摘要
通过对Y两优2号进行不同氮素水平和栽插密度试验探讨该品种在本地区生产力,结果表明:在土壤肥力中等的条件下,施氮量180 kg/hm2,栽插行株距为30 cm×21.6 cm条件下,Y两优2号在该地区生产力最高,产量可达10521.62 kg/hm2,并且穗粒结构最佳,在此条件下Y两优2号高峰苗可达到276.77万穴/hm2,同时保证有效穗数为253.64万穴/hm2。
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 .
