A kind of installation and application of the soil nutrient leakage loss monitoring device of Karst region, the method step are as follows: one,
Choosing in Karst Rocky Desertification Region has typicalness and representative different land use type；Two, in each land use
Apart from the position of plant root 20cm in type, a long 50cm × wide 50cm × depth 50cm pit is dug, is formed vertically downward
Four soil profiles；Three, the hole that four diameters are 5cm is dug on four vertical soil sections of pit respectively, hole depth is
20cm, hole are respectively 10 cm, 20 cm, 30 cm and 40 cm from the distance between soil surface；Four, four soil liquid are adopted
Sample device is respectively put into the hole in step 3, then is filled up hole with soil and do not left a blank；Five, the soil in soil is extracted in rainfall season
Solution sampler takes out the moisture wherein collected and takes back experimental determination nutrient content, and the soil of comparison different soil depth is supported
Divide content, the leakage mechanism of soil nutrient can be disclosed.
The beneficial effects of the present invention are: compared with prior art, using technical solution of the present invention, the technical program passes through
After stony desertification comprehensive treatment demonstration area vegetation pattern, agrotype and topography and geomorphology feature are grasped in network analysis, selection has allusion quotation
Type and representative sample ground type, pass through and install soil moisture collector in sample ground.System, accurately monitors science
Soil nutrient is influenced by rainfall size in sample ground, discloses influence of the Karst region leakage moisture to loss of soil nutrient.Together
When avoid it is traditional artificial adopt soil sample measurement nutrient, it is cumbersome and time consuming.And this method dynamic reflects Nutrient rainfall
The wastage of amount, data are true and reliable.
