Cultivation seedling rope capable of preventing laminaria japonica from falling off, and seedling clamping method

Abstract

The invention discloses a cultivation seedling rope capable of preventing laminaria japonica from falling off. The seedling rope is prepared from the steps of weaving leftover materials of two piecesof carpets into a strand of rope anticlockwise; and carrying out clockwise weaving of three strands of ropes to obtain the cultivation seedling rope with the diameter of 2-3cm. The invention also provides a cultivation seedling rope seedling clamping method capable of preventing laminaria japonica from falling off, wherein the method comprises the steps of screwing the seedling rope into a loosened state in a direction opposite to the weaving direction of the seedling rope from one end of the cultivation seedling rope, forming gaps among the three strands of the seedling rope, clamping the root of an artificial laminaria japonica seedling in the gap in a direction vertical to the direction of the seedling rope, enabling the artificial laminaria japonica seedling root not to be exposed outof the seedling rope, and restoring the state before the three strands of ropes are screwed; taking four pieces of laminaria japonica seedlings which are clamped at an interval of 3-5cm as one group,and performing seedling clamping continuously at an interval of 25-30cm between groups until the seedling rope is full of the laminaria japonica seedlings. The methods of the invention can reduce therisk of falling off of the laminaria japonica, increase water flow and ensure adequate supply of nutritive salt, improve the illumination effect, and is beneficial to growth of laminaria japonica.

Description

technical field [0001] The invention relates to the technical field of kelp culture, in particular to a cultured seedling rope and a seedling clamping method for preventing kelp from falling off. Background technique [0002] Kelp (Laminaria japonica) is a large seaweed that grows in seawater. It belongs to the class Phaeaceae, and is a plant of the kelp family. It is rich in sodium alginate, iodine, fucoidan, mineral elements and multivitamins. It is an important chemical raw material. It is also a common marine food on the public table, a health food, and a high-quality bait for sea treasures such as abalone and sea urchin. Kelp is one of the most important economic algae in my country, and it is widely cultivated in Dalian, Shandong and Fujian. my country's kelp culture has a history of decades, and it is produced by floating raft culture in sea areas. [0003] At present, the setting of kelp floating rafts in the northern sea area is the same as that of wakame. The le...
