水稻田里会滋生一定数量的红浮萍,这时,光照尚且充足,又加之普遍在田里压上瓜豆藤蔓、青草等,在草食性鱼类食用之余,便很快腐烂变成了肥料,这就为红浮萍的迅速生长提供了优越的条件。我们仔细地观察了鱼类和这种植物的关系,发现无论是草食性鱼类或杂食性鱼类都不太喜欢这种植物,相反,它给鱼类带来了不良的影响。

The paddy field will breed a certain amount of red duckweed. At this time, the light is sufficient and sufficient. In addition, it is generally pressed in the fields to depress the melons, vines and grasses, etc., and when herbivorous fish is consumed, they quickly decay into Fertilizers, which provide the excellent conditions for the rapid growth of red duckweed. We looked closely at the relationship between the fish and this plant and found that neither herbivorous nor omnivorous fish preferred the plant, on the contrary, it had a detrimental effect on the fish.
