近年来,我省坛紫菜人工养殖迅速发展,1981年养殖面积已达4.2万余亩,但大多数紫菜的采收均采用剪收法。紫菜的采收是紫菜养殖的重要环节。紫菜的产量、质量与紫菜采收方法有关,但过去对紫菜的采收方法研究的不多。一般认为紫菜的采收方法取决于有无单孢子苗,如条斑紫菜能大量放散单孢子,则采用拔收法;坛紫菜无单孢子,认为采用拔收会造成拔一株少一株,影响紫菜的产量,甚至担心多次拔收下去紫菜网会光头,无法进行生产。所以只允许在苗量密度大的情况下,拔收头一、二水菜作为疏苗的措施。随着时间的推移,坛紫菜采用拔收法的工艺,就这样逐渐地为部分群众所掌握。究竟坛紫菜能否采用拔收呢拔收对坛紫菜的苗量、产量和质量有何影响作者于1981年在同安县小嶝岛海区,进行了紫菜拔收与剪收方法的对比试验,观察二种采收方
In recent years, the rapid development of algae cultivation in our province, the breeding area in 1981 reached 42,000 mu, but most of the laver harvesting methods are used cut. Seaweed harvest is an important part of seaweed farming. The yield and quality of seaweed is related to the harvesting method of seaweed, but in the past, little research was done on the harvesting of seaweed. It is generally believed that the harvesting method of seaweed depends on the existence of monospore seedlings, such as Porphyra yezoensis can release a large number of single spores, the use of extraction method; algae without monospores, that the use of pulling will lead to pull a less a strain, Affect the production of seaweed, or even worried about pulling down the seaweed will be repeated bald, unable to produce. Therefore, only the density of seedlings in the case of large, pull the first one or two watermelon as sparse measures. With the passage of time, algae cultivation method using pull-off law, it gradually so as to grasp for some people. What altar can seaweed can be used to pull it off? Absorption of seaweed seedlings volume, yield and quality of the impact of Author in 1981 in Tongan Xian Xiaocao Island sea area, seaweed harvesting and harvesting methods comparison test observed Two kinds of recovery side
