Rice quality is decided by genotype,environ-ment,and cultivation.We studied the effectson rice yield and quality by applying N fertiliz-er at late growth stage. Materials used were Peiza-maoxuan,alate binary hybrid rice.It was seeded on Jun16 and transplanted on Jul 19,1998,with aspace of 25.0cm×13.3cm,30hills/m~2 and 2seedlings/hill.The treatments were T1=1+2+3,T2=1+2,T3=1+3,T4=2+3,T5=1,and T6=CK(1:Applied N at boot-ing stage,2:Applied N at initiation stage,and 3:Applied N at grain filling stage).Theamount of N fertilization was 50g/plot·time Rice quality is decided by genotype, environ-ment, and cultivation.
