摘要
研究了不同修剪高度和修剪频率条件下,南京地区高羊茅的生长状况和草坪质量。方差分析表明,低剪(4cm)的生长量明显高于中剪(6cm)和高剪(9cm),而草坪质量低于高、中剪;高频率修剪(1周2次)的生长量显著高于中频(1周1次)和低频(2周1次),而草坪质量低于中、低频。因此,在管理上应适当采取高剪(6~9cm)和低频(1~2周1次),既可以提高草坪质量,又可减轻管理强度。试验结果表明,南京地区高羊茅可能存在夏季和冬季两个休眠期。
The growth and turf quality of Tall Fescue were studied under different mowing heights and frequencies. Analysis of variance showed that the growth mowed at 4 cm height was significantly more than that at 6 cm and 9 cm, yet turf quality was poor at the 4 cm. When mowed at high frequency (twice a week), the growth was significantly more than medium (every week) and high (every two weeks) frequencies, but turf quality was poor for the high frequency. So, it is necessary to carry out mowing at a greater height and less frequency so as to increase turf quality and minimize management. The results also implies that there may be 2 light dormant periods in autumn and winter in Nanjing area.
