Abstract

In order to investigate the effects of chemical fertilizer reduction on the growth and quality of tomato, the application of 100% chemical fertilizer, 10% chemical fertilizer reduction, 25% chemical fertilizer reduction and 35% chemical fertilizer reduction treatment were studied on the basis of organic fertilizer application. Changes in growth physiology quality and yield of tomato were studied. The results showed that, in the case of applying organic fertilizer, compared with traditional fertilization, the reduction of chemical fertilizer to 35% had no effect on the plant height, leaves’ nitrogen and chlorophyll contents. The contents of Vc and acidity of tomato were the highest when chemical fertilizer were reduced by 25% and 35%,the reduction of chemical fertilizer to 25% and 35% were significantly lower than that of chemical fertilizer of 100% and reduction of chemical fertilizer to 10% treatment on the content of Vc, and different chemical fertilizer application were not significantly on the acidity content. The nitrate content of tomato decreased with the cut down of fertilizer amount, and the chemical fertilizer reduction of 25% and 35% were significantly lower than that of chemical fertilizer reduction of 10% and chemical fertilizer application 100%.Tomato yield was increased by 0.77% and 1.42% compared with the control group by 10% and 25% reduction of chemical fertilizer, and tomato yield was reduced by 1.28% compared with the control group by 35% reduction of chemical fertilizer. The yield was no significant difference among different fertilization treatments.
