Abstract
The invention provides a plant root system growth chamber applicable to rhizosphere research, and relates to a growth chamber, which is used for solving the problems that as space of a root box is narrow and small, growth of a root system is limited, and growth and physiological properties of the root system are changed to affect rhizosphere effect in the existing rhizo-box method for collecting rhizosphere soil. The plant root system growth chamber provided by the invention comprises two plates, two strip clips and two glass paper, wherein, the two strip clips are arranged between the twp plates in parallel; the two plates and the two strip clips form a bottomless and uncovered box body; the inner wall of each plate is provided with one glass paper along the vertical direction; and the lower end of each glass paper extends to the outside of the box body and is embedded into a sand bath. The plant root system growth chamber provided by the invention is used for planting plants on the sand bath and carrying out plant rhizoshpere research.
Description
Technical field
The present invention relates to a kind of growth case, be specifically related to a kind of plant root growth case that is suitable for rhizosphere research.
Background technology
rhizosphere is to be subjected to the root system of plant Activity Effects as a special system in soil ecosystem, the little territory Tu Qu that is different from the soil body on physico chemistry and biological property, it is the interface that root system and soil and microbial interaction form, plant is the leading factor of rhizosphere microecological system, different plant root species forms and physiological metabolism feature are different, even the different genotype of same plant also there are differences, this certainly will produce different rhizosphere effects, this conversion to nutriment in rhizosphere micro-region, the validity of soil nutrient and crop growth etc. have a direct impact.
In the rhizosphere research field, root case method is a kind of accepting extensively at present and more effective Rhizosphere Soil collection method.Existing root case method Rhizosphere Soil collection method root case narrow space has limited Root growth, has changed root growth and physiological property, has affected rhizosphere effect.
Summary of the invention
The present invention has limited Root growth for solving existing root case method Rhizosphere Soil collection method root case narrow space, has changed root growth and physiological property, has affected the problem of rhizosphere effect, and then proposes a kind of plant root growth case that is suitable for rhizosphere research.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes two boards, two bar folders and two glassine papers, two bar folders are set in parallel between two boards side by side, two boards and two bars folder consist of the box body of bottomless a, uncovered, every plate inwall vertically is provided with a glassine paper, and the lower end of every glassine paper extends to the box body outside and embeds in sand-bath.
The invention has the beneficial effects as follows: the present invention can grow in sand-bath by the bottom of box body the root system of plant, and then has discharged the Root growth space; Sand-bath provides nutrient simultaneously, has avoided plant nutrition to coerce, and has guaranteed the normal unrestraint growth of plant; And the nature of glass can absorb the humidity that moisture guarantees soil in the root case from sand-bath, avoids watering from the root upper box part and causes the soil nutrient leaching.The present invention has guaranteed the normal of plant root growth and physiological property, and has not affected rhizosphere effect for plant root growth provides larger growing space.

Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, the described a kind of plant root growth case that is suitable for rhizosphere research of present embodiment comprises two boards 1,2 and two glassine papers 4 of two bar folders, two bar folders 2 are set in parallel between two boards 1 side by side, two boards 1 and two bars folder 2 consist of the box body 3 of bottomless a, uncovered, every plate 1 inwall vertically is provided with a glassine paper 4, and the lower end of every glassine paper 4 extends to box body 3 outsides and embeds in sand-bath.bottom with box body 3 in present embodiment is fixed in the fine sand bath of nutritious liquid supply, the bottom even pad of box body 3 is put stone or the bead that the thick diameter of 0.5cm is 2mm-3mm, in order to block the capillarity of sand and box body 3 interior soil, load the soil that is for experiment in box body 3 and sow plant, present embodiment has guaranteed that the root system of plant can grow into by the bottom of box body 3 in sand-bath, and then discharged the Root growth space, simultaneously also avoided plant nutrition to coerce, guaranteed the normal unrestraint growth of plant, in present embodiment, the bottom of glassine paper 4 is imbedded bottom sand-bath, in order to absorb moisture from sand-bath, nutrient enters box body 3 inside, present embodiment has been avoided watering from box body 3 tops and has been caused the leaching of the intrinsic nutrient in soil Central Plains, and change soil physical and chemical property.
Embodiment two: present embodiment is described in conjunction with Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the long L of every block of plate 1 of the described a kind of plant root growth case that is suitable for rhizosphere research of present embodiment is 15cm, wide W is 12cm, thickness H is 0.5cm, the long A of each folder 2 is 15cm, and wide B is 1cm, and thickness C is 0.5-1cm, the long D of glassine paper 4 is 20cm, and wide E is 10cm.Other composition and annexation are identical with embodiment one.
Embodiment three: in conjunction with Fig. 1, present embodiment is described, the described a kind of two boards 1 that is suitable for the plant root growth case of rhizosphere research of present embodiment is that 1, two bar folder 2 of plate of being made by the PVC material is bar folders 2 of being made by PVC.Present embodiment has extended service life of the present invention.Other composition and annexation are identical with embodiment one or two.
Operation principle
sand-bath bottom is imbedded in the bottom of glassine paper 4, the fine sand that box body 3 is fixed on nutritious liquid supply is bathed, box body 3 bottom even pads are put stone or the bead that the thick diameter of 0.5cm is 2mm-3mm, in order to block the capillarity of sand and box body 3 interior soil, prevent the interior soil capillarity fine sand of box body 3 in bathing moisture and supersaturation, the soil that is for experiment is packed in box body 3, load complete rear soil upper surface and box body 3 upper surfaces distances and be 2cm, nutrient solution is sneaked in sand-bath, adding water makes 2cm-3cm place, sand-bath bottom keep the saturation moisture state, by the time can sow after box body 3 internal upper part ground moistenings, earthing 2cm.Guarantee that like this root system of plant is grown under moisture and the suitable condition of nutrient all the time, and root growth is not subjected to the restriction in space, rhizosphere effect can be given full play to.
