| 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。

| Abstract: | 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-tive>Aspergillus 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 g>biological additive>Aspergillus 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. |
