Description

Rhizosphere soil sampling device

Technical Field

The utility model relates to the technical field of soil collection, in particular to a rhizosphere soil sampling device.

Background

Rhizosphere is a complex interface formed by plant root system-soil, and is an active micro-domain for exchanging nutrients between the underground part of plant and the external environment. The growth and development of root system and metabolism directly affect the physical and chemical properties of rhizosphere soil, so as to change the biological properties of rhizosphere soil with soil microbial activity and community structure as main characteristics. Rhizosphere soil, which centers on plant root systems, is more responsive to the external environment than non-rhizosphere soil. At present, research on plant-soil-microorganism interactions has attracted extensive attention from a large number of scholars, and one of the keys to develop related research is the collection of rhizosphere soil samples. The rhizosphere soil is collected by a root shaking method, the soil which is manually and gently shaken off is non-rhizosphere soil, the soil which is loosely adhered to the surface of the root system within the range of 1mm-4mm is rhizosphere soil, and finally the soil is brushed off by a brush. In the traditional collection process, the method needs manual operation by a worker, is laborious, and in the root shaking process, rhizosphere soil is easy to scatter, so that the actually collected rhizosphere soil is less, the environment is polluted, and the soil sample is wasted.

The patent of the utility model with the publication number of CN215640286U discloses soybean rhizosphere soil collection equipment, which comprises a soil containing mechanism and a soil sampling mechanism, wherein the soil sampling mechanism comprises a box body, a soil sweeping roller, a motor, a rotating shaft, a guide rod, a limiting plate and a spring, the root of a soybean seedling is clamped in the box body when the soybean rhizosphere soil collection equipment is used, then, the motor is started, the output end of the motor drives the rotating shaft to rotate, the soil sweeping roller is further rotated, the soil attached to the root of the soybean seedling is swept while the soil sweeping roller rotates, finally, the soil swept from the root of the soybean seedling falls into a lower cylinder body through a strip-shaped hole, the lower cylinder body is taken down from an upper cylinder body, so that a soybean rhizosphere soil sample can be obtained, a collection mode of a manual root shaking method is replaced, manpower is saved, a phenomenon of soil dispersion caused by the root shaking method is avoided, and a phenomenon of soil sample waste is reduced. However, the soybean seedling cleaning machine has the defects that the soil attached to the root of the soybean seedling is cleaned through the soil cleaning roller, the non-rhizosphere soil and the rhizosphere soil cannot be distinguished, and if the non-rhizosphere soil is manually shaken off before the soybean seedling cleaning machine is used, the soil can be scattered, and the environment is polluted.
