摘　　要：以秋芝麻是否施蕾花肥为主处理 ,以种植方式为副处理的 2× 2裂区试验 ,观察各裂区初花期至全部植株开花的开花株率动态。结果表明 ,施蕾花肥比不施蕾花肥初花期提早近 2d ,进入盛花期早 1d ,增产 5.1 % ,产量差异未达显著水平 ;宽窄行密株比一穴双株初花期落后 1d ,但开花株率增长速度快 6 .3 %～ 2 5.6 % ,进入盛花期反而早 1d ,最终增产 2 8.9% ,产量差异达显著水平。The test was carried out by split plot design with nitrogenous fertilizer distributions as main treatment and planting patterns as minor one ,to observe the increased flowering rate of autumn sesame per split plot from early blooming stage to final flowering stage Results showed that:N application in flower bud period made autumn sesame two days earlier into bloom and one day earlier into full bloom stage compared with the contrast ,and its yield increased by 5.1% with no significant difference .Compared with double seedlings per hole planting pattern , wide narrow row pattern started to flower one day later but get into full bloom stage one day earlier with flowering rate 6.3%～25.6% higher ,and its yield significantly increased by 28.9%.
