| 摘 要： | 通过盆栽试验,探讨丙草胺施药量、施药时期、施药时水层深度对水稻的株高、分蘖影响。试验结果表明：有效剂量小于525 g（a.i.）.hm^-2的丙草胺对水稻的株高、分蘖影响不显著,用量高于600 g（a.i.）.hm^-2时株高明显受抑制,延迟分蘖发生的时间。

| Abstract: | The effect of pretilachlor using amount,applying period and water depth on plant height and tiller was discussed by basin culture. The results indicated.. When effective dosage lower than 525g a. i · hm^-2 , the effect of pretilachlor on plant height and tiller was un-remarkable, when higher than 600g a. i. hm^-2, rice plant was suppressed obviously, as well as delaying tiller occurrence. |
