矮生百慕大为暖季型狗牙根属新颖草坪草种，９０年代初从美国引进，经４ａ多来引种繁殖推广，建植面积已近２００万ｍ２，受到长江中下游及其以南广大地区绿化部门和单位的好评。该品种表现适应性强、生长迅速、草层低矮、叶色深绿、节短叶小、耐践踏、耐高温干旱、且再生力强，适于景点绿化、休憩广场和高级运动场的草坪建植。通过２ａ的观察研究，比较系统地论述了该品种的主要生育特点，地上部匍匐茎和分枝的发生规律，以及日均温对它的青绿期的影响。并以矮生百慕大为主体，相应的对３种本地狗牙根的若干生长性状进行了比较。除了共同的特性，如发达的匍匐茎和极强的分枝和生根能力，更加突出了矮生百慕大特有的属性，为进一步开发利用提供了科学依据。同时对该品种在南京地区的主要病虫害也进行了调查，提出了一些可行的防治对策
Dwarf Bermuda is a warm-season bermudagrass new lawn grass species, introduced from the United States in the early 90s, the introduction of more than 4a breeding propagation, the construction area of nearly 2 million m2, by the middle and lower reaches of the Yangtze River and the vast green areas south Department and unit's praise. The variety has the advantages of adaptability, rapid growth, low grass layer, dark green leaves, short stubs, trampling resistance, high temperature and drought resistance, strong regeneration ability and suitable for greening of attractions, lawn construction of open squares and advanced sports grounds plant. Through the observation and research of 2a, the main growth characteristics of the breed, the occurrence of stolons and branches in shoots, and the effect of daily average temperature on its green color were systematically discussed. And to dwarf Bermuda as the main body, corresponding to the three kinds of local bermudagrass several growth traits were compared. In addition to the common features, such as developed stolons and strong branching and rooting abilities, Bermuda's peculiar attributes of Bermuda are highlighted, providing a scientific basis for further development and utilization. At the same time, the main pests and diseases of this variety in Nanjing area were also investigated, and some feasible control measures were put forward
