摘要

利用化感作用控制杂草是减少对合成除草剂依赖的一种策略。研究了鼠尾茅(Vulpia myuros, L.)的化感作用。林祖嘉Gmel)。尾茅水提物对芥蓝根、芽生长有抑制作用。尾茅粉对白菜根、茎的生长也有一定的抑制作用,且呈浓度依赖性。鼠尾茅水提物和粉末对白菜根、芽生长的影响无显著差异。化感活性物质可能从粉末中浸出到生物测定培养基中,这些物质可能抑制菜根和芽。此外,该粉末对莴苣、紫花苜蓿、金盏花、马地黄、何首乌的根、梢生长均有抑制作用。柱头刚体。,刺青藻(L.)测定。和棘藻呈浓度依赖关系。因此,鼠尾茅可作为各种农业环境下的杂草抑制残留物或土壤添加剂材料,以减少对合成除草剂的依赖,这有待于进一步的实地研究。

Potential of Rattail Fescue Powder for Weed Management
Controlling weeds through allelopathy is one strategy to reduce dependency on synthetic herbicides. We investigated possible allelopathic effects of rattail fescue ( Vulpia myuros (L.) C.C. Gmel.). Water extract of rattail fescue inhibited root and shoot growth of cress ( Lepidium sativum L.). Powder of rattail fescue also inhibited the root and shoot growth of cress in a concentration dependent manner. The effectiveness of the water extract and powder of rattail fescue on the cress root and shoot growth was not significantly different. Allelopathic active substances may be leached from the powder into bioassay medium and those substances may inhibit the cress roots and shoots. In addition, the powder inhibited root and shoot growth of lettuce ( Lactuca sativa L.), alfalfa ( Medicago sativa L.), Phleum pratense L., Digitaria sanguinalis L., Lolium multiflorum Lam. Lolium rigidum Gaund., Echinochloa crus-galli (L.) Beauv. and Echinochloa colonum L. in a concentration dependent manner. Therefore, rattail fescue could be useful for a weed suppressive residue or soil additive materials in the variety of agricultural settings to reduce dependency on synthetic herbicides, which should be investigated further in the field.
