Effects of Combined Application of Mineral Organic Fertilizer and Reduced Application of Chemical Fertilizer on Celery Yield

We conducted the field trial to investigate the effects of combined application of mineral organic fertilizer and chemical fertilizer on the quality and yield of celery by using single factor test design.The results showed that,under the condition of combined application of mineral organic fertilizer,the quality and yield of celery were significantly improved,and the yields were 9 948.6,9 610.5 kg/667 m2when the application amounts were reduced by 10% and 20%.There was no significant difference between the yields of the local optimum chemical fertilizer treatment and the treatment reduced 20% chemical fertilizer with combined application of mineral organic fertilizer,indicating it was feasible to reduce the current optimum application amount of chemical fertilizers by 20% with combined application of mineral organic fertilizer reasonable.
