摘要
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。
Tifdwarf, a new variety of warm season turfgrass belonging to Cynodon, was introduced from America in the early 1990’s. Its establishment areas reached nearly two million square meters after 4-year introduction, breeding and extension. It was appreciated by the afforesting departments and units in the middle and low reach of Changjiang River and South of China. Having the characteristics of strong adaption, rapid growth, low grass layer, dark green colour, short knot, small leaf, traffic tolerance, hot and dry tolerance, and strong regeneration, it was usable to scenery afforesting and turfgrass establishment of the resting square and advanced spots ground. Through systematical observation and research for two years, we have mastered its major reproductive characteristic, laws of its upground stolon growing and branching, and effects of the day average temperature on its green period. Some reproductive characteristics of Tifdwarf were comparied with three local varieties of Cynodon. Besides some common characteristics such as well-developed stolon, strongest branching and rooting capacity, some specific qualities of Tifdwarf have been found in our study, which provided a scientific basis sor further development and utilization. Also some practical preventive methods and control measures are put forward to deal with the major diseases and pests found in the investigation in Nanjing.
