Field-crop rhizosphere soil solution situ sampling device as above, described catheter and scavenge trunk are white translucent polyethylene hose, and internal diameter is identical, and openend is all furnished with Plastic cap.
Compared with prior art, the beneficial effects of the utility model are:
The utility model solves existing field-crop rhizosphere soil solution sampling apparatus complex structure, draw materials and assemble not easily, cost of manufacture is high, use the problems such as complex operation, to China's present stage soil liquid sampling, particularly field-crop rhizosphere soil solution in situ sampling has great application value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model field-crop rhizosphere soil solution situ sampling device.
In figure: 1-soil liquid collection tube, 2-catheter, 3-syringe, 4-scavenge trunk, 11-water seepage hole, 12-plastic gauze, 13-plug.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the structural representation of the utility model field-crop rhizosphere soil solution situ sampling device, described field-crop rhizosphere soil solution situ sampling device comprises soil liquid collection tube 1, catheter 2, syringe 3 and scavenge trunk 4.Described soil liquid collection tube 1 main body is pvc pipe, and pvc pipe stage casing surrounding is drilled with water seepage hole 11, and is fastened by tube wall parcel in water seepage hole 11 place with plastic gauze 12, and pvc pipe both-side opening end plug 13 seals.Described plug 13 is provided with through hole, and catheter 2 is connected with soil liquid collection tube 1 by the through hole respectively by plug 13 with scavenge trunk 4.Described soil liquid collection tube 1 imbeds the predetermined depth of agricultural land soil according to crop root distribution situation, level is embedding.Described syringe 3 is common medical syringe, is connected with catheter 2, for drawing the soil liquid in soil liquid collection tube 1.Described catheter 2 and scavenge trunk 4 are white translucent polyethylene hose, and internal diameter is identical, and openend is all furnished with Plastic cap.
In use procedure, by soil liquid collection tube 1 horizontal positioned and adopt flexible catheter 2 and scavenge trunk 4 to be for effectively avoiding the moisture of rainfall or irrigation to infiltrate along vertical tube wall the edge effect caused downwards.
The agricultural land soil liquor capacity that the pipe diameter size of soil liquid collection tube 1 and length are optionally collected and determining.The depth of burying of soil liquid collection tube 1 is depending on crops and Root Distribution situation thereof.Syringe 3 amount of capacity is depending on solution sampling quantity demand, and catheter 2 and scavenge trunk 4 internal diameter need match with syringe 3.
The using method of field-crop rhizosphere soil solution situ sampling device, comprises the following steps:
