Abstract: ’Fenhong 908’ was taken as material,the effect of different fertilizations on growth and quality of tomatos was studied.And it was treated by different fertilizations,10% reduction of chemical fertilizer（T1）,20%reduction of chemical fertilizer（T2）,10%reduction of chemical fertilize with organic fertilizer（T3）,20%reduction of chemical fertilizer with organic fertilizer（T4）,with the methods of random block experiment.It was meansured that plant height,the steam thickness and yield,nitrate,soluble sugar,soluble protein,vitamin C and organic acid content of tomato,to compare the effection of different fertilization on growth and quality of tomato.The results showed that 10%and 20%reduction of chemical fertilizer could decrease the growth of tomato,make the plant height and stem thickness lower than CK,yield and quality also lower than CK.Combination application of organic and inorganic fertilizers could stabilize the yield,improve the quality significantly,and the best treatment was the 20%reduction of chemical fertilizer with organic fertilizer.
