在杂交水稻的常规湿润育秧、两段育秧、温室育秧和旱育秧中分别进行了喷施烯效唑试验。结果表明，在湿润育秧的１叶１心期喷施１００ｍｇ／Ｌ烯效唑，在两段育秧、温室育秧的１叶１心期和寄秧田两次喷施１００ｍｇ／Ｌ烯效唑，均能提高叶片的叶绿素含量，促根、增蘖、降低株高，生育后期有效穗增加。与对照比较，上述处理的增产幅度为１３．６％～１９．６％。旱育秧秧苗期不宜施用烯效唑。
Uniconazole test was carried out on conventional wetting and seedling cultivation, two-stage seedling raising, greenhouse seedling raising and dry seedling raising of hybrid rice. The results showed that 100mg / L uniconazole was sprayed in the first leaf and the second heart of the wet seedling, and 100mg / L uniconazole was sprayed in two leaf stages, Improve leaf chlorophyll content, promote root, increase tillering, reduce plant height, and increase effective panicle during later growth period. Compared with the control, the increase rate of the above treatment was 13.6% ~ 19.6%. Nursery seedling seedling stage should not be applied uniconazole.
