摘要
本文通过四份来源于我国亚热带地区的狼尾草属野生种材料:84-21乾宁狼尾草、84-39-1中型狼尾草、87-02中型狼尾草和83-48-12中型狼尾草在黄土高原地区的引种与观察,对其适应性和主要农艺性状进行了比较和评价。结果表明,在上述四份材料中,产草量以84-39-1最高,而以87-02最低;越冬性以84-39-1最好,而以84-48-12最差;分蘖数以83-48-12为最多,而以84-21最少;生育天数87-02最短(87天),84-21最长(109天);成熟时株高83-48-12最高(110.5cm),84-39-1最矮(87cm)。指出84-39-1中型狼尾草是温带地区可于推广的亚热带材料。此外,对温带干旱地区如何开发利用狼尾草属牧草提出了对策意见。
In this paper, through the introduction of four kinds of materials of wild Pennistum species from tropical or subtropical area of China: P.qianningense (No.84-21), P.Longissimum ver. intermedium (No.84-39-1, No.87-02 and No.83-39-1, No.87-02 and No.83-48-12) into the in this area comparison and evaluation about the adaptability and main agricultural characteristics of them were carred out. It was founded that the forage yield of 84-39-1 was the highst; the 84-39-1 was the best to winter hardiness; about the tillering ability, the 83-48-12 was best to winter hardiness; about the tillering ability, the 83-48-12 was the strongest; about the length of period from seedling stage to mature, the 87-02 was shortest (87days) and the 84-21 longest (109 days); and the mean height of plants at mature stage of the 83-48-12 was the tallest (110.5cm) It was pointed out that the 83-39-1 P.Longissimum var.intermedium was the most valuable materil to be extented in pennistum species in semi-arid area of the temperate zone was suggested.
