[0030] The mixed saline-alkali soil is loaded into the outer barrel 1 and the inner mesh basket 2, and the soil does not exceed the height of the outer barrel 1 and the inner mesh basket 2, and a phragmites australis root with a bud seedling is planted in each planting area, and different water levels or nutrient treatments are carried out according to experimental requirements until the end of the experiment. Due to the growth of the phragmites australis root system under sufficient water conditions, the mesh structure of the inner mesh basket 2 and the first mesh 3 can prevent the root system from growing outward and mainly concentrate in the inner mesh basket 2. Due to the water permeability of the inner mesh basket 2, the soil conditions inside and outside the inner mesh basket 2 are consistent, so the soil outside the inner mesh basket 2 can be used as non-rhizosphere soil, and the soil inside the inner mesh basket 2 containing the root system is rhizosphere soil, and the multiple second meshes 5 arranged inside can effectively separate the root system of each phragmites australis and the development of the new root-like stem, facilitating the statistics of individual growth indexes. When the soil needs to be collected, the inner mesh basket 2 is taken out of the outer barrel 1, and then the inner mesh basket 2 and the first mesh 3 are removed; thus the rhizosphere soil of each plant can be collected, and the accuracy of rhizosphere soil collection is improved.

[0031] Further optimization scheme, the outer side wall of the inner mesh basket 2 is clamped with a plurality of clamping rings 6, and the first mesh 3 is clamped between the outer side wall of the inner mesh basket 2 and the clamping ring 6.

[0036] Further optimization scheme, the height of the inner mesh basket 2 is lower than the height of the outer barrel 1.

[0037] In use, this invention involves filling the outer bucket 1 and inner mesh basket 2 with well-mixed saline-alkali soil to a depth of 25cm, compacting the soil, and ensuring the soil surface is 10cm from the upper edge of the inner mesh basket 2 and 15cm from the upper edge of the outer bucket 1. The water outlet pipe 11 is positioned directly above the soil. Sufficient water is then added, and once the soil is moistened, reed rhizomes are transplanted. Four healthy reed rhizomes with buds are planted in four separate planting spaces. After the seedlings have recovered, water is gradually added to a depth of 10cm based on their growth rate. Different water levels or nutrient treatments are applied as needed for the experiment until completion. After four months of reed growth, the root system fills the planting area of ​​the inner mesh basket 2. The plug 12 is opened to drain the water. The inner mesh basket 2 is then gently rotated back and forth before being lifted out entirely. The inner mesh basket 2 is cut open, and the rhizosphere soil of each plant is collected. Finally, the soil from the outer bucket 1 is collected as non-rhizosphere soil for comparative analysis.
