Kelp seedling cultivation curtain and kelp seedling cultivation technology

Abstract

The invention relates to the technical field of marine product cultivation, in particular to a kelp seedling cultivation curtain and a kelp seedling cultivation technology capable of largely reducing the cost. The kelp seedling cultivation curtain is characterized by being made by the blended spinning of vinylon and polyethylene by the weight ratio of 30% to 70%. The kelp seedling cultivation technology comprises the following steps: after spores are collected by 5 days to 16 days, centrally putting the kelp seedling cultivation curtain into a dark refrigeratory, and storing the kelp seedling cultivation curtain in static seawater with the temperature of 1 DEG C to 5 DEG C for 20 days to 110 days; changing the seawater every 15 days to 20 days; after the storage period, removing the kelp seedling cultivation curtain from the refrigeratory at night, and transferring the kelp seedling cultivation curtain into a kelp seedling cultivation storeroom with natural light; and keeping the temperature of flowing seawater in a seedling cultivation pool be from 8 DEG C to 14 DEG C and the illumination intensity be from 1,000 Lux to 4,000 Lux until the kelp seedling grows to 1 centimeter to 3 centimeters and reaches a storeroom outlet standard. The invention has the advantages that the treatment processes of beating a rope, soaking, cooking the rope, solarizing and extending the rope, knitting the curtain, singeing, cooking the curtain, and the like are not needed; the kelp seedling cultivation curtain can be used by only being soaked in freshwater and the seawater respectively for 2 days to 3 days before seedling cultivation; a bare curtain has low cost which is 30% to 60% of that of a brick red rope; the cost for reducing the temperature of seedling cultivation is reduced by 10% to 30%; and the cultivation cost of a whole summer kelp seedling can be reduced by 20% to 50%.

Description

Technical field: [0001] The invention relates to the technical field of marine product cultivation, in particular to a kelp seedling-raising curtain and a kelp seedling-raising technology that can greatly reduce costs. Background technique: [0002] As we all know, the kelp seedlings used for kelp cultivation are artificially attached to the kelp spores on the seedling curtain, and the seedling curtain is in the indoor nursery pond through technical measures and cultivation processes such as temperature control, light control, fertilization, washing and running water, so that the seedling density, The length reaches the standard specified in GB / T 15807. The collection of kelp spores in the north is generally carried out from late July to early August, and the seedlings are temporarily raised in the middle and late October. The entire indoor seedling cultivation time is 70 to 100 days. During this period, the water temperature in the nursery should be controlled between 5-8.5...

AI Technical Summary

Problems solved by technology

The deficiencies of the prior art: First, the treatment process of Hongzongqiang in the seedling device is complicated and the processing cost is high. The Hongzong rope needs to be hammered, soaked, boiled, dried, stretched, weaved, singeing, and boiled. The process consumes a lot of manpower, fuel and fresh water, which increases the cost of each seedling curtain by 10 to 15 yuan, and increases the cost of the bare curtain to 17 to 24 yuan. High, during the entire indoor seedling cultivation period of kelp seedlings, the nursery room is required to receive light from the roof and side windows during the day, and sometimes light bulbs are used for light. Increase, the cost of electricity used for refrigeration accounts for 40% to 50% of the total cost of seedling cultivation
