The magic 39 ° north latitude undaria pinnatifida seedling breeding in summer has a "guarantor"

At present, Dalian undaria pinnatifida exports more than 80% of the country, accounting for more than 60% of the Japanese market share. In summer every year, fishermen should breed undaria pinnatifida. The temperature of the nursery should be controlled at 18~27 ℃, and the constant temperature and oxygen should be maintained for 24 hours during the three-month incubation period. This requires that the level of the oxygen pump and temperature control system should be stable. Dalian Lushun Power Supply Company organized Lei Feng's Communist Party service team to carry out fishing related electricity services, "protecting" the summer seedling breeding of Undaria pinnatifida.

Undaria pinnatifida growing in the sea area of Dalian is known as the "king of seaweed". Dalian Undaria pinnatifida was selected as a national agricultural product protected by geographical indication on September 13, 2010. Today, Dalian Undaria pinnatifida has become not only a popular aquatic product in the world, but also an important industry of Dalian's marine economy, a booster for fishermen's employment and income increase, and has promoted the economic development of coastal rural areas.

According to experts, Undaria pinnatifida is bred and propagated in summer every year. The temperature in the nursery should be controlled at 18~27 ℃, and the constant temperature and oxygen should be maintained for 24 hours during the three-month cultivation period. During the seedling period, I devoted myself to the care so that I could get a good price after the sea opening in September. However, the increase of extreme weather such as high temperature and typhoon in recent years also made me worry about whether the power consumption of oxygen pump and temperature control system could be stable.

The breeding area is more than 6000 mu, and Dalian Lushunkou District dances the "Harvest Song" of Undaria pinnatifida"
