摘　　要：为提高杂交油菜黔油30号撒播高产栽培提供依据,采用随机区组设计研究蕾薹期氮磷钾三元复合肥施用量对其产量的影响。结果表明:蕾薹期追施复合肥对黔油30号撒播产量的影响极显著;黔油30号撒播栽培最佳的施肥方式为播种前施三元复合肥(15-15-15)15.00 kg/667m^2,苗期追施纯氮6.50kg/667m^2的前提下,蕾薹期施三元复合肥46.67kg/667m^2。在此施肥条件下,撒播黔油30号500g/667m^2,其产量为194.00kg/667m^2,株高161.30cm,一次有效分枝数3.8个,单株有效角103.7个,每角粒数16.3粒,千粒重4.4g。To provide the basis for high-yield cultivation of hybrid rape variety Qianyou 30 with broadcast cultivation,a randomized block design was employed to explore the effects of application amount of compound fertilizer in bolting stage on the yield.Results：Topdressing compound fertilizer in bolting stage had extremely significant influence on Qianyou 30 with broadcast cultivation;The best fertilizer application mode for broadcast cultivation of Qianyou 30 is that 15 kg compound fertilizer（15-15-15）used as base fertilizer,6.5kg N used in seedling stage and 46.67 kg compound fertilizer used in bolting stage.Then the yield,plant high,number of effective branches,seed number per pod and thousand seeds weight reached 194.00kg/667m^2,161.30 cm,3.8branches,103.7pods,16.3grains and 4.4g respectively.
