摘　　要：采用盆栽试验和小区试验相结合的方法 ,对砂姜黑土上不同小麦品种的分蘖成穗特性及其调控进行了研究 .结果表明 ,兰考 90 6分蘖发生快、多且衰亡也最快 ,分蘖成穗率较低 ,主要是由于二、三级分蘖发生较多 ,越冬期具有 4张以上叶片的分蘖才能成穗 .温麦 6号分蘖发生平稳 ,成穗率最高 ;百农 64分蘖力中等 ,增加一定的施肥量能明显提高分蘖成穗率 .不同生长调节剂对兰考 90 6分蘖成穗有明显的调控作用 ,以 6 BAt和 2 ,4Regulations of wheat tillering were studied by pot and micro plot experiments. The results from Lankao 906 showed that the tillers with 4 leaves before the 20 of December could become productive tillers. Bainong 64 was better than Lankao 906 and Wenmai No. 6 was steady and the best in terms of the percentage of productive tillers. Several plant growth regulators such as 6 BA and 2,4 D could be used to improve tillering, especially for Lankao 906.
