7份新疆狗牙根材料品比试验

通过对7份新疆狗牙根材料的品比试验，对其生物学特性（生育期、形态特征、生物量）、坪用性（质地、盖度、颜色、均一性、耐践踏性、杂草状况、绿色期）、对环境的适应性（越夏、抗病虫害、越冬率）等方面进行研究。结果表明：供试新疆狗牙根草坪草坪用性综合评价为：新疆狗牙根C1最好，其次为新疆狗牙根C2，新疆狗牙根C5坪用性较差；从生物学特性上看，新疆狗牙根C2植株低矮、叶片细小、密度大、茎短且细、绿色期长，很适合于草坪草种的选择，而新疆狗牙根C5植林高大，叶片长而宽，茎长且粗。草产量高，根茎粗，适宜做牧草以及用于建植固上护坡等草坪，其他狗牙根材料居中，可用于牧草和划坪兼用。

Verieties Comparison Experiment on Native Bermuda grass Resource in Xinjiang

The verieties comparison experiment on 7 Bermuda grass materials of Xinjiang about biological characteristics and the lawn estimation,was carried out during 2003-2005.The results indicated that according to the lawn estimation,Xinjiang Bermuda grass C_1 received the highest score,Xinjiang Bermuda grass C_2 took the second place,while the Xinjiang Bermuda grass C_5 was the lowest;As concerns the biological characteristics,Bermuda grass C_1 had low-height,small-leaves,great-density,thin-stem and long green period,which was fit for using of turfgrass,while C_5 had great-height,long and wide leaves,high-yield,which was suitable for choice of forage and establishing the lawn for soil protection,the others could be used in forage and lawns.
