Influence of Slow-release Formula Fertilizer on Yield,Quality and Efficiency of Processing Tomato

Taking ‘Tunhe No.8'processing tomato as material,compared with conventional fertilizer objective,the effect of the formula fertilization and slow-release formula fertilization and its reduction,nitrogen and phosphorus deficiency treatment on yield,quality and fertilizer efficiency of tomato were studied,in order to clear the scientific and the application processing tomato fertilizer formula,to provide a reference for application of slow release formula fertilization. The results showed under the same cultivation conditions,slow-release formula fertilization and its 20% decrement treatment promoted the growth of the processing tomato plants,the uptake of nitrogen and phosphorus plant were increased,the yield were increased by 4.12%and 7.86%than conventional fertilization,net income increased by 4.67% and 8.71%,while increasing the lycopene content and soluble solids content in fruit,under the condition of adding NAM, the dosage of nitrogen in the formula fertilization should reduce.
