白三叶是一种优良的地被植物,从1983年开始、北京城区共种植白三叶7万多平方米,普遍生长良好。针对白三叶在北京地区越冬率低的问题、采取浇水、覆土等措施,解决了这一问题。同时,通过白三叶的生长观察、土壤和植株分析测定以及小气候观测等试验表明,白三叶在美化环境、改良土壤和调节小气候等方面具有显著的作用。
White clover is an excellent ground cover plant. Since 1983, a total of more than 70,000 square meters of white clover has been planted in urban areas of Beijing, generally growing well. Aiming at the problem of the overwintering rate of white clover in the Beijing area, watering and soil covering are adopted to solve this problem. At the same time, through the observation of the growth of white clover, soil and plant analysis and the observation of microclimate, the experiment shows that white clover has a significant role in beautifying the environment, improving the soil and regulating microclimate.
