冷地型草种又叫寒季型或冬绿型草坪植物。其生长发育最适温度为15—24℃,主要分布在寒温带、温带及暖温带地区。冷地型草种的主要特征是:耐寒冷、喜湿润冷凉气候,抗热性差。在严寒的冬季由冷地型草种建成的草坪仍是一片绿草茵茵,与一经打霜茎叶枯萎退绿的暖地型草种形成鲜明的对比,因而冷地型草坪也越来越受到人们的青睐。上海近年来应用的冷地型草种主要有禾本科的剪股颖属、早熟禾属、羊茅属、黑麦草属中的匍茎剪股颖(本特草)、草地早熟禾(瓦巴斯草)、苇状羊茅(高羊茅),细叶羊茅和黑麦草等。
Cold-type grass, also known as cold-type or winter-green lawn plants. The optimum temperature for growth and development is 15-24 ℃, mainly distributed in cold temperate zone, temperate zone and warm temperate zone. The main features of cold-type grass is: cold-resistant, hi humid climate, poor heat resistance. In the frigid winters, grassy lawns built from cold-type grasses are still a green grass, in sharp contrast to warm-type grasses that have withered off the frost and green leaves and thus become more and more affected by cold-type lawns People’s favor. In recent years, the cold-type grasses used in Shanghai mainly include Gramineae genus, Poa, Fescue, Lolium perenne in the genus Lolium (Bentgrass), Poa pratensis Sri Lanka grass), tall fescue (tall fescue), fine fescue and ryegrass and so on.
