Description
Technical Field
The invention relates to the technical field of kelp cultivation, in particular to a method for block planting and harvesting of kelp.
Background
The traditional kelp cultivation process can be simply summarized into seedling frame and seedling curtain manufacturing, indoor seedling picking, indoor seedling growing, temporary sea culture, seedling clamping, sea area planting, sea area cultivation and sea area harvesting.
As shown in fig. 1, the conventional sea area planting means is to tie both ends of a seedling rope 2 attached/sandwiched with a kelp seedling 1 to two parallel floating ropes 3 for planting, and because the boom ropes 3 are difficult to install and take a long time, the boom ropes 3 need to be installed in the sea in advance through a peg rope 9 and a peg rope 10, and then a worker ties one root of the seedling rope attached/sandwiched with a kelp seedling to the two parallel boom ropes in a sea area. The working environment for carrying out the above operations in the sea is poor, and under the condition of sun exposure, the unstable operation problem caused by stormy waves must be endured, so that the working time and the probability of worker injury are greatly increased.
The conventional kelp harvesting mode is that after kelp is mature, the seedling rope is manually unhooked from the boom rope one by one, and then the seedling rope is manually dragged into the sampan one by one. The weight of the kelp on each seedling rope reaches hundreds of jin, and a large amount of labor is consumed for repeated operation of a single seedling rope.
At present, a mechanized kelp harvesting mode is adopted, and the boom rope and the seedling rope are dragged into a ship together. However, the boom rope is about 75 meters in length, and a large number of floating balls are arranged on the boom rope, so that the weight and the volume of the boom rope can be increased when the boom rope is integrally towed into the ship, and the harvesting difficulty is greatly increased.
