我区安化县大福农技站张岸举同志,和大荣公社早粮制种场工人一起,在半地下式撮箕形(北墙高、南墙低象个撮箕)苗床的基础上,经过多次研究,改成为半地下式屋脊形苗床,1978年10月底做好床后,11月4日扦苗,此时薯藤已经过一次霜打,大部分藤叶开始枯萎,比一般越冬薯苗迟扦了半个月左右,共计扦苗600株,比正常密度少扦了1,000多苗子。尽管动手较迟,迄至1978年3月5日检查,成活450株,成活率仍达75%以上。实践证明,这种新式床(指地下式屋脊形苗床,下同)比原来的老式床(指地上式、地下式、半地下式,下同)优越得多,现介绍如下。
Zhang Anju from Dahua Agricultural Technology Station in Anhua County of our district, together with the early-grain seed farms of Daiei Commune, went through more beds on the basis of a semi-underground type of Keiji-shaped beds (with high northern wall and low south wall) Sub-study, into a semi-underground type roof seedbed bed, do a good job in bed in late October 1978, November 4 cuttings, this time the potato has been a frost fight, most of the vine leaves began to wilt than the general winter fry After a delay of about half a month, a total of 600 seedlings, less than the normal density sticks more than 1,000 seedlings. Despite its late start, as of March 5, 1978, it has survived 450 and survived more than 75%. Practice has proved that this new bed (refers to the underground roof seedbed, the same below) older than the original bed (referring to the ground type, underground type, semi-underground type, the same below) is much more superior, are described below.
