条斑紫菜栽培生产近几年来面临许多严重问题，主要是原藻质量和产量下降，绿藻等发生频繁．病害也时有发生，栽培产量最低年景每亩还不到73公斤压水鲜菜。受原藻产量的限制，现有加工机械的实际加工产量仅为其加工能力的一半左右。生产效益的下降，影响了整个行业的经济效益．
Porphyra cultivation cultivation in recent years facing many serious problems, mainly due to the original algae quality and yield decline, such as frequent occurrence of green algae. Diseases have also occurred from time to time, the minimum annual yield of cultivation less than 73 kg per acre fresh vegetables. Due to the limited production of protozoa, the actual processing capacity of existing processing machinery is only about half of its processing capacity. The decline of production efficiency has affected the economic benefits of the entire industry.
