Description
Technical Field
The invention relates to a method for evaluating and comparing the unit fresh/dry weight yield and the water content of a cultured sargassum fusiforme primary product, which highlights a novel method for evaluating and comparing the unit fresh/dry weight yield and the water content of the cultured sargassum fusiforme primary product.
Background
Hizikia fusiforme (B)Sargassum fusiforme）Belonging to Phaeophyta, Cyclosphaerae, Fucales, Sargassaceae (Sargassaceae)Sargassum (Sargassum), a perennial large brown algae characteristic of the northwest coast of the pacific. The cave head area of Wenzhou city in Zhejiang province is the largest industrial base of sargassum fusiforme in China, the annual planting area is more than 1.1 ten thousand mu, and the main breeding mode is soft raft frame and hanging cultivation. And (4) carrying out artificial seedling clamping planting in batches from 9 to 12 months every year, and harvesting from 4 to 5 middle of the month in the next year.
In recent years, the evaluation and statistics of the existing large-scale seaweed cultivation area in China generally adopt a unit of 'sea mu', namely: the number of the 1000m seedling clamping rope is 1 mu (666.7 m)2). The early wild seedlings are artificially cultured, the soft raft frames are distributed with the distance of 0.6 m between the ropes (3.3 m), the actual water surface area occupied by 1 sea mu is close to 1 mu, but the seedling clamping number of single seedling ropes of different farmers is different. With the continuous development of the development of high-quality germplasm of economic algae in China, the biological properties of high-quality germplasm such as sargassum fusiforme, kelp and undaria pinnatifida are obviously improved, and the length of algae of a new variety or a new strain is continuously increased, so that the distance between seedling clamping ropes is continuously increased, the actual water surface area occupied by the layout of 1-acre seedling clamping ropes is far larger than that of an international unit of acre, and the number of seedlings clamped by a single seedling adding rope is still different greatly. At present, the unit yield evaluation of the sargassum fusiforme is generally calculated by average fresh species and dry weight of single seedling ropes, and evaluation parameters such as actual unit area selection (sea mu or mu), single seedling rope seedling clamping number, unit area total seedling rope number and the like are ignored, so that the unit yield evaluation value and the actual unit yield value have large difference. How to carry out classification evaluation of the unit yield per acre or acre of the large-scale seaweed in China in a standardized way, scientifically evaluating the unit yield, scientifically comparing the unit yield difference on time or space variables and accurately evaluating the annual total yield and the total yield of various large-scale seaweed is the technical problem to be solved by the invention.
A method for evaluating and comparing the unit fresh weight yield, dry weight and water content of primary products of cultivated sargassum fusiforme mainly relates to the seven aspects of counting and length measurement of seedling clamping ropes, cleaning and impurity removal, parameter evaluation, calculation (kg) of unit fresh/dry weight yield, calculation (kg) of fresh weight water content, comparison of unit fresh/dry weight yield (kg) difference, comparison of unit dry weight water content (%) difference and the like. The technical problem to be solved by the invention is to accurately implement the evaluation and comparison operation of fresh/dry weight yield and water content per mu of sea area or unit mu in each stage so as to select the artificially purified new variety of cultured sargassum fusiforme and the culture period which are most suitable for the local cultured sea area, and to highlight the scientificity of unit yield evaluation and comparison of the primary products of cultured sargassum fusiforme.
Disclosure of Invention
Based on the problems, the invention aims to provide the unit fresh/dry weight yield and water content evaluation and comparison method for the primary products of the cultured sargassum fusiforme, the method can efficiently evaluate and compare the unit yield and difference of different excellent strains of the cultured sargassum fusiforme, and provides a technical basis for the culture area evaluation and total yield statistics of the industry for culturing the sargassum fusiforme.
In order to solve the above problems, the present invention provides the following technical solutions: a unit fresh/dry weight yield and water content evaluation comparison method for a cultured sargassum fusiforme primary product is characterized by comprising the following steps:
1. seedling clamping rope counting and length measuring device
The sargassum fusiforme is cultivated by clamping seedlings with polyethylene microscopic ropes with the diameter of 0.5 cm, the length is usually 3.3 m, and a soft raft frame single-rope flat-hanging and double-rope flat-hanging fine variety cultivation mode can be adopted. The seedling clamping rope can be recycled, but the length of the seedling clamping rope which is recycled is more than 3.3 m under the influence of long-term tension. According to the basic theoretical requirements of statistics, the invention implements small sample random sampling, namely: randomly collecting the number (n) of seedling clamping ropes of the primary products of the additionally cultivated sargassum fusiforme, measuring the actual length (m) of the selected seedling clamping ropes, and calculating the average length (m) of the seedling clamping ropes.
