在我省大面积生产中,花生均采用春播留种,但春花生种子发芽势弱,发芽率低,难于全苗。近年来,产区不少单位去广东调秋花生种子,其出苗率虽高但花费很大。在长沙地区气候条件下能否种秋花生?前人很少研究。为了探讨我省花生秋播留种技术,并为花生育种当年增加世代、加速选育进程? In large-scale production in our province, peanuts are spring sowing, but peanut seed germination weak, low germination rate, it is difficult to seedlings. In recent years, many units in the producing areas have transferred autumn peanut seeds to Guangdong, although the emergence rate is high but it costs a lot. Can we planted autumn peanuts in Changsha climatic conditions? In order to explore the province of peanut planting technology for autumn planting, and to increase the generation of peanut breeding that year, to speed up the breeding process?
