Abstract
Root growth and the experimental rig of nutrients movement elution under field condition are simulated, belongs to soil and botany technical field.It includes test chamber, the cylindrical structure of the outer upper and lower opening of described test chamber, described test chamber surface is provided with graduation mark, described test chamber bottom is arranged in the middle part of bottom plate, described bottom plate is provided with osculum, drainpipe is equipped with described osculum, filtrate receiving flask is equipped with below described drainpipe.The real time measure soil eluviation liquid volume and nutrient elution loss amount under field condition can be simulated using device of the present utility model, while destructive sampling is carried out in off-test, soil nutrient migration can be studied and be distributed the influence to root growth.
Description
Technical field
The utility model belongs to soil and botany technical field, and in particular to root growth is with supporting under simulation field condition
Partite transport moves the experimental rig of elution.
Background technology
Moving distribution of the nutrient in soil is one of key factor for influenceing crop root growth, while nutrient elutes
Crop root scope enter body of groundwater be also to cause nutrientuse efficiency low, and the environmental hazard such as body eutrophication because
One of element.The influence that research soil nutrient is migrated to crop root growth at present, and soil nutrient elution loss are endangered to environment
Evil is the hot research field of the subjects such as agrology and Plant Nutrition.But under the conditions of being currently grown in the field, due to plant
Root system and soil nutrient are located in such a "black box" of soil, it is difficult in situ, intuitively observation plant root growth distribution.Pass
The root system sampling method of system often results in root system loss, influences data accuracy, and waste time and energy.So far not yet simultaneously
Have good test method can under in-site detecting field condition the experimental rig such as soil nutrient moving distribution and elution loss and
Research method.The invention device can provide a kind of new test method to solve above-mentioned technical barrier.
Utility model content

Drainpipe 5 is equipped with, the lower section of drainpipe 5 is equipped with filtrate receiving flask 6.
In use, A places experimental rig, different fertilizer is added in the diverse location of test chamber 1 according to experiment demand
Or the different tests such as soil processing；
B fills soil to cylinder top 5-10cm in test chamber 1；
Plant seedlings or vegetable seeds are planted in the centre position of test chamber 1 by C；
D monitors effusion volume and each nutrient content in filtrate receiving flask 6 according to test situation in real time；
Test chamber 1 is separated during E off-tests, and measure plant root species form and soil are layered according to test situation
Physicochemical property.
Example described above is only a case study on implementation of the present utility model, all not to limit this utility model
Any modification, replacement and improvement within the principle and spirit of invention etc., should be included in this protection of the present utility model
Within the scope of.
