Abstract

Study on the effects of different N,P,K combined application on yield of marigold,utilizing 3414 regression design,research the relationship between different N,P,K combined application and yield of fresh flowers.The results showed that N,P,K combined application would significantly increased the fresh flowers yield of marigold,the yield of each fertilizing treatment was increased 4 312.02 kg/hm2 to 12 471.92 kg/hm2 respectively.The optimal yield was 48 382.98 kg/hm2,which fertilizer rate was nitrogen fertilizer(N):169.68 kg/hm2,phosphate fertilizer(P2O5):111.16 kg/hm2,potassium fertilizer(K2O):67.13 kg/hm2,and the net income would increased 5 282.04 Yuan per hectare.
