Abstract: To investigate the effects of organic and inorganic fertilizers on the yield and quality of pepper and tomato.Under the greenhouse cultivation condition,the pepper and tomato of field experiments were conducted to study the effect of yield and quality when reduced organic and inorganic fertilizers and combined the both application.The treatments were set up as no fertilizer,100% organic fertilizer,75% organic fertilizer,50% organic fertilizer,50% chemical fertilizer+50% organic manure fertilizer,75% chemical fertilizer,50% chemical fertilizer.The results showed that reduction and combined application of chemical and organic fertilizer had no significant effect on the yield of pepper, the effect of soluble solids content, soluble sugar content and soluble protein content was relatively small.The treatment that combined application of chemical and organic fertilizer and the quality of pepper which the content of nitrate was the lowest and the content of vitamin C was highest.While reduced the fertilizer application would lead to a different degree of yield increase for tomato, and compared with other treatments,treatment of 50% chemical fertilizer+50% organic manure fertilizer reached the highest yield and the best quality which the nitrate content of tomato was the lowest, and the content of vitamin C and amino acid were the highest, and the difference of soluble solids content and sugar acid ratio was relatively small.
