摘要
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。
The experiments have been made by spraying uniconazole during the common wet growing seedlings,two-stage growing seedlings, growing seedlings in green house and dry growing seedlings respectively in 1997. Results showed that the tillering , chhorophyll content of leaves, root ability and the effective spike at later growing stage would increase by treatment with uniconazole of 100mg/L (during one leaf stage for wet growing seedlings), spraying with 100mg/L (during one leaf stage for tow-stage growing seedings and in green-house) and twice spraying 100mg/L in transplanting field respectively, howerer, stem height decreased. Compare with CK, its yield increaeed by 13.6%～19.6%, but it is not fit for the dry growing seedlings.
