摘　　要：稻田养殖中,田块长期覆水,晒田时间较少,特别是夏季高温天气,由于养殖渔类,水体营养丰富,容易发生藻害,降质减产.介绍了稻田养殖中几种主要有害藻类(蓝藻、水绵、刚毛藻、水网藻)产生的原因与危害,并结合水稻(一季稻)生长时期从四个季节简述了有效防控有害藻类的技术.In rice paddy farming,the field has been covered with water for a long time.and there is less time for drying in the field. Especially in the high temperature weather in summer.due to the fanning and fishing.the water body is rich in nutrients, and it is prone to algae damage .reducing quality and reducing production. This paper introduces the reason and harm of several major harmful algae( Cyanobacteria, Spirogyra communis, Cladophora, Hydrodictyon reticulatum ) in paddy field fanning. Combined with the growth period of single - season rice.it summarizes the prevention and control technology in four seasons ( spring,summer.autumn and winter).
