Field sampling point is hammered into shape using rubber lead for retractable pencil, leaching column 52 is struck to the soil depth of needs, integrally to take out together with soil.
When knocking in, the side of leaching column 52 need to be smeared, with vaseline to reduce edge effect.It is filled below the intracavitary earth pillar of 52 column of leaching column
Enter four layers of filter structure, so that earth pillar can equably be flowed out by using the aqueous solution of stream, prevents earth pillar lower end soil particle with water
Outflow.Soil sample weight in the height earth pillar volume is calculated according to bulk density.
After being packed into soil sample, vacant 10cm of top layer or so so as to atomizer 55 receiving.According to earth pillar nutrient demand
Amount is that the three times of crop field nutrient requirement rate calculate nutrient dosage, thus nutrient chemical is mixed with soil sample be fitted into liquid storage bottle 10 and
Form leaching liquor.In earth pillar top layer layer overlay filter paper layer, upper filter screen layer is padded and second quartz thick in 2~3cm of upper loading
Layer of sand prevents soil layer upper end from destroying soil texture due to water impact forms and is recessed, influences the leaching speed of water.
Finally, needing irrigation quantity according to what local irrigation quantity, precipitation and evaporation capacity calculated earth pillar, made using trickle irrigation watering
Earth pillar is satisfied water.Earth pillar is satisfied after water, is cultivated three days, is irrigated later with distilled water at room temperature, is poured water primary, is led to every three days
It crosses and simulates all kinds of rainfall degree, and control the switch valve 57a of 52 bottom end leaching liquor of leaching column outlet, leaching can be collected at regular time and quantity
Liquid.After the leaching liquor gone out via 57 drippage of funnel-form sealing is collected, subsequent measurements operation can be carried out.
