蛤蜊播种技术是一种新型海草播种技术,该技术中,种子通过糯米糊粘在蛤蜊贝壳上,随蛤蜊穴居被埋入底质。为评价蛤蜊和糯米糊对种子成苗率的影响,以菲律宾蛤仔(Ruditapes philippinarum)和大叶藻(Zostera marina)种子为试验对象,设置了直接播撒种子(A1组)、直接埋种(A2组)、包埋糯米后播撒(B1组)、包埋糯米后埋入底质(B2组)、蛤蜊播种(C)5种处理,每种处理设置3个重复,在实验室的水槽中对其进行试验。结果表明:糯米糊对种子萌发有负面影响,但由于蛤蜊的行为使底质具有透气性,减轻了糯米糊对种子萌发的影响,种子成苗率可达到23.2%;海区试验中利用蛤蜊播种的两个样方中的成苗率分别为19.1%和9.9%。试验表明,蛤蜊播种技术适合作为一种经济、有效的播种技术用于海区海草床的建立和修复。
Clam sowing technology is a new seagrass sowing technology in which seeds are glued to the shell of a clam with glutinous rice paste and burrowed into the substrate with the cave clams. In order to evaluate the effect of clams and glutinous rice paste on seedling success rate, seeds of Ruditapes philippinarum and Zostera marina were used to directly seed the seeds (group A1) (Group B1), burying glutinous rice, then embedding substrate (group B2), and clam sowing (C). Three treatments were set for each treatment, It is tested. The results showed that glutinous rice paste had a negative impact on seed germination, but due to the behavior of clams, the permeability of the substrate was reduced and the effect of glutinous rice paste on seed germination was reduced. The seedling rate of seed could reach 23.2% The seedling rates of the two quadrats were 19.1% and 9.9% respectively. Experiments show that the clam sowing technology is suitable as an economical and effective sowing technology for seaweed bed establishment and repair.
