However, even though the importance of fine roots has been suggested, it is difficult to collect fine roots, so there is a problem that they are difficult to survey compared to thick roots such as taproots and primary roots, which are relatively easy to collect. there were.
Methods for collecting fine roots of plants cultivated in Wagner pots include a method of picking up fine roots from the soil in the pot using tweezers, and a method of pouring water over the root ball to wash away the soil in the rhizosphere.
FIG. 9 shows a conventional method of washing out the roots while pouring tap water.
As shown in FIGS. 9(a) and 9(b), the roots in the pot are taken out together with the soil into a container, and as shown in FIGS. 9(c) and 9(d), water is applied from the roots to After removing the soil and removing the soil-free root stump as shown in FIG. 9(e), the torn roots are picked up as shown in FIG. 9(f).
Patent document 1 proposes a root system collection device and a root system collection method using a root box for cultivating plants and a pinboard.