2. Cleaning and removing impurities
The surface of the fresh alga of the cultivated sargassum fusiforme is distributed with more algin, and the algin has adsorptivity to silt. Meanwhile, under the condition of high-density cultivation, the cultivated sargassum fusiforme population is easy to be mixed with attached algae, grass sticks and household garbage, and the impurities can influence the yield evaluation. Therefore, the sargassum fusiforme stored on the bank needs to be cleaned under high pressure by using seawater filtered in advance to remove silt adsorbed on the surfaces of the alga bodies, and impurities such as miscellaneous algae, straw sticks, household garbage and the like are manually removed.
3. Evaluating parameters
The seedlings of the cultivated sargassum fusiforme belong to single clamped seedlings, and the single characteristic is obvious in the subsequent growth and development process, so that the number of the sargassum fusiforme of each clamped seedling rope, the fresh weight of the single plant, the dry weight of the naturally aired single plant and the dry weight of the naturally aired single plant are set as evaluation parameters. According to the number of randomly sampled seedling clamping ropes (n is more than or equal to 5, small samples), the number of single ropes (mean value, n is more than or equal to 20), fresh weight (mean value, n is more than or equal to 30, large samples), natural drying dry weight (mean value, n is more than or equal to 30, large samples) and drying dry weight mean value at constant temperature of 80 ℃ (mean value, n is more than or equal to 30, large samples) are calculated.
4. Calculation of the yield per unit fresh weight of acre
In China, the length of the seedling rope is 1000 meters, and the unit is 1 mu of sea area, and the distance between the seedling rope and the seedling rope is not calculated (the step 5 and the step 6 are the same). Therefore, the invention calculates the yield of the fresh weight per acre according to a mathematical formula that the yield per acre (kg/acre) = the fresh weight per unit of single plant (mean value, kg/plant, n is more than or equal to 30) × the number of single-rope plants (mean value, the minimum mean number of single-rope plants is calculated by the same standard, plant/strip) × [ 1000m ÷ length of the seedling clamping rope (mean value, strip, n is more than or equal to 5) ].
5. Calculation of yield per dry weight of Haima (Natural drying or constant temperature drying at 80 deg.C)
The yield per dry weight per sea mu is calculated according to a mathematical formula that the yield per dry weight per sea mu (kg/sea mu) = the dry weight per single plant (mean value, kg/plant, n is more than or equal to 30) × the number of single-rope plants (mean value, minimum mean number of single-rope plants is calculated by the same standard, plant/strip) × [ 1000m ÷ length of seedling clamping rope (mean value, strip, n is more than or equal to 5) ].
6. Calculation of water content quality of fresh weight yield per unit of acre
The invention calculates the water content quality of the fresh weight per sea mu according to a mathematical formula that the water content quality (kg) per fresh weight per sea mu is not equal to the fresh weight per sea mu, namely the fresh weight per sea mu, and the dry weight per sea mu, namely the dry weight per sea mu.
7. Calculation of yield and water content per dry unit area of sea mu
The water content of the unit dry weight yield per mu is calculated according to a mathematical formula of 'water content (%) per unit dry weight yield per mu, = [ unit yield of naturally airing (kg/mu) -80 ℃ constant-temperature drying (kg/mu) ]/unit yield of naturally airing (kg/mu) × 100%'.
8. Calculation of mu unit fresh weight yield
International macroalgae cultivation on flat wall at 666.7m2The water surface area is counted as 1 mu of evaluation unit, and whether the water surface is vacant in the middle is not calculated. Therefore, the invention is based on the standard that the unit fresh weight per mu (kg/mu) = single fresh weight (mean value, kg/plant, n is more than or equal to 30) multiplied by the number of single rope plants (mean value, minimum mean number of single rope plants is calculated by the same standard, plants/strip) multiplied by 666.7m2Length of seedling clamping rope (mean value, strip, n is greater than or equal to 5) multiplied by seedling rope spacing) +
Length of seedling clamping rope (mean value, strip, n is more than or equal to 5)]"mathematical formula" to calculate the fresh weight output per mu unit.
