新年伊始,宁波宁海湾迎来了一年中最忙碌的季节。当地渔民正忙着对经过海水养殖后的海带苗进行夹苗。所谓夹苗,就是把养大的海带苗夹在麻绳上。海带苗能否在水下抵御住随时打来的风浪,最终长成粗壮的海带,全靠工人们的夹苗力道。“夹苗后就可以把海带种到海里养殖了。”大佳何镇海带养殖户郑绍义介绍,海带一定要在流大、浪小的海区生长,潮水越急,海带长得越大。外海区是养海带的好地方。除了水域对海带的生长有影响外,麻绳上夹海带苗的稀疏程度也会影响海带的大小。在6℃至8℃的水温环境中,海带生长较快,0℃时就停止了生长。20℃以上的水温,海带不仅不会生长,反而会糜烂。所以每年1月至4月,
At the beginning of the new year, Ningbo Ninghai Bay ushered in the busiest season of the year. Local fishermen are busy holding seaweed seedlings after mariculture seedlings. The so-called folder seedlings, is to raise the kelp seedlings caught in the hemp rope. Kelp seedlings can withstand the water at any time withstand the storms hit the sea, and eventually grow into a robust seaweed, thanks to the strength of the workers folder seedlings. “After the seedlings can be kelp species to the sea breed.” Great Ho Zhenhai seaweed farmers Zheng Shaoyi introduction, kelp must be large, wave small sea growth, the more urgent tide, the greater the kelp grows. Outer Sea is a good place to raise kelp. In addition to the influence of water on the growth of kelp, the sparseness of the kelp on the hemp will also affect the size of the kelp. In the water temperature environment of 6 ° C to 8 ° C, the kelp grows faster and stops growing at 0 ° C. 20 ℃ above the water temperature, kelp will not grow, but will erosion. So every January to April,
