几种草坪草和牧草在兰州地区的引种适应性研究

国外引进的6个优良草坪草品种：Bardur(百舵)、Barfina(百妃娜)、Barcotsa、Barkole(百克星)、BarLp95-1和BarPc74及牧草品种——紫花苜蓿三得利(Sanditi)在中国兰州(寒冷半干旱带)进行品种的评定和适应性研究,结果表明：除在气候异常、高温多雨的夏季,Barcorsa表现不佳外,6个草坪草品种适宜在中国寒冷半干旱带推广;紫花苜蓿三得利(Sanditi)的植株高大,产量高、抗寒、抗倒伏,与当地品种相比,优势明显;并且在兰州地区1年刈割4次,可收到更好的增产效果。

Adaptability of introduced turfgrass and herbage varieties to Lan zhou areas in China

6 choice turfgrass and forage varieties were introduced from overseas: Bardur, Barfina, Barkole, BarLp95-1, BarPc74, and Medicago sativa var. Sanditi, to guage their adaptability to cold, semi-arid areas. They were introduced to Lanzhou to a cold, semi-arid area, and assessed in field experiments. The varieties all grew well, apart from Barcorsa etc. under unusually high temperatures and wet weather in summer. M. sativa var. Sanditi is big, high yielding, cold tolerant, and resists lodging, showing obvious superiority over local varieties. Moreover, in the Lanzhou region, it seems insufficient to cut it three times a year, but at the beginning of flowering cutting should begin, cutting four times annually, giving an increase in production.
