摘要： Pig manure rice straw compost was extracted using different extraction methods, and the composition of each extraction was identified by chromatogram and spectroscopy in order to investigate plant growth promoting factors. Compared with direct extraction, aerated and non-aerated fermentation extractions were better for nutrient accumulation, especially for high molecular weight substances. Cucumber yields of aerated fermentation extraction of compost (AFEC) treatment were 16.5 and 57.6 % higher than the direct extraction of compost (DEC) and non-aerated fermentation extraction of compost (NAFEC) treatments. Humic acid-like and fulvic acid-like substances were the main components in all extracts. Furthermore, AFEC showed the most humification and aromatization. Humic substances extracted from AFEC (H-AFEC) increased shoot dry weight by 2.8 and 7.4 %, compared to humic substances extracted from DEC (H-DEC) and humic substances extracted from NAFEC (H-NAFEC). In conclusion, AFEC was the best extraction method to get more humic substances to stimulate plant growth.
