摘要
应用化学除草剂对毒草大戟E.lamprocaypaprokm进行了防除试验,结果表明,在大戟营养生长期(即抽茎期)用72%的2、4-d丁酯乳油剂量0.75L+300kg/ha进行喷雾,防效率可达96.23%,能够有效地灭除毒害草大戟,达到改良退化草地,提高草地产量和质量的目的。
The result of test for killing E.lamproeaypaprokm chemical herbicine shows that spraying 0,75L+ 300kg/ha, 4-D butylate (72%) will kill 96.23% of E.lamprocaypaprokm during its growth period.
