Abstract

This paper described the influence of different fertilizers on tomato planted in protected soil . The results showed that biological organic-inorganic compound fertilizer expressed quite important effects on yield, quality of tomato and soil nutrient. Compared with the NPK chemical compound fertilizer and control, the yield, soluble sugar content, organic acid content, and VC content in tomato were increased 7.34%～13.64%, 18.2%～23.2%, 8.3%～15.6%, 13.2%～15.1% respectively , while the nitrate content of tomato were reduced 22.9%～23.8%. The content of organic matter, alkaline N, available P, available K in tested soil were increased by 8.25%～10.48%, 9.43%～14.71%, 11.29%～15.00%, 13.60%～18.34% respectively; the number of bacteria, actinomycetes, and fungi were increased by 45.45%～60.00%, 14.29%～33.33%, 44.19%～100.00%.
