Description
Technical field
The present invention relates to soil nutrient migration rule studying technological domain, particularly relate to a kind of native fish device.
Background technology
Current most of soil-column test devices use the easy device that PVC material or lucite are made, only under pillar
End punching receive leaching liquor or install simple funnel receive the bottom leaching liquor, this device advantage be simple to operate easily
OK.For different tests, having preset the soil layer height of leaching, such as pillar makes 20cm to 120cm, diameter
10-30cm, shape differs.If soil layer is higher than 20cm, artificial hands cannot compacting soil, it is necessary to by instrument by soil
It is compacted layer by layer, in case upper layer of soil subsides downwards when watering.Require to choose whether planting plants for difference.Shortcoming: Bu Nengji
Time effectively measure the nutrient dynamic change of each soil layer.
Dynamically change to measure the nutrients movement of each soil layer on this basis, use in-situ soil layering to fill, each
Soil layer layering arranges leaching liquor and receives.Device is most at present the side at earth pillar and bottommost punch, and use rubber tube to insert
In the middle part of side, and nylon net cloth (general employing 100-200 mesh nylon net cloth, it is therefore an objective to anti-is wrapped in perforating on rubber tube
Only soil particle enters rubber tube, blocks rubber tube), outside employing latex or transparent adhesive tape adhesive seal, be fixed on earth pillar side.
Rubber tube opposite side glass tubing and thinner hose connect.Tongs is used to control whether to receive leaching liquor on hose.
Advantage: the leaching situation of each layer soil can be monitored at any time.Shortcoming: 1. perforating on rubber tube, the size of the eye that leaks is indefinite, needs root
The border soil texture etc. are tested factually, repeatedly adjust；2. the selection of rubber tube is critically important, need to use thicker on-deformable rubber
(repeatedly the leaching test of interval easily causes the deformation of soil inner rubber pipe to sebific duct, curved under rubber tube, not in level, affects leaching
The outflow of liquid；The soil layer position, place of the leaching liquor being simultaneously received is it is possible that deviation)；3. side uses latex or transparent
Glue seals, and sealing property has to be strengthened；4. use glass tubing to connect hose, control switch, operating procedure with tongs
More.

Detailed description of the invention
Embodiment 1
As Figure 1-5, a kind of native fish device, including device body 1, the described device body 1 column structure in hollow,
It is vertically arranged with the reception device 2 of 4 levels on described device body 1, is positioned at reception device topmost 2 and described device
On body 1, the vertical dimension on edge is 30cm, and the adjacent vertical dimension between described reception device 2 is 20cm, adjacent described in connect
Device body 1 between receiving apparatus 2 is threaded, makes whole device body 1 be divided into four splits 5, split 5 upper end to be provided with
Female thread 51, lower end is provided with external screw thread 52, and this structure more convenient layering interpolation soil and test take out soil after completing, described
Receiving device 2 to be horizontally placed in described device body 1, described reception device 2 upper surface is provided with bar v notch v 21, described scarce
Covering nylon wire 22 on mouth 21, be used for preventing soil particle from entering and receive in device 2, described reception device 2 one end is sealing knot
Structure, the other end extends to the described outer rear flank of device body 1 and connects faucet 3；Described device body 1 bottom thread is connected with
Bottom 4, described bottom 4 is provided above drainage screen with the junction of described device body 1, and described bottom 4 bottom is provided with logical
Hole.
Use process:
First, the section folk song taken is done, crosses 2mm sieve, insert the device body 1 of earth pillar by unit weight layering, fill from the bottom up,
Smearing the side of pillar with vaseline, reduce border effect, soil layer filter screen (can use the nylon net cloth of 200 mesh) top loads 2-
Quartz sand thick for 3cm can flow out earth pillar equably as loaded filter, the aqueous solution using stream, prevent earth pillar lower end soil particle
Flow out with water.By soil sample by the corresponding unit weight loading earth pillar of every layer, (every layer of soil sample thickness is 20cm, calculates this height according to unit weight
The soil sample weight filled out needed in degree earth pillar volume), at layering, dig hair be beneficial to combination between layers.
Again, after loading four layers of soil sample, the empty 10cm of the superiors, 10-30cm soil layer is that soil sample mixes with fertilizer, according to soil
Post dose is 2 times of calculating fertilizer amounts of land for growing field crops dose, mixes charging apparatus body 1 with soil sample after being pulverized by fertilizer, and
In the superiors' layer overlay filter paper, pad upper filter screen the quartz sand in upper loading 2-3cm thickness, the water become a mandarin is enable to enter equably
Enter in device body 1, prevent device body 1 upper end from destroying Soil structure because water impact forms depression.Device body 1 top
Seal up the preservative film with a small amount of pin hole, in order to prevent evaporation of water, the most do not affect the leaching speed of water.
Finally, calculate irrigation quantity (irrigation quantity calculates with evaporation capacity) according to local irrigation quantity, precipitation according to practical situation,
Using drip irrigation to water makes earth pillar satisfy water.Earth pillar is satisfied after water, cultivates one day, irrigate with distilled water afterwards under room temperature, every
Within three days, pouring water once, layering receives leaching liquor.First close all faucet, open the superiors' faucet, receive leaching liquor, work as pouring
(need setting to connect the leaching liquor time also dependent on test, the time of reaching is followed by accepting one layer of leaching liquor) after solution reaches 50mL and close
Close a layer faucet, open second faucet and go to connect leaching liquor, successively receive, measure.
Embodiment 2
