【摘要】：以醉馬草(Achnatherum inebrians)嚴重發(fā)生區(qū)域為研究對象,探究物理、化學(xué)和生物方法對醉馬草的防控效果,以期獲得適宜的防控方法。結(jié)果表明:不同防控方法在防控當年就對醉馬草種群高度、蓋度、密度和地上生物量表現(xiàn)為一定的抑制作用;對可食牧草蓋度、密度,群落多樣性指數(shù)、均勻度指數(shù)表現(xiàn)出一定程度的促進作用。綜合評價其防控效果,使用10%濃度草甘膦+皂粉(點噴)(H2)對醉馬草的防除效果較好;建議在醉馬草零星分布區(qū)采用人工拔除(W1),成片分布區(qū)采用高頻刈割(W2);若想建立有益植物群落,則可直接補播補紫花苜蓿(Medicago sativa)+無芒雀麥(Bromus inermis)+紫羊茅(Festuca vubra)(1∶1.5∶1)(S2);化學(xué)和物理防控后,也可輔助補播,以穩(wěn)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.
