摘要
通过田间试验,研究了不同玉米品种对二氯喹啉酸的敏感性差异。供试玉米品种对二氯喹啉酸的敏感性顺序为:垦粘一号>东农早粘>东农888>东农248>东农9701,特用玉米比普通玉米敏感。玉米四叶一心至五叶一心期施用二氯喹啉酸,东农9701的安全用量为900ga.i /hm2,东农248与特用玉米的安全用量为600ga.i /hm2。
A field experiment was carried out to evaluate the sensitivity of quinclorac in different corn cultivars. The sequence of sensitivity of quinclorac to offered corn cultivars was KN-Yihao>DN-Zaonian>DN-888>DN-248>DN-9701. The special corn cultivars were more sensitive than common corn ones. When corn was 4.5 to 5.5 leaves, the safe dosage of quinclorac was 900g a.i./hm^2 in DN-9701 and 600g a.i./hm2 in DN-248 and special corn cultivars.
