Description

Technical Field

[0001] The utility model belongs to the technical field of nodule collection, and in particular relates to a leguminous plant nodule sampling device. Background Art

[0002] Rhizobia are a type of Gram-negative bacteria that can symbiotically form nodules with legumes and reduce nitrogen in the air into ammonia for plant nutrition. Rhizobia mainly refer to bacteria that symbiotically form nodules with the roots of legumes and can fix nitrogen, generally referring to the genera Rhizobium and Bradyrhizobium; both genera belong to the Rhizobiales order.

[0003] When collecting plant nodules, they are usually collected by hand or with clamps such as tweezers. Regardless of the collection method, a certain amount of pressure will be applied to the nodules, which may be damaged during the collection process. If a knife is used for cutting and collection, the cut nodules may be incomplete. In order to solve the above problems, a leguminous plant nodule sampling device is now provided.
