【摘要】:以醉马草(Achnatherum inebrians)严重发生区域为研究对象,探究物理、化学和生物方法对醉马草的防控效果,以期获得适宜的防控方法。结果表明:不同防控方法在防控当年就对醉马草种群高度、盖度、密度和地上生物量表现为一定的抑制作用;对可食牧草盖度、密度,群落多样性指数、均匀度指数表现出一定程度的促进作用。综合评价其防控效果,使用10%浓度草甘膦+皂粉(点喷)(H2)对醉马草的防除效果较好;建议在醉马草零星分布区采用人工拔除(W1),成片分布区采用高频刈割(W2);若想建立有益植物群落,则可直接补播补紫花苜蓿(Medicago sativa)+无芒雀麦(Bromus inermis)+紫羊茅(Festuca vubra)(1∶1.5∶1)(S2);化学和物理防控后,也可辅助补播,以稳定防控效果。
[Abstract]:In order to obtain the appropriate control methods, this paper studies the effect of physical, chemical and biological methods on the prevention and control of (Achnatherum inebrians). The results showed that the different control methods inhibited the population height, coverage, density and aboveground biomass in the year of control, and showed certain inhibition on the coverage, density and community diversity index of edible forage. Evenness index shows a certain degree of promotion. Comprehensive evaluation of its control effect, the use of 10% glyphosate soap powder (point spray) (H2) on the prevention and control effect of the better; It is suggested that artificial uprooting (W1) and high frequency cutting (W2) should be used in the scattered distribution areas of Zephynchus chinensis, and that beneficial plant communities should be established. It can be directly seeded with Festuca vubra) (1: 1.5: 1 (S2) in Bromus inermis of Medicago sativa, and after chemical and physical control, it can also be supplemented with supplementary sowing to stabilize the control effect.
