1)Applied phenolic acids which were contained in upland rice crops were p-coumaric acid, ferulic acid, p-hydroxybenzoic acid vanillic acid. These phenolic acids made use of reagents which were neutralized by potassium hydroxide solution. 2)The application of phenolic acids caused soil microorganisms to grow rapidly. At 25℃ culture, the growth of soil microorganism finished in about 75 h. 3)The application of phenolic acids caused an increase in the numbers of fungi and bacteria, especially fungi which increased from 10 to 38 times that of non-applied soil. 4)Species of fungi were Penicillium, Fusarium, Aspergillus, Trichoderma, etc. The dominant species of fungi was Penicillium and it occupied 60% of total fungi. By the application of p-coumaric acid and p-hydroxybenzoic acid, the ratio of Penicillium to the total fungi rose to above 85%.
