沈阳地区用暖季型草坪植物铺建草坪,在夏季是很美丽的,但一般在9月下旬或10月初就进入枯黄期,长达半年以上。为丰富我市草坪植物种类,延长草坪的绿色观赏期,选择引进冷季型草坪新品种,是沈阳地区园林绿化的重要内容之一。近年来通过引种试栽,已选出早熟禾属(Poa)、剪股颖属(Agrostis)、羊茅属(Festuea)等冷绿型草坪的一些新种。这些草坪品种,在沈阳地区绿色期可长达230—270天,甚至在雪的覆盖下仍然保持鲜绿的色泽。现将紫羊茅的引种栽培、生物学特性的研究,简介如下。紫羊茅(Fegtuca rubra L.)又称红
Shenyang lawns with warm-season lawn paving the lawn, in the summer is very beautiful, but generally late September or early October into the yellowing period, up to more than six months. In order to enrich the lawn plant species in our city and extend the green ornamental period of the lawn, the introduction of new varieties of cold-season turfgrass is one of the important contents of landscaping in Shenyang. In recent years, some new species of cold-green lawns such as Poa, Agrostis and Festuea have been selected through trial planting. These turfgrass varieties can last up to 230-270 days in the green area of Shenyang, and even maintain the fresh green color even under the cover of snow. Now the introduction of fescue cultivation, biological characteristics of the research, the following is as follows. Red fescue (Fegtuca rubra L.), also known as red
