摘　　要：对优质杂交香稻黔香优302进行了不同播期和不同施肥量的裂区栽培试验。结果表明:不同的追肥量(施尿素5 kg/667m2、10 kg/667m2和15 kg/667m2)间差异不显著;在中等基肥和栽插基本苗2.4万株/667m2的条件下,4月15日播种的处理平均产量616.3 kg/667m2,比4月5日和4月25日播种处理的平均产量增产极显著。4月15日播种,施追肥尿素15 kg/667m2,叶面喷施磷酸二氢钾作壮籽肥栽培处理,最高可获得638 kg/667m2产量。Qianxiangyou 302, a hybrid rice variety, was tested to investigate effects of different sowing time and nitrogen application amount on its yield. The results show that there is no significant difference among different amount of top dressing （5 kg/667m^2 , 10 kg/667m^2 and 15 kg/667m^2）, the average yield of Qianxiangyou 302 sowing on 15, April is 616.3 kg/667m^2 under the mlddle basic fertilizer and 24 thousand plant/667m^2 of density, significantly higher than the average yields sowing on 5,April and 25, April, and the yield sowing on 15, April can be up to 638 kg/667m^2 by applying 15 kg/667m^2 of urea as top dressing and 15 kg/667m^2 of KH2 PO4 as foliage dressing.
