Abstract

A manipulation of zoysiagrass's lateral stems and soil-media; used for slope revegetation, is expected to facilitate the production of high-quality grass. To study the influences on the growth of zoysiagrass depending upon various soil-media conditions, two different types of soil are used. The results obtained - through investigation of its cover rates, leaf color and number - are summarized as follows. In mountain regions soil, there are no significant differences in growth and development of grass in treatments: zoysiagrass's lateral stems treatments with 1cm, 2cm, and 3cm soil-media and treatment with only seeding. Zoysiagrass, in most of the treatments, show about the same growth rates, and at the end, fair visual quality. Zoysiagrass's lateral stems treatments with 2cm, 3cm show slightly better growth, however, thickness of soil-media need not be more than 1cm to obtain an expected quality of lawn. In decomposed granite soil, there appears statistical significance in growth of the grass in treatments: zoysiagrass's lateral stems treatments with 1cm, 2cm, and 3cm soil-media and treatment with only seeding. The thicker the soil-media, the better the growth of grass, and that in treatment with seeding-only shows poor quality in general. And therefore, it is efficacious to plant in 3cm soil-media when quick formation of lawn is necessary; however, using 2cm soil-media is ultimately the most cost-efficient way of formation. But, when time allows - that is, more than three months - 1cm soil-media in decomposed granite soil is reasonable to formate just as effective lawn. And so when performing seeding, additional covering, fertilization or increasing the quantity of seed must be considered.
