Effects of deeply mechanized fertilizer application on the quality and grain yield of direct seedling rice were studied using super hybrid rice Peizataifeng and super inbred rice Yuxiangyouzhan as samples in field trials.The results showed that grain yields were increased significantly when the increase of rice special fertilizer rate ranged from 0 to 1 500 kg/hm2.The number of effective panicle per m2 and solid grain per panicle were increased.More application of rice special fertilizer would increase plant height,index of leaf area,SPAD in sword leaf at late stage,and total dry mass weight of rice.The results indicated that deeply mechanized fertilizer application can improve quality of rice significantly.
