The test according to the characteristics of organic fertilizer, for a pot experiment, Harmless disposal of manure straw bio-organic fertilizer dosage of variable factors, research, analysis of tomato special fertilizer application rate on potted tomato plant growth, quality, soil nutrients through organic manure application on soil available and total nutrient and the impact of micro-organisms. Draw the following main conclusions:1.The quality of organic fertilizer is12000kg/ha, tomatoes growing higher than the application rate, tomato quality traits than other fertilization the amount of organic manure and chemical fertilizer handle better, the best application rate of organic fertilizer is12000kg/ha.2.The application of organic fertilizer processing, with the increase of the amount of fertilizer, tomato production and the corresponding increase. When fertilization12t/ha, each of ha higher yield than the other fertilizer levels.3.With the bio-organic fertilizer was applied the number of bacteria and actinomycetes growth, the increase in the number of fungi is not obvious, we know that the tomato special fertilizer fertilizer play role in the formation of the beneficial role of microorganisms, it is conducive to the growth and development of tomato.4.Application in tomato special fertilizer can increase soil available N, P, K content, tomato special fertilizer can increase the content of the soil microbial and microbial biomass carbon content. with the increase of application rate, the content enhance. Fertilization capacity of12000kg/ha and16000kg/ha for the better of the two bio-organic fertilizer processing.5.When the application rate of12t/ha, the highest vitamin C and reducing sugar content, vitamin C and reducing sugar content began to decrease when the application rate continues to increase.6. Tomato special fertilizer on soil enzyme activity in performance:1) When the application amount of8000kg/ha, soil invertase activity in the highest.2) When the application rate of12000kg/ha, soil urease and catalase, polyphenol oxidase, acid phosphatase activity than the rest of fertilizer treatment.3) soil fertilizer processing protease activity was significantly less than the organic fertilizer treatment. Therefore, the application rate of12,000kg/ha, increase activity in the soil, excessive application can actually reduce the activity of these enzymes in the soil.In summary, considering the impact of organic fertilizer on the quality of tomatoes, the most appropriate to the12t/ha.
