Abstract
Provided is an acid treatment type full-floating laver culture method. According to the method, by the utilization of high desiccation tolerance of laver, organic acid is utilized, appropriate nitrogenous fertilizer or appropriate phosphate fertilizer is added, acid soaking or spraying soaking is carried out on a laver seedling net, then the effect for getting rid of wild seaweeds and diatoms is achieved, and the aim of being equal to physical drying out is achieved. Compared with an ordinary full-floating laver culture method, the acid treatment type full-floating laver culture method has the advantages that no wild seaweed erodes, the laver is free of the diatoms, the quality of the laver is high, and the growing period is long. Compared with an ordinary laver inserted rod type culture method, the acid treatment type full-floating laver culture method has the advantages that the productivity is higher by 20%, the harvesting intervals are short, and the working intensity is low. Compared with a semi-floating type laver culture method, the acid treatment type full-floating laver culture method has the advantages that the laver culture can be carried out in deep water areas, and the productivity is high.
Description
Technical field
The present invention relates to a kind of laver culture technology, particularly a kind of acid treatment formula laver floating method.
Background technology
Laver culture Main Cultivation mode has 2 kinds, is respectively inserted-link type and semi-floating.Concrete feature is as follows:
The cultivation of laver inserted-link type has another name called column support type raft culture, utilizes inserted link to carry out laver and does, and compares floating, and the cultivation depth of water is restricted, only has 3-8 rice; Quality is better.It is one of current main flow breeding way.
The cultivation of laver semi-floating has another name called semifloating raft culture, refers to and in intertidal zone, carries out laver cultivation, and feature is to float at the incoming tide at the water surface, during ebb tide, does, and cultivation is subject to area and the position limitation of beach, and quality is better.It is one of current main flow breeding way.
Laver floating has another name called all-floating raft type cultivation, refers in deepwater field and carries out laver cultivation, and feature is that laver lace curtaining does not surface, and cultivation lace curtaining is not done, and growth cycle is short.Owing to not doing, so easily there is the problems such as the assorted algae of lace curtaining adheres to, and diatom is adhered on blade face, affects laver quality, and the culture-cycle is short.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, has proposed the acid treatment formula laver floating method that the assorted algae of a kind of nothing corrodes, quality is high, vegetative period is long, output is high.
The technical problem to be solved in the present invention is achieved through the following technical solutions, and a kind of acid treatment formula laver floating method, is characterized in that concrete steps are as follows:
1) make acid solution
(1) using acid is organic acid;
(2) in workboat, add seawater, according to the mass ratio of 3-10%, acid is poured in seawater, with PH test paper test acid solution pH value, regulating acid solution pH value is 2.0-2.4;
(3) mass ratio of pressing 5-30% adds nitrogenous fertilizer or phosphate fertilizer;
2) lace curtaining carries out acid treatment
(1) adopt immersion way, method is as follows: laver lace curtaining is soaked into acid solution, and the time is 8-10 second, then lace curtaining is put into seawater depickling;
Or adopt and to spray mode, method is as follows: use porphyrilic acid treatment facility to spray laver lace curtaining, the time is 8-10 second; Sprayed latter 8 ~ 10 seconds, then lace curtaining has been put into seawater depickling;
(2) after a collection of laver lace curtaining of every processing, should test acid solution pH value, timely supplemental acid and seawater, keeping acid solution pH value is 2.0-2.4;
3) treatment cycle
The seeding stage view curtain algae adhesion condition of mixing, processes 2-3 time; Mature stage was processed once every 13 ~ 16 days;
4) laver convalescence
Laver culture seedling net after processing, need, through above sea area cultivation in 7 days to carry out nutrition conversion and blade face reparation, can gather in the crops.
The technical problem to be solved in the present invention can also be come further to realize by the following technical programs, and described organic acid is formic acid or citric acid.
The present invention compared with prior art, utilizes laver to have stronger dry tolerance, uses acid that laver seedling net is carried out acid soak or sprayed, thereby reaches the effect of removing assorted algae, diatom, reaches and is equal to the object that physics is done.This acid treatment formula laver floating is compared and is had the following advantages with Tzu Tsai floating: without assorted algae, corrode, frond is without diatom, and quality is high; Vegetative period is long.Cultivation is compared and is had the following advantages with Tzu Tsai inserted-link type: output height is approximately high more than 20%, and the interval of gathering is short, and working strength is low.Compare with semi-floating laver culture: can carry out laver culture in deepwater field.Output is high.
Embodiment
An acid treatment formula laver floating method,
1) make acid solution
(1) using acid is organic acid, can not use industrial waste acid, generally uses formic acid or citric acid;
(2) at workboat, add the about 10cm of seawater left and right, according to the mass ratio of 3%-10%, acid is poured in seawater, with PH test paper test acid solution pH value, regulating acid solution pH value is 2.0-2.4;
(3) nitrogenous fertilizer or phosphate fertilizer, because water quality is thinner, are added by the mass ratio of 5-30% in part sea area;
2) soak or spray
(1) adopt immersion way, method is as follows: laver lace curtaining is soaked into acid solution, and the time is 8-10 second, then lace curtaining is put into seawater depickling;
Or adopt and to spray mode, method is as follows: use porphyrilic acid treatment facility to spray laver lace curtaining, the time is 8-10 second; Sprayed latter 8 ~ 10 seconds, then lace curtaining has been put into seawater depickling;
(2) after a collection of laver lace curtaining of every processing, should test acid solution pH value, timely supplemental acid and seawater, keeping acid solution pH value is 2.0-2.4;
3) treatment cycle
The seeding stage view curtain algae adhesion condition of mixing, processes 2-3 time; Mature stage was processed once every 13 ~ 16 days; Depending on assorted algae adhesion condition, increase and decrease.
4) laver convalescence
Laver culture seedling net (seedling net consists of some lace curtainings) after processing, need, through above sea area cultivation in 7 days to carry out nutrition conversion and blade face reparation, can gather in the crops.
