Nori cultivation net

Abstract

The invention discloses a nori cultivation net which comprises net lines, net meshes, blending twisting threads, PVA (polyvinyl alcohol) monofilaments, polyethylene monofilaments, impregnation polyester threads or impregnation nylon threads, a net length and a net width. The net lines are made up of two strands or three strands of blending twisting threads. The net width is 1.5m-3m (meter), and the net length is 2m-20m. The net meshes are rhombus or square. The blending twisting threads are made of a plurality of PVA monofilaments, the polyethylene monofilaments and the impregnation polyester threads or the impregnation nylon threads. Length and width of the net meshes are both 10cm-30cm (centimeter). The net lines are the blending twisting threads made up of the PVA monofilaments, the polyethylene monofilaments and the impregnation polyester threads or the impregnation nylon threads, so the nori cultivation net is low in water absorption and high in intensity, length and width of the net and the net meshes are all of a certain size, and the nori cultivation net is used for controlling planting density more conveniently during operation, and is favorable for improving nori yield.

Description

technical field [0001] The invention relates to a net, in particular to a culture net used for laver culture. Background technique [0002] At present, the tool that must be used in the process of artificial cultivation of laver is the aquaculture net. The commonly used aquaculture net is mostly made of vinylon stretch-cut yarn. Due to the rough surface of the vinylon stretch-cut yarn, there are fine fluff and low strength, resulting in a After soaking for a long time, the water absorption is high and the sinking phenomenon is serious. If the traditional network cable is too thick, the gravity will be large, the consumables will be large, and the carrying capacity will be small if it is too thin; Large or too small will directly affect the intensity of operation and planting, and then affect the yield. Contents of the invention [0003] In order to solve the deficiencies in the above problems, the present invention provides a laver cultivation net. [0004] In order to s...
