摘要
无芒雀(Bromusinermis)、扁穗冰草(Agropyroncrstatum)及芨芨草(Achnatherumsplendens)均是北方最常见的优质牧草、饲料。针对北方地区这3种牧草的栽培种植适时问题,采用纸上萌发试验法,研究了不同温度下这3种牧草种子的萌发特性,以期确定其适宜的萌发温度范围。结果表明:无芒雀麦种子的适宜萌发温度范围广,为恒温10~30℃之间及5~40℃之间的变温;扁穗冰草种子的适宜萌发温度范围也较广为恒温10—25℃之间及5~30℃之间的变温;芨芨草种子的适宜萌发温度范围较小为恒温15—25℃之间及10—30℃之间的变温。
Bromus inermis,Agropyron cristatum and Achnatherum splendens are the most common qualified forage grass and feed in the north. For the timely question of cultivation in northern, using the method of germination on the paper studying the germination charac- teristics of the three kinds of grass seed in various temperatures, determining the appropriate germination temperature range. The results showed that the suitable germination temperature range of Bromus inermis Leyss seed is big, is constant temperature 10~C to 30~C and the variable temperature between 5~ to 40 0C ; The suitable germination temperature range of Agropyron cristatum seed is big, is con- stant temperature 10℃ ,25℃ and the variable temperature between 5℃ to 30℃ ; The suitable germination temperature range of Ach- natherum splendens seed is small, is Constant temperature 15℃ to 25℃ and the variable temperature between 10℃ to 30℃.
