Description
Technical field
The present invention relates to the collection equipment of plant specimen, especially a kind of combined quantitative sampler that is used to study root system of plant distribution and root morphology.
Background technology
Crop root is the important Nutrient Absorption organ of crop; also be the fixedly organ of crop simultaneously; promote root growth and development; form eurythmy, the suitable root mass of distribution; be the important content of agricultural management and protection, bad as root system development, it is shallow to distribute; crop yield is not high, also lodges easily.Crop root is distributed widely in the soil, brings very big difficulty for observation and research work.At present, observe root system field distribution situation, mainly contain root and drill through two kinds of local method, profile methods: it is the barreled sampler that an internal diameter is 5cm that root bores, be pressed into soil by external force after, soil zone is gone out.Because it is little that root bores internal diameter, that takes out of is native limited, adds that root distribution randomness in soil is big, and significant limitation is arranged in application.Profile method is by excavating a soil profile, and layering is fetched earth from top to bottom on section, is isolating root by suitable approach from soil.Many in operation instruments with little scoop and so on, the long-pending quantification degree of the soil body of being got is poor, handwork, efficient is not high yet, be difficult to adapt to the needs of a large amount of investigation, simultaneously institute fetch earth scattered, root system breaking releasing very easily in sampling process, form little root segment in small, broken bits, make troubles for the operation of follow-up collection root.
Summary of the invention
The present invention is in order to solve the investigation to the plant roots distribution situation, the instrument of little scoop that is adopted and so on, the quantification degree is poor, handwork, efficient is low, be difficult to adapt to the needs of a large amount of investigation,, provide a kind of combined quantitative sampler that root system of plant distributes and root morphology is learned that is used to study by appropriate design, realization is to the soil of Root Distribution, the collection of fast quantificationization, convenient and reliable operation is guaranteed the sample ecosystem.
The present invention is for realizing above-mentioned goal of the invention, adopt following technical scheme: sampler is the casing at the no top cover and the no end, the four sides of casing is dismantled and assembled, and the front and back ends panel is set to end plates A, and the inboard correspondence in A group panel two ends is provided with T-slot, the left and right side panel is set to the B group, the two ends of B group side panel are designed to T shape key, the T-slot on the T shape key corresponding A group panel, and casing upper surface level is put, casing lower surface horizontal parallel, four panel lower ends of casing cutting edge arranged outside, 30 degree angles.
During soil sampling, the end plates A of sampler, side panel B down-bite jaw horizontal positioned on the ground, by ram engine or manually squeeze in the soil, to after native face is concordant, excavate the soil of a side along the sampler outer wall, then, other gets a panel, and cutting edge inwardly, in the lower edge level incision soil of sampler, can connect the soil zone sampler easily and take out together.
Wherein the spacing of two panel grooves of A group has determined the length of the piece that fetches earth; The width of B group width panel decision institute soil sampling; The thickness of the panel height decision institute soil sampling of A group and B face.The long 214mm of A panel of the present invention, thick 3mm, high 100mm, the dark 2mm of groove, the wide 6mm of groove, the long 80mm of groove, two flute pitch 200mm.Groove extends downwards from A panel upper end open.Put the first edge on a knife or a pair of scissors in A panel lower end, cutting edge is outside.The long 102mm of B panel, thick 2mm, high 100mm, put the first edge on a knife or a pair of scissors in B panel lower end, and cutting edge is outside.A wide 5.5mm is welded according to the direction perpendicular to the B panel respectively in both sides, thick 1mm, and the plug tenon of long 80mm, it aligns with the B panel away from edge of a knife section.Wherein the length of A, B panel, height can customize according to concrete experiment demand.When soil sampling, the sampler horizontal setting on the ground, by ram engine or manually squeeze in the soil, to with after native face is concordant, excavate the soil of a side along the sampler outer wall, then, other gets a panel, in the lower edge level incision soil of sampler, can connect the soil zone sampler easily and take out together.Dismantle panel, and obtain a harmless pedotheque, comprising the original distribution situation of root system of plant in soil.If in conjunction with the X scanning technique, soil block is carried out X scanning, and can get the concrete three-dimensional distribution situation of root system in the soil.If different soil blocks, the result after scanning according to the space distribution situation connection of nature, just can obtain the NATURAL DISTRIBUTION situation of root system in the whole investigation soil layer.Certainly,, root morphology is carried out the analysis of microcosmic if, can from soil, isolate root system after the soil block employing spreading agent immersion dispersion, also can be for other purposes.
Beneficial effect, reasonable in design, succinct reliable, but the dismounting of Fast Installation box, easy to carry, be easy to safeguard that it is original that the gained soil sampling can keep, destroy little to the root system in the soil block, both be suitable for using X-ray scanning, also can be used for extracting the root system sample, quantitative accuracy height, sampling efficiency height.
