Abstract
In this experiment, applying the anchor-shank tensiometer and Shearing box designed by oneself had been carried on In-situ measurement to test the fixing capability of soil of the root system of bristlegrass in the depth of 10cm and 20cm. The results show:In 10cm depth, when increasing 4.9KN in load exerted, the displacement of the Faber bristlegrass sampled soil square is 53.3mm, whereas biggest loads of sampled soil square bears 4.4KN and the displacement reached 55.0mm under this load. In 20cm depth, when increasing 5.3KN in load exerted, the displacement of Faber bristlegrass sampled soil square is 53.7mm, however biggest loads of sampled soil square bears 4.0KN. The In-situ measurement would appraise different crops (plants) fixing capability of soil in water and soil conservation as an effective means.
