摘要/Abstract

摘要： 本文用油菜(Brassica napus L.)根长法对NK#94827进行了生物活性筛选，结果表明，NK#94827对油菜的生物活性与氯磺隆和甲磺隆基本相当。室内土壤处理测定结果表明，NK#94827对稗草(Echinochloa phyllopogon (staf) Koss.)的除草活性比氯磺隆低，对苋菜(Acalypha australis L.)的除草活性与氯磺隆相当；NK#94827对玉米(Zea mayz L.)生长的抑制作用比氯磺隆和苯磺隆小，比甲酰胺磺隆大。温室盆栽试验结果表明，NK#94827以15g/hm2和30g/hm2进行土壤处理和茎叶处理时对小麦(Triticum, aestivum L.)和水稻(Oryza sativa L.)安全，各种剂量都对大豆(Glycine max)、燕麦(Avena sativa L.)和油菜的生长产生不同程度的药害。

Abstract: Herbicide acticity of new sulfonylurea herbicide NK#94827 was screened by bioassay of tap root of Brassica napus L., the results indicated that, the herbicide activity of NK#94827 was equal to that of chlorsulfuron and tribenuron-methyl. Furthere study by siol treatment in laboratory revealed that, NK#94827 possessed good herbicide activity to Acalypha australis L. and Echinochloa phyllopogon (staf) Koss. Maize growth inhibition of NK#94827 was lower than that of chlorsulfuron and tribenuron-methyl, however, it was greater than that of foramsulfuron. The results of pot bioassay in greenhouse indicated that, Triticum, aestivum L. and Oryza sativa L. were safe to NK#94827 at application dosage of 15g/hm2 and 30g/hm2 of soil treatment and foliage spraying, while phototoxicity to Glycine max, Avena sativa L. and Brassica napus L. was observed in all treatments of this study.
