Description
Technical field
This utility model embodiment is related to environmental monitoring technology field, and in particular to a kind of underground eluviation in-situ sampling cartridge
Put.
Background technology
With the development of the intensive agricultural of high investment high production, impact of the widespread pollution from the overuse of fertilizers and pesticides in rural area to environment becomes increasingly conspicuous,
Widespread pollution from the overuse of fertilizers and pesticides in rural area problem becomes impact soil and water pollution, threatens agricultural product quality and safety and hinder agricultural sustainable
The matter of utmost importance of development.Agricultural management due to lacking science, in agricultural production, chemical fertilizer, pesticide and water resource usage amount are high
And utilization rate is low, soil resource is lost in and seriously polluted, causes agricultural resource to waste and degenerates serious.Therefore, agricultural area source is dirty
Dye process study is efficient utilization agricultural resource, administers agricultural environment pollution, improves agricultural production conditions and ensure agricultural production quality
The most important thing of amount safety.
Subrosion is that pollution of area source, soil erosion, nutrient loss, pollutant and nutrient such as migrate at the process in soil
Occasioner and main carriers.Research shows that the about 30-50% Jing soil leaching losses of the fertilizer in being manured into soil enter subsoil water, opposite
State environment threatens.Therefore, widespread pollution from the overuse of fertilizers and pesticides in rural area subrosion research is Soil nutrient loss ways, Ides On Prevention And Control of Regional Pollution
Important foundation.
At present, mainly there are potter's clay suction agar diffusion method, percolating filter method, leaching to the research method of soil subrosion Transport
Disk method, localized collection etc..Potter's clay suction agar diffusion method and leaching disk method can only gather the soil liquid of certain point, it is impossible to measure leaching
Amount；Continuous filter method is arranged using concrete, and quantities is big, and high cost is obvious to soil disturbance.
Although existing underground eluviation in-situ collection device is widely applied in terms of subrosion monitoring, also deposit
Substantially not enough：(1) filter layer is easily blocked up on bung, causes to collect the situation less than leaching liquor；(2) long-term field operating process
In, the continuous pull liquid suction pipe of meeting causes liquid suction pipe in bottom of the barrel is collected water can not be caused to collect leaching liquor when few,
And liquid suction pipe easily departs from collecting vessel by pull, monitoring failure is caused；(3) liquid suction pipe is exposed in earth's surface, affects farming operation, causes
Liquid suction pipe adjacent ground surface cannot be sowed, apply fertilizer, and affect monitoring result, and exposed liquid suction pipe to be easily damaged and steal and abandon, and cause prison
Dendrometry loses.
