Description
Technical field
The utility model relates to edaphology field, particularly a kind of root system sampler.
Background technology
At present, in the concrete research practice in actual field, the sampling specific operation process of distributing for Steppe Plants Population breeding stock biomass comprises the following aspects:
1, breed stock biomass and distribute sampler employing core cutter method, heavy caliber cutting ring (diameter is 20cm, high 30-40cm, and thickness is 7mm, and this cutting ring volume participates in data and calculates, i.e. fixed volume sampling) sampling;
2, during field sampling, hammer (18 pounds or 24 pounds) is adopted directly to insert in soil by cutting ring according to the scale marker above cutting ring;
3, cutting ring inserts after in respective depth soil, then is cut open by cutting ring surrounding soil with instruments such as spades, takes out cutting ring and loads in car after backfilling heatable adobe sleeping platform, taking back laboratory and be for further processing and analysis;
4, after laboratory taken back by cutting ring, first the undisturbed soil sample lifting jack in cutting ring is ejected (undisturbed soil sample is ejected from bottom to top), load in the nylon net bag of suitable size, under the flushing of giant, clean up the whole strain plant individual of rear acquisition (strain clump), decompose corresponding brood body component, dry under being placed in constant temperature and claim its corresponding weight (modular organism amount) to constant weight, distribute the measured data of Bomass allocation as plant propagation.
But there is following shortcoming in current root system sampling method:
1, cutting ring is not portable; Easily there is double swerve when sampling with cutting ring, affect sampling precision; Although cutting ring is inserted in the process of soil at use hammer, cutting ring top is lined with wooden unit to protect cutting ring, but the easy landing of wooden unit in concrete operations, hammer often directly pounds cutting ring edge, cutting ring is very easily made to be out of shape, even injure test clerk, impact sampling safety and sampling precision, differing greatly of test the data obtained; And hammer has certain destruction to cutting ring, cause the recycling rate of waterused of cutting ring lower, not only waste resource, and consuming timely to take a lot of work, field work efficiency significantly reduces.
2, after cutting ring inserts soil respective depth, need to be cut open by the soil around cutting ring with instruments such as spades, thus can form a heatable adobe sleeping platform around cutting ring, for test plot (or meadow), heatable adobe sleeping platform then belongs to destructive influences; If when large-scale experiment design needs to gather a greater number sample, field sample collection only involved by this research contents then can produce greatly destruction to meadow, and sample ground managerial personnel or herdsman can not allow (or authorize) related scientific research personnel to go the scientific experimentation activity carrying out being correlated with entering sample.
3, because undisturbed soil contact area in lifting jack and cutting ring is less, discontinuity, undisturbed soil is not easily ejected, and wastes time and energy, inefficiency; In cutting ring, original-state soil is vulnerable to the disturbance (or destruction) of lifting jack, damage plant individual plant (strain clump) root system, originally can be separated with maternal plant individuality (strain clump) after complete root system damages, root system after separation can not participate in statistical study when subsequent data analysis, accuracy and the validity of data obviously reduce, and the reliability of scientific research result then decreases.
4, in above-mentioned sampling method, when the required specimen sample amount gathered of experimental study is more, then need a large amount of large cutting rings, namely often gathering a sample just needs a cutting ring.Even if sample in batches, the cutting ring of sufficient amount also must be needed could to meet the demand of sample collection.Visible, the corresponding showed increased of test material expense, and the recycling rate of waterused of cutting ring is lower, serious waste of resources.
When 5, sampling in batches, each cutting ring needs a corresponding supporting nylon net bag, and when sample size is more, expending of nylon net bag is also very large, really there is the phenomenon of certain wasting of resources.
6, cutting ring lower end sawtooth is blade wedge shape, often runs into relatively large stone childhood when cutting ring inserts soil, and blade will rust distortion, and cutting ring can be damaged phenomenon at any time; Because grassland soil is without interference original-state soil, consolidation is strong, even if adopt the sampling of blade-like cutting ring, process cutting ring being inserted soil also comparatively wastes time and energy.
