외국산 야생화초지의 생육특성, 계절개화분포 및 식생변화에 관한 연구

Abstract

ABSTRACTThis study was carried out in the Chungnam National University grassland experimental field from October, 2007 to December, 2009 in order to find out the growth characteristics, seasonal anthesis distribution and botanical composition of the wildflowers which were altogether composed of 70% sheep fescue and 30% introduced wildflowers. The experimental species contained 23 species in total to which sheep fescue(fundamental turfgrass) and 22 introduced wildflowers belonged. At the time of the anthesis of the wildflowers, the average plant height was 29.7cm at first growing season and 34.1cm at second growing season. They bloomed out into eight colors, but into simplified two colors during August, September, and October. The blooming season leant toward April and June and from August there were lots of difficulties in the wildflower blooming and the maintenance of their consistency. The botanical composition of wildflowers, sheep fescue, and weeds were 21%, 64%, and 15% in the first growing season(2008) and 19%, 65%, and 16% respectively, in the second growing season(2009). Based on this result, cultivating the introduced wildflower grassland has more difficulty because there is some difficulty in the wildflower seasonal distribution and the maintenance of its consistency. And thus, the introduction of more various wildflower such as perennials and flowers blooming after summer, and the seed-mixture combination method should be studied.(Key words:Introduced wildflower pastures, Growth characteristics, Seasonal distribution, Botanical composition)
