摘　　要：青苔生长必须同时满足的条件为生殖孢子、适宜的温度、营养物质和光照条件。人工养殖的稻田,放苗前的孢子可用药物杀灭;营养物质可以通过多种手段向有利于小龙虾生产的藻类和水草转化;采用培肥水质和物理遮光的方法,使青苔孢子得不到阳光照射而生长不良,从而减轻对稻田养殖小龙虾的危害。Conditions of reproductive spores, suitable temperature, nutrients and lighting conditions should be met for the moss growth. In artificially farmed rice fields, spores release can be killed by drugs before seedling.Nutrients can be converted to algae and aquatic plants that are beneficial to crayfish production by various means.Fertilizing water quality and physical shading methods can suppress moss spores due to the poor sunlight, which can reduce the damages for crayfish cultured in rice fields.
