Description
Technical field
The utility model relates to a kind of crop root stratified sampling instrument, belongs to agrotechnique apparatus field.
Background technology
Root system is as one of three large organs of plant, in process of crop growth, play absorption, support and fixing vital role, not only absorb moisture and nutrient, the place of synthesizing amino acid and multiple hormone especially, there is close material exchange with overground part, for plant strain growth and output, form most important.Yet because crop root is grown in undergroundly, sampling, measures and observe and all have certain difficulty, so research is compared with aerial part and is also had larger gap about crop root.Root system sampling is a vital step in root system research, conventional method comprises mining method and non-excavating method two classes, non-excavating fado adopts the mode of non-earth culture to be beneficial to sampling, can not reflect the characteristic of crop root under soil completely, excavate rule and comprise mesh bag method, root case method, boring method, direct mining method etc., wherein root case method can be for studying the space distribution situation of crop root, but need to make a large amount of root casees and carry out pre-buriedly, implements difficulty larger.A kind of crop root stratified sampling device that the utility model is related, simple in structure, easy to operate, can carry out the horizontal stroke of crop root, the stratified sampling of vertical both direction, on sampling method, belong to boring method.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of crop root stratified sampling device, can be used in the root system sampling of the crops such as paddy rice, wheat, soybean, rape, and can reach the object that two dimensions of root system vertical and horizontal are carried out layering, for facilitating the sampling of crop root research to there is vital role.
For achieving the above object, the utility model adopts following technical scheme:
A kind of crop root stratified sampling device comprises cylinder drill bit, inserts axle and strike and press cake three parts.
Totally 3 of described cylinder drill bits, internal diameter is respectively 6,12 and 18cm, root system can be divided into interior, in, outer 3 layers.The high 35cm of described cylinder drill bit, cutting edge is arranged at bottom, considers that diameter is larger, and soil-entering resistance is larger, higher to drill bit requirement of strength, so three bit wall thickness are designed to 2,3 and 4mm successively.Two pairs of orthogonal jacks are arranged at described cylinder drill bit top, are respectively jack and lower jack, upper jack distance of center circle top 18mm, and lower jack distance of center circle top 38mm, diameter is all 20mm, for assigning lock shaft.
Totally two of described lock shafts, look in upper jack for one, and one inserts in lower jack, with nut screwing clamping, locks.The about 38.5cm of described lock shaft length, after insertion cylinder drill bit, two ends are respectively exposed one section as handle, by three cylinder drill bits can be rotated or extract to hand operation simultaneously.Described lock shaft centre and right-hand member diameter are 18mm, and middle boss diameter is 26mm, between left end and interlude, has screw thread, the long 20mm of screw thread, and for ease of inserting and nut lock, left end diameter is slightly little, is 15mm.Described three cylinder drill bits can first press cake to be driven underground successively by knocking respectively, then by lock shaft, connect as one, from underground taking-up cylinder drill bit and root system soil sample, in finally from cylinder drill bit, taking-up is laterally divided into, in, the root system soil sample of outer 3 layers, in taking out the process of soil sample, first back out nut, take out lock shaft, then by outermost layer cylinder drill bit down sliding, with cutter, according to test, need the root soil of certain depth under ring cutting, successively glide, ring cutting successively, to reach the longitudinal layered object of root system, after outer root system cuts, slide successively middle level cylinder drill bit and inner layer cylinder drill bit, in inciting somebody to action by that analogy, in, outer 3 layers of soil sample are carried out longitudinal layered.
Describedly strike that to press cake lower end be patty, thick 10mm, diameter 200mm, cake bottom is processed with 3 circle circumferential draw-in grooves, be used for the process of knocking and locate three cylinder drill bits, described draw-in groove width for being respectively from inside to outside 3,4,5mm, dark 4mm, for guaranteeing to strike, press cake indeformable in the process of knocking, cake center, bottom thickness is 20mm.Described cake welded top is knocked axle, knocks this axle cylinder drill bit is driven underground by hammer.The described shaft diameter 28mm that knocks, high 240mm, top is hammer shape, is conducive to knock.
In sum, owing to having taked above technical scheme, the beneficial effects of the utility model are:
Crop root stratified sampling device of the present utility model, simple in structure, easy to operate, use flexibly, while only using one of them cylinder drill bit, can realize the integral body sampling of crop root, use a plurality of horizontal stratified samplings that can realize crop root, take out and also can realize by ring cutting after soil sample longitudinal layeredly, can meet the sampling demand of research crop root Concentration;
Crop root stratified sampling device of the present utility model, because 3 drill bits are that the root soil that carries out again after taking out is together longitudinal layered, thereby can effectively improve the flatness of sampling soil bottom with respect to disposable fetching earth, and after avoiding root soil to take out, be scattered, to root system layered, bring adverse effect.
The dirigibility of crop root stratified sampling device of the present utility model is also, when because soil is comparatively hard, cylinder drill bit is squeezed into soil very at need by disposable, can adopt gradation to squeeze into the mode of cylinder drill bit, samples several times.
Crop root stratified sampling device of the present utility model, in to the less demanding situation of sampling diameter, can directly adopt the approaching steel pipe processing and manufacturing of size, with low cost, can design suitable dimension according to the Root Characters of Different Crop, thereby there is wider usable range.
