Description

Sampling device for leguminous plant D-shaped root nodules

Technical Field

The utility model relates to the technical field of botany, in particular to a leguminous plant D-shaped root nodule sampling device.

Background

The root nodule is a symbiotic nitrogen fixation structure formed by the root of the leguminous plant and rhizobia. Nodules are produced by the invasion of rhizobia, which live in the soil, into the roots. Rhizobia invades from root hair, exists in cortex parenchyma cells of roots, and on one hand, proliferates in cortex cells in a large quantity, and on the other hand, secretions stimulate the cortex cells to divide rapidly. The number of cells was significantly increased. Thus, the local volume of the cortex is enlarged and protruded, and a nodule-shaped protrusion, namely a nodule, is formed. The relationship of rhizobia and leguminous plants is a favorable symbiotic relationship with each other. On one hand, the rhizobia can absorb water and nutrients required by growth and development of the rhizobia from cortical cells of roots, and on the other hand, the rhizobia can fix free nitrogen in the air and convert the free nitrogen into ammonia for leguminous plants to utilize. The biological nitrogen fixation function improves the soil structure and the soil fertility, and is an ideal species for ecological restoration. The method has the advantages that the efficient and rapid collection of the legume root nodules is an important premise for researching the rhizobium population distribution and solitary efficiency of the legume symbiosis, and has important significance for fully exerting the inherent nitrogen fixation ecological effect and improving the soil fertility of a degraded ecosystem;

the conventional common method for collecting the root nodules is to remove litters and the like on the surface layer of soil by using a small shovel after finding target plants, and then lightly dig the litters and the like within a range of 15-20cm around a main root to find the root nodules. Due to the fact that leguminous plants are developed and the soil environment conditions are complex, the method consumes a large amount of time and labor when the leguminous plant root nodules in the natural ecosystem environment are collected. At present, no literature reports a standard and standardized method for efficiently and quickly collecting legume root nodules. Therefore, aiming at the defects of the existing sampling method, the method for rapidly, efficiently and reasonably collecting the legume root nodule is established, and is of great importance for the research of the legume root nodule bacteria.
