Problems solved by technology

However, the root window method is still limited to drawing on the root window with acetate paper and other materials in image acquisition, which not only requires a lot of work, but also has poor image accuracy.
The micro-root canal method is currently a commonly used method for studying root dynamics. However, its main disadvantages are that it is expensive and the area of ​​each image observed is small, generally 2-3cm 2
No better method for studying root dynamics has been found so far, which severely limits the development of root ecology

Embodiment 1

[0015] Embodiment 1, digital camera method research root dynamics

[0016] 1. Fabrication and installation of glass root windows

[0017] More than 90% of the roots of grassland plant communities are distributed in the 0-30cm soil layer in the soil. Select a glass piece with a thickness of 0.4cm, a length of 20cm, and a height of 35cm. For the convenience of observation and analysis, a small square of 10cm×10cm is marked on the glass piece grid( figure 1 ), the marked area is 10cm×30cm, and the end close to the ground is close to the edge of the glass sheet. When installing, first use an iron plate to shovel out a plane along the vertical direction of the soil surface, then remove the soil on one side, remove the sundries, make the glass sheet closely contact with the soil profile, and then clamp it with iron bars on both sides of the glass sheet. Finally, backfill the soil. After 4-6 months of installation, the plant root system grows from the soil profile, and the growth ...

Embodiment 2

[0025] Embodiment 2, scanner method research root dynamics

[0026] 1. Sealing and installation of the scanner

[0027] Seal the ordinary office scanner (BenQ 5000S) with a plexiglass plate to ensure airtight and watertight. When sealing, seal the end of the data cable and power cable connected to the scanner together with the scanner, and leave the end connected to the computer outside and wrap it in a sealing bag. During installation, in the experimental area, first use an iron plate to shovel out a plane along the vertical direction of the soil surface, then remove the soil on one side, remove the sundries, and put the side scanned by the scanner in close contact with the soil profile on the undisturbed side Backfill the soil tightly, and leave the data line port and power line port connected to the computer wrapped in sealing bags on the ground. The upper edge of the scanning surface of the scanner should be about 1cm below the ground surface.

Abstract

The invention discloses a method for dynamically researching in-situ root system. The method prepares root windows at the plant root system part according to a root window method, obtains the root window pictures at different times, memorizes the pictures and uses a computer image processing analysis software to carry out quantitative analysis on the pictures. The computer image processing analysis software is the software of Mapinfo professional (version 5.0). The method photographs or scans the root window pictures respectively by a digital camera or a scanner. The method for dynamically researching the in-situ root system can obtain the root system observation pictures of large areas, has low cost and simple operation, is easier to be generalized and popularized and plays an active effect in promoting the development of national root system bionomics.

Description

technical field [0001] The invention relates to a method for studying root system dynamics in situ. Background technique [0002] The root system is an important organic organ of the plant. It not only has the function of absorbing nutrients and water, but also the production and turnover of the root system directly affect the biogeochemical cycle of carbon and nitrogen in the terrestrial ecosystem. Although the root system occupies a very important position in the terrestrial ecosystem, it is difficult for us to grasp the real growth status of the root system because the root system lives in the soil, so the research method of the root system has always been the bottleneck restricting the development of root system ecology. Therefore, the exploration of root research methods has always been an important aspect of the efforts of root ecologists. [0003] At present, the root-window method (Head G C. Shedding of roots[M]. In Shedding of Plant Parts. (Kozlowski T Ed.). New Yo...
