龙须菜系江蓠属的一个优良品种,地处外海的莆田市南日岛于2001年9月引进改良型龙须菜(KF—981品系)苗种,结合海岛实际情况,经过1年多时间进行创造性开展浅海筏式试验养殖,取得可喜进展。试验表明,改良型龙须菜浅海筏式养殖具有投资省、成本低、效益高、风险少和易为群众所接受等优点,今年南日岛迅速发展养殖1800亩,产值可增900多万元,成为我镇渔民增收的新亮点。其养殖技术要点如下: 一、海区选择 改良型龙须菜光照强度的要求较高,养殖海区应选择海水较澄清、在最低潮时水深2.5米以上,潮流畅通,无污染,有一定的淡水流人,营养丰富,海水比重在1.005—1.025为宜,水温在5—27℃内,pH值在7.8—8.2为宜。
Asparagus is a genus of genus Gracilaria, located in the outer sea of Putian City, South Island in September 2001 the introduction of improved asparagus (KF-981 strains) seed, combined with the island’s actual situation, after more than a year We have made gratifying progress in creatively carrying out shallow-sea raft test breeding. The experiment shows that the improved asparagus aquaculture has the advantages of low investment, low cost, high efficiency, low risk and easy acceptance by the masses. This year, the rapid development of the south island breeding 1800 mus, the output value can be increased by 900 million yuan , Become a new bright spot in my town fishermen income. The main points of aquaculture techniques are as follows: First, the sea area should have a higher light intensity for improved asparagus, seawater should be selected to be clearer in the aquaculture area, and the water depth should be 2.5 meters or above at low tide with smooth flow, no pollution and a certain fresh water flow People, nutrient-rich, seawater proportion of 1.005-1.025 is appropriate, the water temperature in 5-27 ℃, pH value of 7.8-8.2 is appropriate.
