稻田养萍(红萍)是发展稻田肥源,增产粮食的一项有效措施。红萍是一种浮生水面的蕨类植物,既怕高温又怕低温,以25—32℃最适合它的生长,气温在5℃以下时就不生长了。我省冬季气温鞍低,平均为零下2—4℃,最低达零下6—7℃,以致冬季萍株发生大量死亡,影响下年的萍种供应。因此,保护红萍安全越冬,是红萍推广上的一个重要问题。现将我站几年来摸索的红萍越冬方法介绍如下。
Paddy field Yangping (Hongping) is an effective measure to develop paddy field fertilizer source, increase grain production. Hongping is a kind of floating surface ferns, both afraid of high temperature and low temperature, with 25-32 ℃ most suitable for its growth, the temperature does not grow below 5 ℃. The winter temperature in our province is saddle low, with an average of -2-4 ℃ and a minimum of -6-7 ℃. As a result, a large number of deaths occur in the winter and affect the supply of the plant species in the next year. Therefore, the protection of Hong Ping safe winter, Hongping promotion is an important issue. Now I stand for several years to explore the method of Hongping winter is as follows.
