摘　　要：对提高黔花生二号繁殖系数的5种快速繁殖方法进行了研究和比较。结果表明,5种方法对提高黔花生二号繁殖系数均有效,单粒稀播高倍繁殖法可提高20.8%～172.0%;扦插无性繁殖法可提高40.5%;一年两季快速繁殖法可提高90.5%;侧枝压枝法可提高20.2%;南繁加代法可提高89.9%。Five rapid propagation methods for Qian Hua Sheng No.2 were studied.The results were as follows： The five methods can increase the propagation-coefficient effectively.The propagation-coefficient was increased about 20.8%~172.0% by high times multiplication with single grain thin-sowing,40.5% by asexual propagation of cutting,90.5% through two generations in a year,20.2% by lateral pressure branch method,89.9% by increasing generation in south China.
