As The tomato fruit's nutrition contents Vc,soluble solid matters,soluble sugar,free amino-acid and the ratio of sugar to acid were respectively 13.60μg.
The results showed that the soil chronically treated by straw organic fertilizer had good physical and chemic properties, the fertility in soil is higher, the enzyme activity is high with the microorganism vitality, the ratio of bacteria to fungi is stable and the general soil fertility is highest among three treatments in this experiment.
We can find the soil treated by organic manure has extensive nutrient and high fertility. The result of plant's growth and fruit quality indicated that the plants handled by straw organic fertilizer were stronger and highher with higher absorbency of roots and net photosynthetic rate.
