The cellulose-degrading strain n3 is deposited at the China General Microbiological Culture Collection Center (CGMCC) with a deposition number of CGMCC No. 18613. The cellulosedegrading strain n3 of the present disclosure can produce a high content of IAA which can reach 19.07 mg/L and carboxymethyl cellulose (CMC) enzyme whose activity can reach 24.96 U/mL. Therefore, the cellulose-degrading strain n3 can be used to prepare an IAA and/or CMC enzyme producing bacterial agent or a growth-promoting and straw-degrading bacterial agent for use in promoting straw degradation and crop growth to increase efficiency of the recycling and application of straw and crop yield.

The lateral isobaric triaxial experiment is carried out on a downhole drilling core to 5 simulate tectonic movement in the diagenetic evolution process of shale. Two standard column samples are taken in the same direction from the full—diameter core. One is taken as the control group. The other core is used as an experimental group j11 a triaxial mechanical experiment. In accordance with maximum primary stress 10 value in the Indosinian period, the confining pressure value should be determined. The triaxial experiment of core is carried out in the experimental group. A total of 7 rock samples (#Sl-#S7) are taken for SEM experiment after the triaxial experiment. The Image J software is applied to identify the microstructure l5 characteristics of shale (size, shape, direction and distribution of the grains and pore) in the stitched, image. The structure oriented entropy model is applied to calculate the grain arrangement. Then, the impact of the tectonic force on the shale microstructure can be determined. 20 (+ Fig. l)
