多年生黑麦草(Lolium Perenne)生长期长,再生性强,耐践踏,是一种优良的禾本科牧草。随着人工种草养畜业的发展,多年生黑麦草在改良草山草坡建立人工草地中发挥了极其重要的作用。但在不同的气候条件下,多年生黑麦草易感染锈病和网斑病,往往给牧草生产带来巨大损失。本试验于1985—1986年在新西兰专家诺尔斯顿(M.P.Rolston)博士指导下进行。
Perennial ryegrass (Lolium Perenne) grows long, reproducible, trample resistant, is an excellent grasses. With the development of artificial grass raising and livestock husbandry, perennial ryegrass has played an extremely important role in the establishment of artificial grassland for grassland slope improvement. However, perennial ryegrass is susceptible to rust and leaf spot disease under different climatic conditions, which often result in huge losses to pasture production. The trial was conducted between 1985 and 1986 under the guidance of Dr. New Zealand expert Dr. M.P.Rolston.
