[目的]研究4种除草剂对谷子的敏感性及安全剂拌种的效果,为谷子田筛选高效、安全的禾本科杂草除草剂。[方法]采用温室大棚盆栽试验法。[结果]二氯丙烯酰胺0.1、0.8 g/kg及解草啶0.8 g/kg种子处理对33%二甲戊灵乳油药害有显著的缓解作用,解草胺0.1 g/kg、解草酯0.8 g/kg种子处理对50%丙草胺乳油药害缓解作用显著,二氯丙烯酰胺0.1 g/kg、解草酮0.1 g/kg、解草酯0.8 g/kg种子处理对80%莠去津可湿性粉剂药害有一定的缓解效果。[结论]谷子对二甲戊灵、精异丙甲草胺、丙草胺、莠去津4种除草剂均较为敏感,部分安全剂能够一定程度上缓解其对谷子的药害。
[Objective] The research aimed to study the sensitivity of mildew to four kinds of herbicides and the effect of safener seed dressing, and to screen the millet field for the efficient and safe gramineous weed herbicide. [Method] Pot experiment was conducted in greenhouse. [Result] The results showed that 0.1, 0.8 g / kg dichloroacetamide and 0.8 g / kg rhizomamine could remarkably relieve the injury of 33% pendimethalin EC. The herbicide 0.1 g / kg, 0.8 g / kg seed treatment of 50% methamphetamine EC significantly alleviate the role of the drug, dichloroacrylamide 0.1 g / kg, 0.1 g / kg of clover ketone, clove ester 0.8 g / kg seed treatment of 80% Tianjin WP poisoning can have some relief. [Conclusion] Millet was sensitive to four herbicides, pendimethalin, metolachlor, pretilachlor and atrazine. Some safeners could alleviate the harm to millet to some extent.