9. Calculation of mu unit dry weight yield
The invention is characterized in that the unit yield per mu (kg/mu) = single dry weight (mean value, kg/plant, n is more than or equal to 30) × single rope number (mean value, minimum mean number of single rope, same standard, plant/strip) × [666.7m ]2Length of seedling clamping rope (mean value, strip, n is greater than or equal to 5) multiplied by seedling rope spacing) +
Length of seedling clamping rope (mean value, strip, n is more than or equal to 5)]"mathematical formula" to calculate the unit dry weight yield per mu.
10. Calculation of water content quality of mu unit fresh weight yield
The water content quality of the unit of mu fresh weight is calculated according to a mathematical formula of 'unit of mu fresh weight yield water content quality (kg) = unit of mu fresh weight yield (kg/mu sea) -unit of mu dry weight yield (kg/mu sea)'.
11. Calculation of water content per unit dry weight yield per mu
The water content of the unit dry weight per mu is calculated according to a mathematical formula of 'water content (%) per unit dry weight per mu unit, = [ unit yield (kg/mu) of naturally airing-80 ℃ constant-temperature drying (kg/mu) ]/unit yield (kg/mu) of naturally airing-100%'.
The unit fresh/dry weight yield and water content difference of the primary products of the cultivated sargassum fusiforme are mainly reflected in three characteristics of strains, cultivated sea areas and growth time, although the sea acres and acres have different basic evaluation standards, the fresh/dry weight and water content difference have the same condition on the premise of comparison, and the fresh weight/dry weight/water content difference comparison among the samples of the unit yield of the same strain, the same cultivated sea areas and different growth time is shown; comparing the fresh weight/dry weight/water content difference among samples of the same strain, different culture sea areas and the same growth time and unit yield; comparing the difference of fresh weight/dry weight/water content between samples with different strains, the same culture sea area and the same growth time and unit yield, and comparing the difference of fresh weight/dry weight/water content between samples with different strains, different culture sea areas and the same growth time and unit yield. Through the evaluation and comparison method, the yield (fresh weight/dry weight/water content) of different strains, cultivation sea areas, growth time and sea acres/acre of sargassum fusiforme can be rapidly and scientifically calculated, so that the artificially purified new strains and cultivation periods of the cultivated sargassum fusiforme which are most suitable for the local cultivation sea areas can be selected.

(7) calculation of yield and water content per unit dry weight per mu
According to a mathematical formula that the water content of the unit dry weight yield per mu of the sea is not = the unit yield of naturally airing at-80 ℃ constant temperature drying/the unit yield of naturally airing is 100% ";
(8) mu unit fresh weight yield calculation
International macroalgae cultivation on flat wall at 666.7m2The water surface area is counted as 1 mu evaluation unit according to the conditions that the unit fresh weight yield per mu = the fresh weight of a single plant x the number of single rope plants x [666.7m ]2Divide (length of seedling clamping rope x distance of seedling rope) +
Length of seedling clamping rope]The yield of unit fresh weight per mu is calculated by a mathematical formula, wherein the unit fresh weight is more than or equal to 30kg, and the length of a seedling clamping rope is more than or equal to 5 m;
(9) mu unit dry weight yield calculation
According to the conditions that the yield per unit dry weight per mu = single dry weight multiplied by single rope number multiplied by [666.7m ]2Divide (length of seedling clamping rope x distance of seedling rope) +
Length of seedling clamping rope]The unit dry weight yield per mu is calculated by a mathematical formula, wherein the unit dry weight is more than or equal to 30kg, and the length of a seedling clamping rope is more than or equal to 5 m;
(10) calculation of water content per mu fresh weight yield
Calculating the water content quality of the fresh weight per mu according to a mathematical formula that the water content quality of the fresh weight per mu is = the fresh weight per mu-dry weight per mu;
(11) mu unit dry weight yield water content calculation
According to a mathematical formula that the water content of the unit dry weight output per mu is not= [ the unit output of natural drying at the constant temperature of 80 ℃ below zero and the unit output of drying at the constant temperature ]/the unit output of natural drying is 100% ";
