细绿萍最适应的生长温度是18～22℃,18℃以下繁殖速度减缓,温度低于5℃停止生长,0℃以下就要死亡.因此细绿萍在室外不能越冬,需要采用一定的保护措施,才能保证供应春季繁殖的萍种.1 加热温室或日光温室内越冬 在温室内修筑萍床即可保证萍体越冬.室内萍床为由地面向下深40厘米的平床,床的大小视温室内可利用面积而定,下面垫20厘米的稻皮或格荛为隔凉物,其中加些六六六粉以防鼠害,然后铺塑料薄膜
The optimum growth temperature is 18 ~ 22 ℃, and the reproduction rate below 18 ℃ is slowed down, the growth is stopped below 5 ℃, and the death below 0 ℃ is required, so it is necessary to adopt certain protection Measures in order to ensure the supply of spring breeding Ping .1 heating greenhouse or solar greenhouse wintering in the greenhouse to build Ping bed to ensure the Ping body overwintering indoor Ping bed from the ground down 40 cm deep bed, bed size Greenhouse available area may be, the following pad 20 cm paddy or grid 荛 as a compartment cooling, which adds some 666 powder to prevent rodents, and then shop plastic film
