Abstract: This study is to explore the effects of organic fertilizer and biostimulants on soil microorganisms, plant growth and yield, and to provide the improved fertilization scheme for plant growth. Using tomato （Solanum lycopersicum） as experimental materials, the effects of different fertilization treatments were investigated by a randomized block experiment. Four treatments were set up, including control, 0.1% biostimulant, Fubang 5% organic fertilizer and Fubang 5% organic fertilizer plus 0.1% biostimulant. The changes of soil microorganisms, the plants growth and the yield of tomato in each experimental plot were recorded, and their differences were statistically analyzed. The results showed that quantity of fungi, bacteria and actinomycetes in soil were significantly increased by applying 5% organic fertilizer plus 0.1% biostimulant, and the plants growth and the yield of tomato were significantly higher than those of the other three treatments. In clude, the fertilization scheme, 5% organic fertilizer plus 0.1% biostimulant, can significantly enhance soil beneficial microbial population, promote plant growth and improve vegetable yield and quality.
