摘要: 本文就不同品种在不同插苗期的试验,分析研究其茎蔓生长及块根膨大的相互制约及其与温度条件的关系。初步结果认为:甘薯生长前期的高温日数应不短于60—90天,且后期要有一定适温日数,对块根膨大才有良好作用。晚熟种对前期高温日数要求较长,而早熟种则可相对较短。

Abstract: In this experiment,the cuttings of three varieties of sweet potato,North China 117,(early),Nancy (late),and Kao Tian Zi (late) were planted on six different dates,1/6,16/6,1/7,16/7 1/8 and 16/8 1957 to observe their enlargement of tubers and the growth of the topson fixed periods.1.The vine growth r
