Abstract

The invention discloses a plough layer soil percolating water collecting device, which comprises a round pipe the bottom end of which is closed. The round pipe is divided into an overground part and an underground part. The upper part of the underground part of the round pipe is provided with a plurality of percolating water collecting holes at the periphery and the top end of the round pipe is provided with a pipe cover. Compared with the prior art, as water collecting disc, the percolating water collecting device made through the technical scheme has the following characteristics: (1) the invention occupies little area, has simple installation and does not damage the original structure of soil, (2) the invention has strong pertinence for collecting the soil plough percolating water, (3) the collection and sampling of the invention dose not consume energy sources, which is favorable to field long-term positioning test, and (4) the invention has convenient collection and sampling and the collected percolating water has low turbidity and can be measured and determined easily.

Description

A kind of plough layer soil percolating water collecting device
Technical field
The present invention relates to a kind of leakage water collecting device, be specially a kind of plough layer soil percolating water collecting device, belong to the agricultural environmental protection sciemtifec and technical sphere.
Background technology
In recent years, use the widespread pollution from the overuse of fertilizers and pesticides in rural area that causes in a large number owing to fertilizer and pesticide, agricultural production and soil environment caused had a strong impact on, and agricultural land soil percolating water is that the higher plough layer soil percolating water of important carrier, especially nutrient content that pollutant runs off in the widespread pollution from the overuse of fertilizers and pesticides in rural area is one of main path of pollutant loss.
At present, the method that adopts lab simulation leaching or land for growing field crops water-collecting tray to collect is usually studied soil percolation water.The lab simulation leaching adopts the test method of column simulation more, this method comparative maturity and simple, but the test unit that the collection of field soil percolating water is unfixing, mostly be to place a water-collecting tray in the underground a certain degree of depth, put sand in the dish, the water of water-collecting tray flows into the header tank that a physical features is ploughed, and the water that regularly takes out header tank is the soil percolation water under certain area of regular period.The percolating water that this test method obtains is comparatively muddy, store as untimely, composition in the water is easy to change, the physical features of header tank is lower than water-collecting tray in addition, then be unfavorable for long-term location observation test as landfill not, then need electricity consumption or take as landfill, floor area is big, very inconvenience of field in the open air.Above method all is to collect at the percolating water of soil different depth, does not conduct a research especially topmost arable layer in the agricultural land soil at a certain soil layer.Therefore, seek a kind of device that more is applicable to agricultural land soil arable layer leakage water collecting, just can better carry out open-air long-term location observation test.
Summary of the invention
The objective of the invention is for a kind of plough layer soil percolating water collecting device is provided, to solve the problems referred to above of prior art.
Purpose of the present invention can be achieved through the following technical solutions.
A kind of plough layer soil percolating water collecting device comprises the pipe that the bottom is sealed, and described pipe is divided into aerial part and under ground portion; Around the tube wall of the under ground portion top of pipe, be provided with some leakage water collectings hole; The top of pipe is provided with the pipe lid.
Described round tube inside diameter is 8cm, and length is 2.2m.
Described pipe is the PVC pipe.
Described under ground portion buried depth is 2m, and aerial part is 0.2m.
Described collection hole is in the under ground portion of the pipe position of 25cm to 55cm overhead.
Described collection hole diameter is 8mm, and pitch of holes is 10mm.
The peripheral wrapping of described collection hole has the plastics gauze.
Relate to the leakage water collecting device that forms by technical solution of the present invention and compare, have following characteristics with prior aries such as water-collecting trays:
(1) floor area of the present invention is little, and simple installation can accomplish not destroy the soil prototype structure;
(2) the present invention collects plough horizon percolating water, and is with strong points;
(3) collecting and sampling of the present invention does not need consumes energy, helps open-air long term experiment;
(4) collecting and sampling of the present invention is convenient, and the percolating water turbidity of collecting is little, is easy to measure.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, pipe 2, leakage water collecting hole
Embodiment
Further specify technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
A kind of plough layer soil percolating water collecting device as shown in Figure 1 comprises the pipe 1 that the bottom is sealed, and described pipe 1 is divided into aerial part and under ground portion; Around the tube wall of the under ground portion top of pipe 1, be provided with some leakage water collectings hole 2; The top of pipe 1 is provided with the pipe lid.
During use, with the common PVC plastic drain-pipe of length 2.2m, the internal diameter 8cm material as the leakage water collecting device, bottom sealing, guarantee to seal water-tight, add a cover on the top, prevents that foreign material and rainwater from entering; Be about the leakage water collecting hole that 8mm, pitch of holes are about 10mm at the uniform diameter that processes around the pvc pipe of top 45cm to 75cm, outside this section pvc pipe, wrap up the plastics gauze then, prevent that soil or sand grains from entering.
Use when installing, on the farmland massif of choosing, dig out the soil pit of a dark 2m, diameter 1m, the leakage water collecting device is uprightly put into, use the undisturbed soil backfill again, under ground portion carries out landfill according to following requirement:
(1) 0~0.25m: fill the space with topsoil;
(2) 0.25~0.55m: fill the space with silica sand;
(3) 0.55~2m: fill space and compacting with the undisturbed soil that digs out.
