摘　　要：目前我国海带养殖面积约15万hm2,年产干品27万t,占世界海藻总产量的50%。三十烷醇(TA)乳粉可显著提高海带的产量和品质,海带苗经2mg/LTA浸泡2h后放养,能促进假根生长,提高保苗率,增加叶绿素、岩藻黄素含量,促进碳、氮代谢,增加干物质积累。处理比对照平均增收干品657t/hm2,增产率为35%。同时,海带可比对照增收碘2424kg/hm2、褐藻胶1665t/hm2、甘露醇1278t/hm2。TA乳粉属国内外首创,具有无毒、高效、成本低、不变质及贮运方便等优点,已在全国海带上推广16万hm2,创经济效益3亿多元。At present,the breeding area of kelp in China is about 15000 hectares,and annual yield of dry product is 270 000 tonnes accounting for 50% of the total yield of seaweed in the world.TA emulsive powder can remarkably increase the yield and improve the quality of kelp.After the kelp seedling soaked in 2 mg/L TA solution for 2 hours and then put into breeding,the growth of rhizoid can be promoted and the seedling preservation rate can be raised,the content of chlorophyll and fucoxanthin increased,photosynthesis rate raised,accumulation of dry substance increased,activity of PEP carboxylase raised,metabolism of carbon promoted,activity of nitric\|reductase raised,metabolism of nitrogen promoted,absorption of nitrogen,phosporous,potassium increased,growth and development promoted,contents of nucleic acid and protein raised,physiological adjusmtent strengthened,anti\|disease property strengthened,rate of incidence of disease reduced.The yield of dry substance increased by 6 5 t per hectar in average compated with the treatment on the blank,that is increased by 35%.At the sametime,24 24 kg iodine,1 665t brown alg gum,and 1 278 t mannitol in kelp are increased per hectar.TA emulsive powder is a pioneer product at home and abroad.It has the advantages of non\|toxic,high efficiency,low cost,no deterioration and convenience in storage and transport,etc.It has been popularized in 15 000 hectares in the whole country and the economic benefit is more than 300 million yuan.
