Experimental results of plant growth, and physical and mechanical tests of soil samples under different rock fragment contents

Plant growth monitoring, physical and in-situ mechanical shear tests were carried out at the test site field of Maoxian County, Sichuan Province, China. This dataset includes: 1. Thrust force-displacement initial data of both unplanted and B. brachycarpa soil samples obtained by the in-situ horizontal extrusion shear tests under different rock fragment contents, from which Fig. 4(c) is drawn. 2. Grain size accumulation of all samples obtained by SALD-3001 laser diffraction particle analyzer (less than 1mm) and sieving (larger than 1mm), from which Fig. 3(e) is drawn. 3. Parameters of plant growth under different RFCs to draw Figs. 3(a) and (b).
