- 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900 g a .i./hm2 , 东农248 与特用玉米的安全用量为600 g a .i./hm2 。
- Abstract:
- A field experiment was carried out to evaluate the sensitivity of quinclorac in dif ferent co rn cultivars .The sequence of sensitivity of quinclorac to offered corn cultivars w as KN -Yihao >DN - Zaonian >DN -888 >DN -248 >DN -9701 .The special corn cultivars were mo re sensitive than common corn ones .When co rn w as 4 .5 to 5 .5 leaves , the safe dosage of quinclorac was 900g a .i ./ hm2 in DN -9701 and 600g a .i ./hm2 in DN -248 and special corn cultivars .
