The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.

The result shows that: the extraction of petroleum ether, polysaccharide and sodium copper chlorophyllin from banana leaves perform higher spumescence ability and foam stability. The critical concentration form pastern namely CMC and the surface tension in this concentration are 1.0 g/l (34.295 mN/m), 1.0 g/l (42.398 mN/m), 3.0 g/l (40.123 mN/m) respectively, which the value is close or excess the reference samples. The emulsify capability of the extraction of petroleum ether is the best in these active ingredients, and close to the emulsify capability of Tween-80. The emulsify capability of polysaccharide and sodium copper chlorophyllin from banana leaves are follow then.

As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.
