soil by scientific researchers, and thus hindering the accurate formulation and effective implementation of black soil protection strategies.
