红萍是一种速生高产的水生绿肥。它具有繁殖快、产量高、肥效好等优点。实践证明,稻田养萍不仅能使当季水稻增产,而且还能改良土壤,增加地力。通过观察试验,我们对红萍生长繁殖与气象条件的关系有了一些初步认识。 气温 温度的高低,对红萍的生育有直接影响。温度不但关系到红萍的繁殖速度、体型、颜色,还影响红 Hongping is a fast-growing aquatic green manure. It has the advantages of fast propagation, high yield and good fertilizer effect. Practice has proved that rice paddies not only increase the yield of paddy rice season, but also improve soil and increase fertility. Through the observation and experiment, we have some preliminary understanding of the relationship between the growth and reproduction of Rhizoma and meteorological conditions. The temperature of the temperature level has a direct impact on the fertility of Hongping. The temperature is not only related to the breeding speed of red duckweed, size, color, but also affect the red
