我们公社自1975年搞薯藤冬保试验,两年的实践证明,薯藤冬保并不难,但也决不是轻而易举的事。思想上高度重视,工作上专人负责,技术上严字当头的单位,大多两年都获得成功,反之,往往失败,或者上年成功,下一年失败。现将有关技术问题调查总结如下。一、充分利用有利的地形地物,选好苗床床址我社革命大队二队,两年都将苗床建在1.5米高、1米宽的大渠前,后面有居民点,防寒条件好,日平均温度比平地高2—3℃,地势高燥,排水方便。1975年床内最低温度为10℃,越冬成活95%,1976年床内最低温度为7.5℃,越冬成活75%。而三队两年都在平地建床,虽然搭有阳棚,但防寒条件不及二队好。1975年床内最低温度为7℃,越冬成活率55%;1976
Our commune since 1975, potato vine winter trial, two years of practice has proved that potato vine winter security is not difficult, but by no means easy thing. Think highly of the work, the person responsible for the work, technically serious flawed units, most of them have succeeded in the past two years, on the contrary, often fail, or last year’s success, the next year failed. The survey of technical problems is summarized below. First, take full advantage of the favorable terrain, choose the best seedbed bed site I Revolutionary Brigade two teams, two years will be built in 1.5 meters high bed, 1 meter wide channel, behind a residential area, cold conditions, The daily average temperature is 2-3 ℃ higher than the ground, the terrain is high and dry, and drainage is convenient. The lowest temperature in bed in 1975 was 10 ℃, 95% survival in winter, the lowest temperature in bed in 1976 was 7.5 ℃, winter survival of 75%. The three teams in the two years are building beds in the ground, although the sun shelter, but less than the second team cold conditions. The lowest temperature in bed in 1975 was 7 ℃, survival rate of overwintering 55%; 1976
