Description

Technical Field

[0001] The utility model relates to the technical field of soil moisture detection, in particular to a walnut planting soil moisture detection sampling device. Background Art

[0002] Soil moisture is a very important variable in studying terrestrial water cycle and energy cycle. The data related to soil quality obtained from soil moisture detection is crucial for agricultural production. In the process of walnut planting, it is necessary to control the moisture of each layer of the soil to create the best growth environment for walnuts, improve its yield and increase benefits. Soil sampling is required before testing. Existing soil sampling devices are mostly desktop and equipped with a fixed base. The sampling tube is inserted into the ground for sampling through a motor and an electric push rod. The overall volume is large and cannot be carried by one person. It is difficult to move. In addition, the walnut planting area is all muddy and has a low flatness, which makes the sampling device more time-consuming when performing multi-point sampling, affecting the sampling efficiency. At the same time, the sampling tube is mostly an integrated design with a long length. It is more laborious to squeeze out the soil inside and the extruded soil is easily mixed, affecting the accuracy of stratified detection. Utility Model Content
