进行5%烯效唑20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg浸种和喷施秧苗试验,研究烯效唑对水稻生长的影响,结果表明：5%烯效唑20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg浸种与对照药剂对比,发芽率提高0.4%～8.1%、出苗率提高2.7%～5.7%;烯效唑浸种和秧苗喷施处理后,水稻植株矮化,基茎宽、叶片宽、单株白根数增加,分蘖提早2～4 d,多蘖,田间有效穗增加,产量增加,效果优于目前常用的多效唑。生产上推荐使用浓度以30～40 mg/kg为宜。
進行5%烯效唑20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg浸種和噴施秧苗試驗,研究烯效唑對水稻生長的影響,結果錶明：5%烯效唑20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg浸種與對照藥劑對比,髮芽率提高0.4%～8.1%、齣苗率提高2.7%～5.7%;烯效唑浸種和秧苗噴施處理後,水稻植株矮化,基莖寬、葉片寬、單株白根數增加,分蘗提早2～4 d,多蘗,田間有效穗增加,產量增加,效果優于目前常用的多效唑。生產上推薦使用濃度以30～40 mg/kg為宜。
진행5%희효서20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg침충화분시앙묘시험,연구희효서대수도생장적영향,결과표명：5%희효서20 mg/kg、30 mg/kg、40 mg/kg、50 mg/kg침충여대조약제대비,발아솔제고0.4%～8.1%、출묘솔제고2.7%～5.7%;희효서침충화앙묘분시처리후,수도식주왜화,기경관、협편관、단주백근수증가,분얼제조2～4 d,다얼,전간유효수증가,산량증가,효과우우목전상용적다효서。생산상추천사용농도이30～40 mg/kg위의。
In order to study the effects of uniconazole on the rice growth,an efficiency test of uniconazole used for rice seed soaking and seedling spraying in proportion of 20 mg/kg,30 mg/kg,40 mg/kg,50 mg/kg with 5% uniconazole was carried out.The results showed that,germination and emergence rate was improved by 0.4%~8.1% and 2.7%~5.7%,respevtively to compare with control when soaking seeds in proportion of 20 mg/kg,30 mg/kg,40 mg/kg,50 mg/kg with 5% uniconazole;the rice grew better by using uniconazole to soak seeds or spray seedlings than by using paclobutrazol,showing dwarfing of stalk,wide base stem,wide leaves,increased white root per plant,earlier tillering stage by 2~4 d,more tillers,increased effective panicles per plant and yield.The proportion of 30~40 mg/kg with 5% uniconazole was recommended in the productive practice.
