Abstract

Effect of nitrogen amounts on growth characters and yield of Fuyou 33 were explored by plot comparative test,the result indicated that increasing nitrogen amounts can increase the effective panicles per unit area,LAI in full heeding stage,photosynthetic rate of flag leaf and dry weight accumulation of maturity.Then,increasing nitrogen amounts against productive panicle rate,high-efficiency leaf area rate and effective leaf area rate of full heading stage,the rate that dry matter accumulation in the grains yield after heading and harvest index.Under the test,treatment E3 which using N 240.0 kg/hm2 can achieve 9.22 t/hm2,it increase yield 0.2%、3.1%、3.4% and 7.3% than E4,E2,E5 and E1.
