天胡荽新型草坪引种试验研究

An Introduction Test of Hydrocotyle sibthorpoioides,a New Type of Lawn Grass

为探索开发适用于林下半阴环境的新型草坪草种类,选择园林绿地常见杂草天胡荽为试材,对其在不同环境中的成坪速度、坪用价值等方面进行了研究。试验结果表明:天胡荽在林下湿润环境中,生长良好,外来杂草不易入侵,成坪率高,常绿美观,具有一定的抗虫性。天胡荽可作为林下阴湿环境草坪草利用。

The lawn formation speed and utilization value of Hydrocotyle sibthorpoioides under different growth environments were studied to develop the new grass type for lawn under the forest with semi-shady and humid environment. The results showed that Hydrocotyle sibthorpoioides with a high lawn rate, certain resistance to pest, strong anti-invasion ability of exotic weeds and beautiful evergreen could grow well under the forest with semi-shady and humid environment. Therefore, Hydrocotyle sibthorpoioides should be used in lawn construction under the forest with shady and humid environment.
