近几年我省地瓜生产有很大发展,但是有些人对秧苗栽插时期与产量的关系缺乏全面了解,认为地瓜秧“皮拉”,早栽几天,晚栽几天对产量影响不大,有些地方所用的秧苗全部靠外地调运。究竟地瓜秧苗拔后什么时候栽插好呢?为了搞清这个问题,1983～1984年我们进行了地瓜秧苗存放时间对产量影响的试验。 In recent years, great efforts have been made on the production of sweet potatoes in our province. However, some people lack a comprehensive understanding of the relationship between the planting and planting of seedlings and their yield. They think that the sweet potato seedling “Pila” In some places all the seedlings used by the transfer of the field. After the sweet potato seedling planted when inserted planted it? In order to clarify this issue, 1983 ~ 1984 we conducted sweet potato seedling storage time on the yield impact of the experiment.
