Abstract:

On the gray desert soil of Xinjiang cultivation,planting film with drip irrigation ways processed on planting tomatoes,using conventional habits fertilizer as CK,the effect of different content and application method of potassium on yield and quality of processing tomato were studied.The results showed that increasing potash fertilizer could improve the fruit number per plant,the single fruit weight and yield of the processing.The number of the fruit number per plant was the main factor of yield increasing.The yield of K quantity with 150 kg/hm² (50% base,50% flowering period,drip into the three times) treatment was the highest,reached 15 t/hm².It increased 14.4% than control (no potassium).K quantity of 75 kg/hm² (50% base,50% flowering period,drip into the three times) the ratio of outputs to inputs of fertilizer was higher.But the ratio of potash was easily influenced by price changes.Potassium had significant influence on soluble solids content,viscosity,color distortions and the total acid content of processing tomatoes.In terms of comprehensive performance,under the condition of the membrane drip irrigation in Xinjiang,applying appropriate recommended processing tomato potassium chloride content in the range：75~150 kg/hm².The method of potash fertilization points as basal and topdressing
