Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree planting, in particular to a portable sampling device for fruit trees. Background Art

[0002] During the growth period and different growth stages of fruit trees, it is necessary to sample the soil around the rhizosphere of the fruit trees. The rhizosphere soil refers to the micro-domain soil that is directly affected by the plant roots, including the soil 1-2 mm away from the active roots and the root surface and the soil attached to it. It is relatively unique in the soil system and can reflect the activities of the soil, roots, and microorganisms. The study of the rhizosphere area has become an emerging marginal discipline in the field of plant nutrition today.

[0003] Existing sampling devices are usually cylinders with hollow bottoms, which need to be directly inserted into the soil for sampling operations. However, due to the high moisture content of the soil, the soil becomes sticky and adheres to the inner wall of the sampling device. Removal of the sampled soil is hindered by the stickiness of the soil, and the soil remaining in the device will have dead corners when cleaning. If it is not cleaned thoroughly, it will affect the next sampling operation. Utility Model Content
