摘要
研究了不同时间施用除草安全剂奈安,对缓解湖南烟稻水旱轮作中水稻除草剂二氯喹啉酸残留的药害,结果表明:在烟草的农艺性状、生理生化指标、化学成分方面,施用奈安越早,烟草的恢复情况越理想,但最后施用奈安处理的烟草表现出较好的生长势,烟株生长恢复情况比其他处理略好,此时正处于烟草的生根期,因此奈安的最佳施用时间是烟草的生根期。
In order to reduce Quinclorac residue effectively,the test for Naian optimum application time was carried out here.The results showed that: for the agronomic characters,physiological and biochemical indexes,and chemical compositions,earlier Naian was applied,more ideally tobacco plants recovered.However,the tobacco plants in the treatment with latest Naian application showed better growth potential,and they recovered slightly better than others.Therefore,the rational application time of herbicide safener Naian was the rooting stage of tobacco.
