And it was more significant to achieve higher yields by increasing grain number per spike than by enhancing spike number per unit area.
通过增加穗粒数来实现高产比增加单位面积穗数意义更大。

The results indicated that the grain per spike, seed setting rate, spikes per unit area and thousand grain weight had great contribution to the yield, especially grain per spike and seed setting rate.
结果表明：每穗粒数、结实率、单位面积穗数与千粒重对优质稻产量形成贡献较大，尤其是每穗粒数、结实率；
