摘要
采用混配方法系统研究了假苍耳的化学防除。结果表明,草甘膦对假苍耳有较好的防除作用,加入助剂能够提高草甘膦对假苍耳的防效,生助>黑助>(NH4)2SO45g>(NH4)2SO41g>对照,生助增效最大,最大株防效为98.03%～99.28%,最佳防除时期为4～6叶期;氟磺胺草醚对假苍耳有较好的防除作用,加入助剂能够提高氟磺胺草醚对假苍耳的防效,(NH4)2SO45g>(NH4)2SO41g>生助>黑助>对照,其中(NH4)2SO45g增效最大,最大株防效为95.15%～97.19%,最佳防除时期为4～6叶期。
Analyzed with mix methods, the article studied chemical control of Iva xanthifolia sys-tematicly. The results of Iva xanthifolia＇s chemical control showed that glyphosate could control Iva xanthifolia effectively, by adding additive to improve glyphosate＇s pharmacodynamics, biological addi-tiveAspergillus niger additive〉（NH4） 2SO4 5 g〉（NH4）2SO4 1 g〉CK. Biological additive could increase the control effectively, the biggest control effect was 98.03%-99.28%. 4-6 leaves time was the best control time; Fomesafen could control Iva xanthifolia effectively, by adding additive to improve fomesafen＇s pharmacodynamics, （NH4）2SO4 1 gbiological additiveAspergillus niger additive〉CK, （NH4）2SO4 5 g could maximally increase the control effect, the biggest control effect was 95.15%-97. 19%. 4-6 leaves time was the best control time.
