Abstract

The invention discloses a root division device for researching influence of rhizosphere soil microorganisms on root exudates and a use method of the device. The device comprises a base, the base is disc-shaped, an annular cylinder wall is fixed on the base, and a cylinder with an upper opening is formed; a plurality of vertical clamping grooves are uniformly distributed in the circumference of the outer wall of the cylinder wall, and the outer wall of the cylinder wall is slidably sleeved with a lifting ring through the clamping grooves; a through groove penetrating through the cylinder wall is formed in the middle of each clamping groove, the lifting rings penetrate through the through grooves to be connected with partition assemblies, and the partition assemblies can partition the radial space in the cylinder wall; and a collecting bag is arranged in the gap of each partition assembly, the collecting bags can separate the circumferential space in the barrel wall, a collecting assembly extending into the barrel wall is arranged on the outer wall of the base, and the collecting assembly can support and adjust the positions of the collecting bags. Compared with the prior art, the device has the advantages of uniform root division and accurate variable control of biological research, and can adapt to plants with different sizes and scales.

Description

technical field [0001] The invention relates to the technical field of biological analysis devices, in particular to a root splitting device for studying the influence of rhizosphere soil microorganisms on root exudates and a method for using the same. Background technique [0002] The activities of rhizosphere microorganisms play an active role in decomposing organic matter, releasing and storing nutrients in the rhizosphere nutrition of plants. The main reason why the rhizosphere can produce this special effect is that the plant root system continuously secretes various metabolites, which provide a continuous source of nutrients for the life activities of microorganisms. Introducing the research on the influence of rhizosphere soil microorganisms on root exudates into agricultural production plays an important role in creating a good rhizosphere ecological environment, reducing the use of chemical fertilizers and pesticides, and inhibiting the occurrence of pests and disea...
