The soil in coal mining subsidence areas in the arid and semi-arid regions of western China is poor and plant growth is restricted.In order to investigate the effects of urban sludge compost and microbial fungicides on the growth and soil nutrients of Astragalus adsurgens in semi-arid coal mining areas，urban sludge compost and three microbial fungicides were used as soil conditioners to study their application effects on soil nutrients and growth of Astragalus adsurgens，as well as resistance to adversity.The results showed that sludge compost with three microbial fungicides(WPBK group) increased soil nutrient contents such as soil humus，total nitrogen，alkaline dissolved nitrogen，available phosphorus，available potassium and other soil nutrient contents，and also improved the growth indexes such as plant height and root length of Astragalus adsurgens，and enhanced the resistance ability of Astragalus adsurgens.Under the conditions of the field experiment，the WPBK group had the best overall effect.Compared with CK，the average contents of soil humus，total nitrogen，available phosphorus，and available potassium significantly increased by 90.6%，28.66%，130.81%，and 32.55%，respectively；the average contents chlorophyll a，chlorophyll b and carotenoids of Astragalus adsurgens were significantly increased by 70.80%，71.43%，and 59.18%，respectively；the plant height，root length and cover of Astragalus adsurgens were significantly increased by 81.5%，155.45% and 210%，respectively；the above and below ground biomass of Astragalus adsurgens significantly increased by 140.38% and 208.27%，respectively；the average contents of proline，SOD，CAT and POD of Astragalus adsurgens were significantly increased by 102.16%，139.20%，466.66% and 93.96%，respectively.Overall，the WPBK group had the best effect，in addition，the WP group also had good effect in the promotion of growth and soil nutrient enhancement of Astragalus adsurgens，but the effect on plant resistance was average.This study provided technical supports for vegetation restoration in arid and semi-arid mining areas and provided a basis for the effective use of sewage plant sludge compost in vegetation restoration in mining areas.
