Description

technical field [0001] The invention relates to a root-soil root system friction measurement device, which belongs to the technical field of plant root system friction measurement. Background technique [0002] Plant roots have a good soil-fixing effect. In recent years, with the development of soil and water conservation technology, research on plant roots has become more in-depth, and the measurement of root friction is also particularly important. However, the existing friction measurement devices generally adopt the direct measurement method of the tension meter, and the human interference factors are relatively large, and the experimental data cannot be accurately recorded, which will cause a large measurement error. Therefore, it is necessary to provide a root-soil root system friction measurement device. to make up for these shortcomings. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provide...
