细绿萍不耐高温,在自然条件下越夏,因温度高、时间长(约二个月),萍体易因热害死亡。因此,在没有泉水的平原或半山区,必须选择遮光场所或搭置荫棚,或其它降温措施,才能获得少量萍种。采用孢子果越夏,进行秋播育苗,方法简便,家家户户都能搞,是解决细绿萍越夏保种困难的好方法。兹将近年来孢子果育苗试验研究结果 Fine green duckweed is not resistant to high temperatures, the summer under natural conditions, due to high temperature, long time (about two months), Ping body easily died of heat damage. Therefore, in plain or semi-mountain areas where there is no spring water, it is necessary to choose a shading site or shade house or other cooling measures in order to obtain a small amount of species. The use of spores and more summer, autumn sowing, the method is simple, every household can engage in, is to solve the fine green Pingzhuo good summer seedling a good way. In recent years, spore fruit nursery test results
