摘要
奇台苏丹草是一种优势高产牧草,由于建立起以提纯复状为目标的三级良种繁育体系,分三次采种,对灾害性大风的预防措施,播种前的选、浸、拌种工作和贯彻执行了种籽管理的各项法令,使种籽产量突破3000kg/ha增产34％,在加强管理的基础上,达到3750～4200kg/ha是可行的。
Qitai sudan grass is a good grass with high quality and forage yield. Because of the establishment of the three—class seeds multiplication system in which seeds are harvested three times, reduced the seed loss from damaging wind, deaned and sterlized seeds with pestcide before sowing and the implement of seeds management regulations, seed yield has come over 3000 kg/ha, increased by 34％. With intense management, it is possible for the seed yield to reach 3750～4200 kg/ha.
