摘　　要：选择影响杂交水稻种子风筛精选中的3个主要因素,研究了各因素对杂交水稻种子精选质量的贡献。结果表明,在所选因素水平区间,上筛孔尺寸是杂交粳稻滇杂31获选率、杂交籼稻冈优827净度的重要影响因素,上筛孔尺寸与净度负相关,与获选率正相关;下筛孔尺寸不是净度的重要影响因素,却是获选率的重要影响因素且与之负相关;风速既不是净度也不是获选率的重要影响因素。Three main factors of air-and-screen processing of hybrid rice seeds were selected, the contribution of each factor to cleaning quality of hybrid rice seeds was studied. The results showed that in the selected range, upper sieve size was an important influencing factor to the elected rate of japonica hybrid rice Dianza 31 and the neatness of indica hybrid rice Gangyou 827, upper sieve size was negatively correlated with neatness and was positively correlated with neatness; lower sieve size was not an important influencing factor to neatness, but it was an important influencing factor to the elected rate and was positively correlated with it. Wind speed was not an important influencing factor to neatness or elected rate.
