摘要:

在科尔沁少花蒺藜草入侵地区,为了筛选出适宜在此推广的少花蒺藜草化学防除药剂,以不同化学防除药剂及其组合为试材,采用野外调查和室内分析相结合的方法,测得不同药剂处理和喷施时间对少花蒺藜草的防除效果、相对防除效果和植被群落盖度影响的数据。结果表明:不同药剂处理和喷施时间对少花蒺藜草的防除效果、相对防除效果和植被群落盖度均有显著作用。对少花蒺藜草的防除效果和相对防除效果均最佳的药剂为41%草甘磷异丙胺盐,其次为10%精喹禾灵、10%精喹禾灵+90%乙草胺、12.5%烯禾啶和10.8%高效氟吡甲禾灵。然而,从植被群落盖度看,适宜选用的药剂有10%精喹禾灵、12.5%烯禾啶、5%咪唑乙烟酸、23.5%乙氧氟草醚和10.8%高效氟吡甲禾灵。综上所述,科尔沁地区适宜的少花蒺藜草化学防除药剂有10%精喹禾灵、12.5%烯禾啶和10.8%高效氟吡甲禾灵,且只需喷施一次即可达到较好效果。

Abstract:

In the invasion area of Cenchrus pauciflorus in Khorchin, in order to select the suitable chemical control herbicide in Khorchin area, different chemical control herbicides and combinations were used as test materials, the method combining field investigation with lab analysis was adopted to obtain the experimental data of the effects of different herbicide treatments and spraying time on control, relative control and vegetation coverage. The results showed the effects were significant. The optimal insecticide for the control and relative control on Cenchrus pauciflorus was 41% Glyphosate-Isopropylammonium, followed by 10% quizalofop-p-ethyl, 10% quizalofop-p-ethyl mixed with 90% acetochlor, 12.5% sethoxydim and 10.8% haloxytop-r-methyl. However, in view of vegetation coverage, the suitable herbicides were 10% quizalofop-p-ethyl, 12.5% sethoxydim, 5% imazethapyr, 23.5% sethoxydim and 10.8% haloxytop-r-methyl. In conclusion, the appropriate chemical control herbicides include 10% quizalofop-p-ethyl, 12.5% sethoxydim and 10.8% haloxytop-r-methyl in Khorchin, and only spraying once could obtain better effects.
