The author explored the productivity of rice variety Y Liangyou 2 through the tests for different nitrogen application levels and planting densities in the local area .The results showed that:under the middle soil fertility, when the nitrogen application rate was 180 kg/hm 2 , and the row spacing of plants was 30 cm ×21.6 cm, Y Liangyou 2 had the highest productivity, its yield reached 10521.62 kg/hm 2 , and its spike-grain structure was the optimal.Under these conditions, the peak seedlings could reach 2767700 hole/hm 2 , and 2536400 effective spikes per hectare could be ensured .
