Non-weighing lysimeter capable of measuring water seepage quantity and slope surface water quantity

Abstract

The invention belongs to the field of hydraulic engineering, and particularly relates to a non-weighing lysimeter capable of measuring the water seepage quantity and the slope surface water quantity.The lysimeter specifically comprises a lysimeter barrel; the lysimeter barrel is divided into three parts of an exposed section, a soil column section and a filtering section from top to bottom in sequence; the exposed section completely stretches out of the ground; the height of the soil column section is 60%-75% of the total height of the lysimeter barrel, and is 10 cm or above greater than thedistribution depth of 95% or above of local plant root systems in the soil; the soil column section is filled with local soil; an inner ring is arranged in the filtering section; the interior of the inner ring and the space between the filtering section and the inner ring are both fully filled with fillers; and the bottom of the lysimeter barrel is provided with an inner ring drainage opening andan outer ring drainage opening which are connected with an inner water storage tank and an outer water storage tank correspondingly. According to the non-weighing lysimeter, the runoff amount, the seepage quantity and the seepage time can be simply and accurately measured, and operation is easy and convenient; a quantitative calculation method is provided for assessing the water supply capacity ofan ecosystem; and a new idea is provided for assessing the influence of the change of environmental factors on water source supply of a grassland ecosystem.

AI Technical Summary

Benefits of technology

This patented device measures running-out or filtrate volumes from rainwater collected at different locations along an area's surface during certain times of precipitation. By measuring these quantities over several hours, this technology allows us to accurately determine how much water needs to be supplied compared to what other areas are doing well. Additionally, its design makes it highly resistant against damage caused by external influences like weather conditions that affect crops growing within them. Overall, this device simplifies the process of estimating water resources based on their effectiveness under various environments while also being able to provide precise measurements about changing environmental variables related to crop growth.

Problems solved by technology

This patented technology discusses how understanding the impact of environmental variables like temperature and humidity affects the ability to estimate the water resources supplied by plants across different areas. Current methods are either expensive or require significant amounts of land area, making their use limited due to limitations associated with regulatory requirements.
