specific Embodiment approach 1

[0008] Specific implementation mode one: combine figure 1 Describe this embodiment, a plant root growth box suitable for rhizosphere research described in this embodiment includes two boards 1, two strip clips 2 and two cellophane 4, two strip clips 2 are arranged side by side in two Between the boards 1, two boards 1 and two strip clips 2 form a box body 3 without a bottom and a cover. The inner wall of each board 1 is provided with a cellophane 4 along the length direction, and the lower end of each cellophane 4 extends to the box. Body 3 is external and embedded in a sand bath. In this embodiment, the lower part of the box body 3 is fixed on the fine sand bath provided with nutrient solution, and the bottom of the box body 3 is evenly placed with 0.5 cm thick stones or glass beads with a diameter of 2mm-3mm to block the sand. With the capillary action of the soil in the box body 3, the soil for the test is filled in the box body 3 and the plants are sown. This embodiment e...

[0010] Specific implementation mode three: combination figure 1 To illustrate this embodiment, the two boards 1 of a plant root growth box suitable for rhizosphere research described in this embodiment are boards 1 made of PVC material, and the two bar clips 2 are bar clips 2 made of PVC. This embodiment prolongs the service life of the invention. Other compositions and connections are the same as those in Embodiment 1 or 2.

[0011] working principle

[0012] The lower part of the cellophane 4 is buried in the bottom of the sand bath, the box body 3 is fixed on the fine sand bath provided with nutrient solution, and the bottom of the box body 3 is evenly placed with 0.5 cm thick stones or glass beads with a diameter of 2mm-3mm. To block the capillary action of the sand and the soil in the box body 3, prevent the moisture in the soil capillary sand bath in the box body 3 from being supersaturated, put the soil for the test into the box body 3, and after filling, the upper su...

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 [0001] The invention relates to a growth box, in particular to a plant root growth box suitable for rhizosphere research. Background technique [0002] As a special system in the soil ecosystem, the rhizosphere is affected by the activities of plant roots. It is different from the micro-soil area of ​​soil in terms of physicochemical and biological properties. It is the interface formed by the interaction between roots, soil and microorganisms. Plants are In the dominant aspect of the rhizosphere micro-ecosystem, different plants have different root morphology and physiological metabolism characteristics, even different genotypes of the same plant also have differences, which will inevitably produce different rhizosphere effects, which will affect the transformation of nutrients in the rhizosphere micro-domain. , the availability of soil nutrients and crop growth and development have a direct impact. [0003] In the field of rhizosphere research, the root bo...
